Magnetism and Electricity Class 8 Questions and Answers Notes

Let’s Assess

Question 1.
A student is trying to make a device to find direction using a magnetic needle. For this, he places the magnetic needle inside a box made of iron.
a) Will this device work properly?
b) Explain your answer.
c) What changes should be made to make this device work properly?
Answer:
a) No, the device will not work properly.

b) Iron is a magnetic material with high permeability. This means it allows the Earth’s magnetic field lines to pass through it very easily. The iron box will attract all the magnetic field lines, causing them to pass through the walls of the box instead of passing through the inside. The compass needle inside will be shielded from the Earth’s magnetic field and will not align to the North-South direction. This is called magnetic shielding.

c) The box should be made of a non-magnetic material (an insulator) that does not interfere with magnetic field lines. Examples: A box made of plastic, cardboard, wood, or aluminum.

Question 2.
AB is a bar magnet shown in the figure below. An iron rod CD is placed near its B pole.
• Which magnetic poles will be formed at the ends C and D?
• Which property of magnets does this phenomenon demonstrate?

Answer:
This is an example of Magnetic induction.

• The pole nearer to the magnet gets the opposite polarity.
• The pole farther from the magnet gets the same polarity.

Therefore:

• End C (nearer to B’s South pole) will become a North pole (N).
• End D (farther from B’s South pole) will become a South pole (S).

This phenomenon demonstrates Magnetic Induction. Magnetic Induction is the phenomenon where a magnetic substance acquires magnetism (Induced Magnetism) due to the presence of a magnet.

Question 3.
A bar magnet and a U magnet are shown in figures (a, b) each having two iron nails hanging from them.
a. Which is the correct figure in each case?
b. Explain the reason clearly.

Answer:
a.

• For the bar magnet: Figure A is correct.
• For the U-magnet: Figure B is correct.

b. Reason: The nails are magnetized by magnetic induction. When induced, the like poles (which form at the free ends of the nails) will repel each other.

In Figure A (Bar magnet): The magnet’s pole (e.g., North) induces an opposite pole (South) at the head of both nails and a like pole (North) at the tips. Since both tips are North poles, they repel each other and move apart.

In Figure B (U-magnet): The two poles of the U-magnet (N and S) are used. The nail on the N pole gets an S pole at its head and an N pole at its tip. The nail on the S pole gets an N pole at its head and an S pole at its tip. Since the free tips of the nails are now unlike poles (N and S), they will attract each other and move closer.

Question 4.
You are given a soft iron piece, a steel piece of the same size, insulated copper wire and a battery:
a. Suggest a method to make a powerful permanent magnet.
b. Suggest a method to make a temporary magnet.
Answer:
a. To make a permanent magnet, you must use the steel piece, which has high retentivity (the ability to retain magnetism).

• Method: Wrap the insulated copper wire around the steel piece many times to create a coil.
• Connect the ends of the wire to the battery and pass a strong electric current through it for some time.
• Even after the battery is disconnected, the steel will retain its magnetism.

b. To make a temporary magnet (an electromagnet), you must use the soft iron piece, which has high susceptibility (gets magnetized easily) but low retentivity (loses magnetism quickly).

• Method: Wrap the insulated copper wire around the soft iron piece.
• Connect the ends of the wire to the battery.
• The soft iron will become a strong magnet only as long as the electricity is flowing. It will lose its magnetism when the battery is disconnected.

Question 5.
In an experiment, a plastic car with an iron piece inside it, is made to run on a wooden table by sliding a strong magnet below it.
a) The experiment failed when a steel table was used. What is the reason for this?
b) If an aluminium table is used instead of steel, what will happen? Why?
Answer:
a) Reason: Magnetic Shielding.
Steel is a magnetic material (like iron). When the magnet is moved under the steel table, the steel table’s high permeability causes the magnetic field lines to pass through the table itself rather than passing above the table to reach the car. The steel table effectively shields the iron piece in the car from the magnet’s force, so the car does not move.

b) What will happen: The experiment will work.
Why: Aluminium is a non-magnetic material (like plastic or wood). It does not block or interfere with magnetic field lines. The magnetic field from the magnet will pass through the aluminium table easily and attract the iron piece in the car, making it move.

Answer:

Textbook Page No : 188 & 189

Question 3.
What happens when the north pole of a magnet is brought near to the north Dole of another maanet?

observe the changes and complete the table.
Answer:

Activity	Observation
When the north poles are brought close to each other	Repels
When the north pole and the south pole are brought close to each other	Attracts
When the south poles are brought close to each other	Repels

Question 4.
Why is the pencil not falling down and floating in the air like this?
Answer:
The pencil is floating because of magnetic levitation. The magnetic force of repulsion between the magnets on the pencil and the magnets on the cardboard is strong enough to balance the force of gravity, causing the pencil to float in the air.

Question 5.
Can you move the pencil backward without touching it? How can it be possible?
Answer:
Yes, it’s possible. You can move the pencil by bringing another magnet near one of the floating magnets. If you bring a like pole (e.g., North pole to North pole), the repulsion will push the floating magnet and the pencil away.

Question 6.
What will happen if you bring another magnet near one side of the top magnet?
Answer:
It depends on which pole you bring close. If you bring a like pole near the top magnet, it will repel and move away. If you bring an unlike pole near it, it will attract and move towards the magnet you are holding.

Question 7.
Do you know if this special property of magnet is used in any technology?
Answer:
Maglev (Magnetic Levitation) Trains

Question 8.
What are Maglev trains?
Answer:
This is a major technology that uses magnetic levitation.

• Maglev trains are trains that run with out wheels.
• They use powerful electromagnets on the train and the track to repel each other.
• This levitates (suspends) the train above the track.
• Advantage: The absence of physical contact eliminates friction. This allows Maglev trains to reach extremely high speeds with minimal energy loss, and provides a quieter, smoother ride.

Textbook Page No : 190 & 191

Question 9.
When a bar magnet is suspended freely, in / which direction does it align?

Answer:
If a magnet can move freely, it always aligns in the north-south direction of the Earth.

Question 10.
Why does a magnetic compass always show the north-south direction?
Answer:
It is because of the influence of the Earth’s magnetic field. The Earth acts like a giant magnet with its own magnetic poles. The magnetic north pole of the Earth is near the geographic south pole, and the Earth’s magnetic south pole is near the geographic north pole.

Question 11.
How can we make an artificial magnet?
Answer:
You can make one by taking a magnetic material (like a hacksaw blade) and rubbing it with one pole of a strong magnet. You must rub it repeatedly in the same direction from one end to the other.

Textbook Page No : 192 & 193

Question 12.
How can you identify the poles of a ring magnet or a U-shaped magnet?
Answer:
You can use a magnetic compass (magnetic needle). If the north pole of the compass needle (often the red end) is repelled, that part of the magnet is a North pole. If the north pole of the compass is attracted, that part of the magnet is a South pole.

Question 13.
What is your conclusion after breaking a magnet into smaller pieces?
Answer:
No matter how small a magnet is, it will always have two poles (a north and a south pole). A magnet with only one pole (a monopole) does not exist.

Textbook Page No : 195 & 196

Question 14.
Is the distribution of magnetic field lines the same everywhere?
Answer:
No, the distribution of magnetic field lines is not the same everywhere around a magnet. The spacing of the lines indicates the strength of the magnetic field.

Question 15.
How is magnetic field strength related to magnetic field lines?
Answer:
The magnetic field is strongest where the magnetic field lines are closest together. These areas have a higher magnetic flux density.

Question 16.
What will happen to the magnetic flux if the size of the surface it passes through increases?
(Increase/ decrease)
Answer:
The magnetic flux will increase. Since magnetic flux is the total number of field lines passing perpendicular / normally through a surface, a larger surface will catch more lines.

Question 17.
Is the magnetic flux density higher at the poles of a magnet or at other places?
Answer:
The flux density is higher at the poles. The text states, “The poles of a magnet have the highest magnetic flux density.”

Question 18.
In the experiment with iron filings in a bottle (Fig 11.19), where do the filings stick the mo¬st and where do they stick the least?

Answer:
Most: The iron filings stick the most at the poles of the magnet.

Least: The filings are seen the least in the middle of the magnet, away from the poles. This happens because the magnetic field strength is greatest at the poles and gets weaker as you move away from them.

Textbook Page No : 197 & 198

Experiment (Fig. 11.20 & 11.21)

Question 19.
“Bring another pin near the free end of the first pin. Isn’t the second needle getting attracted?”
Answer:
Yes, the second pin gets attracted. This is because the first pin has become an induced magnet and can now attract other magnetic substances.

Question 20.
“Now, bring a magnetic compass near the free end of the needle. Isn’t the direction of the compass needle changing?”
Answer:
Yes, the direction of the compass needle changes. This confirms that the first pin has acquired Induced Magnetism and is acting as a magnet with defined poles.

Question 21.
“Then, carefully remove the first needle from the magnet. Does it still show magnetic properties? Write your observations in the science diary.”
Answer:
Observation: The first pin will still show some magnetic properties (attract paper clips or other pins) immediately after being removed, but this induced magnetism will be temporary and quickly weaken, depending on the material the pin is made of (e.g., iron or steel).

Question 22.
“What are the uses of magnetic induction? Discuss.”
Answer:

• Used in making electromagnets, where soft iron cores are induced to become temporary magnets.
• It is the principle by which a permanent magnet can attract non-magnetized magnetic objects (like iron nails).
• Used in magnetic separation techniques and the operation of certain electrical devices.

Question 23.
Which of these has greater susceptibility? (Soft iron/Steel)
Answer:
Soft iron.

Question 24.
Which of these has greater retentivity? (Soft iron/Steel)
Answer:
Steel

Textbook Page No : 199 & 200

Question 25.
Based on the characteristics you observed, which is more suitable for making strong temporary magnets, soft iron or steel?
Answer:
Soft iron is more suitable. Temporary magnets (electromagnets) need to acquire magnetism easily (high susceptibility) and lose it quickly (low retentivity) when the current or external field is removed.

Question 26.
When making permanent magnets, which magnetic property of steel should be utilised?
Answer:
The property of high retentivity should be utilised. Permanent magnets need to retain their magnetism for a long time.

Permeability and Experiment

Question 27.
What do you observe?
Answer:
Observation: When the iron filings are sprinkled and the plate is tapped, the filings will cluster around the magnets but will not stick to the area over the gap (the hole) in the large iron nut. The magnetic field lines are concentrated through the iron nut, bypassing the area where the air gap is.

Question 28.
Are the iron filings sticking to the area where the gap in the iron nut is present?
Answer:
No, the iron filings are not sticking to the area where the gap in the iron nut is present.

Question 29.
What conclusion do you reach?
Answer:
Conclusion: Soft iron (like the iron nut) has a higher ability than air to allow magnetic field lines to pass through it. The magnetic field lines prefer to travel through the path of least resistance, which is the soft iron, rather than the air gap.

Question 30.
Why do compass needles not show direction when placed inside a box made of soft iron?
Answer:
Explanation: Soft iron has very high permeability. When a compass is placed inside a soft iron box, the soft iron effectively diverts the Earth’s external magnetic field lines, causing them to pass through the box material instead of the air inside it. This magnetic shielding effect prevents the magnetic field from reaching the compass needle, so the needle cannot align itself with the Earth’s field and show direction.

Question 31.
Electromagnet Experiment; complete the table

Answer:

Experiment	Observation
When electricity flows, the soft iron piece and the paper clips	attracts
After removing the cell, the soft iron piece and the paper clips	does not attract

Question 32.
Based on this experiment, can you write down the different ways to increase the strength of an electromagnet?
Answer:

• Increasing the number of turns of the coil around the soft iron core.
• Increasing the current flowing through the coil (by increasing the number of cells/battery voltage).
• Increasing the cross-sectional area of the soft iron inside the coil.
• Using a core material with higher permeability (like soft iron).

Question 33.
Let’s write examples of devices that use electromagnets

Answer:

• Electric bells
• Loudspeakers
• Cranes (used to lift heavy iron objects)

Question 34.
What is the charge of the paint droplets?
Answer:

Electromagnets	Permanent Magnets
Poles can be changed	The gained magnetism can be retained for a long time
Magnetic strength can be changed/ varied (by changing the current or number of turns)	Magnetic strength cannot be increased

Class 8 Basic Science Chapter 11 Question Answer Extended Activities

Question 1.
What is the important role of neodymium magnets in electric vehicles (EVs)? How does the use of these magnets affect the vehicle’s efficiency, speed, and driving range? Collect information about this and prepare a report.
Answer:
Neodymium magnets are used to create permanent magnet synchronous motors (PMSM), which are highly efficient and powerful.

Efficiency: PMSMs with neodymium magnets are very efficient, converting a large percentage of electrical energy into mechanical energy.

Speed/Power: They allow for high power density, enabling faster acceleration and higher top speeds.

Driving Range: The high efficiency reduces energy consumption, leading to an extended driving range for the EV on a single charge.

Question 2.
Build a model of a vehicle that operates using magnetic levitation. Prepare a slide/chart explaining its working principle.
Answer:
This is a project-based activity involving building a model (e.g., a simple Maglev train model).

Working Principle (for the slide/chart): Magnetic levitation works using repulsive forces between magnets (either permanent magnets or electromagnets) to lift the vehicle above the track, eliminating friction. An electromotive force is then used to propel the vehicle forward.

Class 8 Basic Science Magnetism and Electricity Notes Kerala Syllabus

Magnets are objects that can attract (ആകർഷിക്കുക) and repel (വികർഷിക്കുക) other objects. This property is called magnetism. Magnets are used in many devices.

Examples of Magnet Uses

• MRI scanning machines
• Headphones and speakers
• Magnetic compass
• Electric motors
• Maglev trains (Magnetic Levitation)

ആകർഷിക്കാനും വികർഷിക്കാനും കഴിവുള്ള വസ് തുക്കളാണ്. കാന്തങ്ങൾ. കാന്തിക ബലം ഉപയോഗി ച്ച് വസ്തുക്കളെ വായുവിൽ ഉയർത്തി നിർത്താൻ സാധിക്കും (Magnetic levitation).

Natural Magnets & Artificial Magnets

Natural Magnets (പ്രകൃതിദത്ത കാന്തങ്ങൾ)

• These are magnets that are obtained directly from nature.
• Example: Lodestone, Magnetite

Artificial Magnets (കൃത്രിമ കാന്തങ്ങൾ)

• These are magnets made by people in specific shapes, sizes, and strengths.
• They are typically made using metal alloys (ലോഹസങ്കരങ്ങൾ).

Types of Artificial Magnets
Artificial magnets are made from d materials.

• Alnico Magnets:
  These are alloys made from aluminum (Al), nickel (Ni), cobalt (Co), and iron (Fe).
• Ceramic/Ferrite Magnets
  These are made by mixing iron oxide with carbonates of elements like barium or strontium.
• Electromagnet
  This is a temporary magnet made by passing electricity through a wire coiled around a soft iron core.

General Properties of Magnets (കാന്തത്തിന്റെ പൊതുവായ സവിശേഷതകൾ)
1. Poles Exist in Pairs: Every magnet has two poles, a North pole (N) and a South pole (S). A magnet with only one pole (monopole) does not exist. If you break a magnet, each piece becomes a new, complete magnet (Each has two poles)
‘ഒരു കാന്തത്തെ എത്ര ചെറുതാക്കിയാലും, അതിന് എപ്പോഴും ഒരു ഉത്തരധ്രുവവും ദക്ഷിണധ്രുവവും ഉണ്ടായിരിക്കും. ഒരൊറ്റ ധ്രുവം (N or S) മാത്രമായി ഒരു കാന്തത്തിന് നിലനിൽക്കാൻ കഴിയില്ല.

2. Attraction & Repulsion: The fundamental law of magnetism is:

• Like poles repel ((സജാതീയ ധ്രുവങ്ങൾ വികർഷിക്കുന്നു.) (e.g., N-N or S-S).
• Unlike poles attract (വിജാതീയ ധ്രുവ ങ്ങൾ ആകർഷിക്കുന്നു) (e.g., N-S).

3. Directional Property: If a magnet is suspended freely (like being suspended by a string), it will always align itself with the Earth’s North-South direction.
ഒരു കാന്തത്തെ സ്വതന്ത്രമായി തൂക്കിയിട്ടാൽ, അത് എപ്പോഴും ഭൂമിയുടെ വടക്ക് തെക്ക് ദിശയിൽ വന്ന് നിൽക്കും. ഇതാണ് കാന്തത്തിന്റെ ദിശാസൂചക സ്വഭാവം.

Application: This is the working principle of a Magnetic Compass (വട ക്കുനോക്കിയന്ത്രം).).

• A compass is a device that uses this property.
• It contains a small magnetic needle that can rotate freely.
• This needle always points to the Earth’s North-South direction, allowing us to easily determine all other directions (East, West).

4. Magnetic Levitation: The repulsion of like poles can be used to make an object float, balancing the force of gravity (e.g., Maglev trains).

Maglev Trains

• This is a major technology that uses magnetic levitation.
• Maglev trains are trains that run without wheels.
• They use powerful electromagnets on the train and the track to repel each other.
• This levitates (suspends) the train above the track.
• Advantage: The absence of physical contact eliminates friction. This allows Maglev trains to reach extremely high speeds with minimal energy loss, and provides a quieter, smoother ride.

The Earth as a Giant Magnet (ഭൂമി ഒരു വൻകാന്തം)
The directional property of a compass works because the Earth itself acts like a big magnet, with its own magnetic field and poles.

• Cause of Earth’s Magnetism: This magnetic nature is believed to be caused by the movement of large amounts of molten iron and nickel in the Earth’s inner core.
• The “Pole-Swap”: The Earth’s magnetic poles are inverted compared to its geographic poles.
  1. The Earth’s Magnetic South Pole is located near the Geographic North Pole (the “top” of the world).
  2. The Earth’s Magnetic North Pole is located near the Geographic South Pole (the “bottom” of the world).
• How a Compass Works: A compass needle’s North pole is attracted to the Earth’s Magnetic South Pole (which is at our Geographic North). This is why a compass needle always points north!

ഭൂമി ഒരു വലിയ കാന്തമായി പ്രവർത്തിക്കുന്നു. ഭൂമിയുടെ കാന്തിക ദക്ഷിണ ധ്രുവം (Magnetic South Pole) അതിന്റെ ഭൂമിശാസ്ത്രപരമായ ഉത്ത ര ധ്രുവത്തിന് (Geographic North Pole) അടു ത്താണ്. ഒരു വടക്കുനോക്കിയന്ത്രത്തിലെ കാന്ത സൂചിയുടെ ഉത്തരധ്രുവം (N pole), ഭൂമിയുടെ ഈ കാന്തിക ദക്ഷിണ ധ്രുവത്താൽ ആകർഷിക്ക പ്പെടുന്നു. ഇതുകൊണ്ടാണ് കാന്തസൂചി എപ്പോഴും വടക്ക് ദിശയിലേക്ക് തിരിഞ്ഞുനിൽക്കുന്നത്.

Magnetisation (കാന്തവൽക്കരണം)
We can create artificial magnets using a process called magnetisation. One common way is the “single-touch” method.

Procedure (Fig. 11.12):

1. Place a hacksaw blade on a table.
2. Take a strong bar magnet. Using one pole (e.g., the North pole), rub the blade starting from one end (A) to the other end (B).
3. Lift the magnet and bring it back to end A.
4. Repeat this process several times, always rubbing in the same direction (A to B).

• Result: The hacksaw blade will become a magnet. The end where the rubbing starts (A) will become the North pole, and the end where the rubbing ends (B) will become the South pole.

• Observation (Fig. 11.13): When a magnet is broken into smaller pieces, each piece instantly becomes a new, complete magnet with its own North pole and South pole.
• Conclusion: “No matter how small a magnet is, it will always have two poles. A magnet with only one pole does not exist.” (These single poles are called ‘monopoles’).

ഒരു കാന്തത്തെ ഏത് ചെറിയ കഷണങ്ങളായി മുറിച്ചാലും, ആ ഓരോ കഷണവും ഒരു പൂർണ്ണ കാന്തമായിരിക്കും (അതിന് സ്വന്തമായി ഒരു നോ ർത്ത് പോളും സൗത്ത് പോളും ഉണ്ടാകും). ഒരു ധ്രുവം (Nor S) മാത്രമുള്ള ഒരു കാന്തത്തെ (magnetic monopole) നിർമ്മിക്കാൻ സാധ്യമല്ല.

Magnetic Field and Field Lines (കാന്തിക മണ്ഡലവും മണ്ഡലരേഖകളും)
Magnetic Field
The region around a magnet where its force can be felt is called the magnetic field.

Magnetic Field Lines (Fig. 11.16):

• Definition: These are imaginary lines used to represent the direction and strength of a magnetic field.
• Properties:
  1. They are closed loops.
  2. Outside the magnet, their direction is always from the North pole to the South pole.
  3. Where the lines are closer together (at the poles), the magnetic field is stronger.
• How to Draw Field Lines (Experiment):
  1. Place a bar magnet on a piece of paper.
  2. Place a magnetic compass near the North pole.
  3. Put a dot on the. paper where the north tip of the compass needle points.
  4. Move the compass so its south tip is at the dot you just made.
  5. Repeat this process, making new dots, until you reach the South pole.
  6. Connect the dots to draw a single magnetic field line.

ഒരു കാന്തത്തിന് ചുറ്റും അതിന്റെ ശക്തി (ആകർ ഷണ/വികർഷണ ബലം അനുഭവപ്പെടുന്ന മേഖല യാണ് കാന്തിക മണ്ഡലം (Magnetic Field), ഈ കാന്തിക മണ്ഡലത്തെ ചിത്രീകരിക്കാൻ ഉപയോഗി ക്കുന്ന സാങ്കൽപ്പിക രേഖകളാണ് കാന്തിക മണ്ഡല രേഖകൾ (Magnetic Field Lines). ഈ രേഖകൾ കാന്തത്തിന് പുറത്ത് എപ്പോഴും നോർത്ത് പോളിൽ നിന്ന് ആരംഭിച്ച് സൗത്ത് പോളിൽ അവസാനിക്കുന്നു.

Magnetic Field Strength and Magnetic Flux Density
These terms describe how strong a magnetic field is.

Magnetic Field Strenth

This is how strong the magnet’s influence is. The iron filing experiment (Fig. 11.19) shows that the magnetic field strength is greatest at the poles and gets weaker as you move away.

Magnetic Flux ((കാന്തിക ഫ്ളക്സ്))

• Definition: “The total number of magnetic field lines passing normally (perpendicularly) through a given surface”.

• If the size of the flat surface in Fig 11.18 increases, the magnetic flux passing through it will also increase.

Magnetic Flux Density (കാന്തിക ഫ്ളക്സ് ഡെൻസിറ്റി)

• Definition: “The number of magnetic field lines passing normal through a unit area…”.
• This is a measure of how concentrated or dense the field lines are.
• Key Relationship: Magnetic flux density is higher where the magnetic field strength is more. Since the field strength is greatest at the poles (where iron filings stick the most), the poles of a magnet have the highest magnetic flux density.
• മാഗ്നറ്റിക് ഫ്ളക്സ് ഒരു പ്രതലത്തിലൂടെ ലംബ മായി കടന്നുപോകുന്ന കാന്തിക മണ്ഡല രേഖക ളുടെ ആകെ എണ്ണമാണ് (Total number) ഫ്ളക്സ്.
• മാഗ്നറ്റിക് ഫ്ളക്സ് ഡെൻസിറ്റി: ഒരു നിശ്ചിത വിസ്തീർണ്ണത്തിൽ (Unit Area) എത്രമാത്രം മണ്ഡലരേഖകൾ ഉണ്ട് (അവയുടെ ‘തിക്ക്’. ‘അ ടുപ്പം’) എന്നതാണ് ഫ്ളക്സ് ഡെൻസിറ്റി.
• കാന്തത്തിന്റെ ശക്തി (Strength) ഏറ്റവും കൂടു തലുള്ളത് ധ്രുവങ്ങളിൽ (poles) ആണ്. ഇവിടെ കാന്തിക മണ്ഡലരേഖകൾ വളരെ അടുത്തടുത്താ ണ് സ്ഥിതിചെയ്യുന്നത്. അതിനാൽ, കാന്തിക ശ ക്തി എവിടെയാണോ കൂടുതൽ, അവിടെ ഫ്ളക് സ് ഡെൻസിറ്റിയും കൂടുതലായിരിക്കും.

Magnetic Induction (കാന്തിക പ്രവേശനം)

This is the phenomenon of making a temporary magnet without touching it.

• Definition: “The phenomenon of a magnetic substance (like an iron pin) acquiring magnetism due to the presence of a magnet is known as Magnetic Induction”.
• The magnetism the substance (pin) gets is called Induced Magnetism.

Polarity of Induced Magnetism:

• The polarity of the induced magnet is fixed:
  • Unlike polarity develops at the nearer end.
  • Like polarity develops at the farther end.
• Example (Fig 11.21): The permanent magnet’s North pole (N) is near the pin.

• • The head of the pin (nearer end) gets the unlike pole: South pole (S).
  • The tip of the pin (farther end) gets the like pole: North pole (N).

ഒരു കാന്തത്തിന്റെ സാന്നിധ്യം (presence) മൂലം മറ്റൊരു കാന്തിക വസ്തുവിന് (magnetic substance, e.g., ആണ്) താൽക്കാലികമായി കാന്തശ ക്തി ലഭിക്കുന്ന പ്രതിഭാസമാണ് മാഗ്നറ്റിക് ഇൻഡക്ഷൻ.

പ്രത്യേകത: കാന്തത്തിന്റെ ഏത് ധ്രുവമാണോ അടു ത്തു കൊണ്ടുവരുന്നത്, അതിന് വിപരീത ധ്രുവം (unlike pole) ആയിരിക്കും ആണിക്ക് അറ്റത്ത് ലഭി ക്കുക. ആണിക്ക് മറ്റേ അറ്റത്ത് കാന്തത്തിന്റെ അതേ ധ്രുവം (like pole) ആയിരിക്കും ലഭിക്കുക.

Properties of Magnetic Materials (Soft Iron & Steel)
Different materials react to magnetic fields differently.

• Experiment (Fig 11.22 & 11.23):

• Soft Iron (പച്ചിരുമ്പ്): Gets magnetized easily when placed near a magnet. But when the magnet is removed, it quickly loses its magnetism.
• Steel (ഉരുക്ക്): Takes more time to get magnetised. However, even after the magnet is removed, it does not lose its magnetism quickly.
  This leads to four important properties:

Susceptibility

• Definition: The ability of magnetic materials to get magnetised due to the influence of an external magnetic field.
• Soft Iron has greater susceptibility.

Retentivity

• Definition: The ability to retain the magnetism.
• Steel has greater retentivity.

Permeability

• Definition: The ability of a substance to pass magnetic field lines through it.
• Soft Iron has a high permeability.

Soft Iron VS Steel (പച്ചിരുമ്പും ഉരുക്കും)

Material	Susceptibility (പെട്ടെന്ന് കാന്തമാകും)	Retentivity (കാന്ത ശക്തി നിലനിർത്തും)	Use (ഉപയോഗം)
Soft Iron	High	Low	Temporary magnets (e.g., Electromagnets)
Steel	Low	High	Permanent magnets

Applications:

• Soft Iron is suitable for making temporary magnets (like electromagnets) because of its high susceptibility and low retentivity.
• Steel is suitable for making permanent magnets because of its high retentivity.
• Magnetic Shielding: A compass placed inside a soft iron box will not show direction because soft iron’s high permeability forces the Earth’s magnetic field lines to pass through the box rather than the in-side, shielding the compass.

Electromagnets വൈദ്യുതകാന്തങ്ങൾ

• Definition: A temporary magnet made by passing electricity through an insulated wire coiled around a soft iron core.
• Property: Only magnetic when the cur¬rent is on.
• Uses: Electric bells, loudspeakers, MRI machines.
• Increasing Strength: You can make an electromagnet stronger by:
  1. Increasing the number of turns in the coil (ചുറ്റുകളുടെ എണ്ണം കൂട്ടുക).
  2. Increasing the strength of the current (വൈദ്യുതിയുടെ ശക്തി കൂട്ടുക).
  3. Increasing the cross-sectional area of the soft iron core (പച്ചിരുമ്പിന്റെ കനം കൂട്ടുക).

ഒരു പച്ചിരുമ്പ് കോറിന് (soft iron core) ചുറ്റും കവചിത ചാലകം (insulated wire) ഉപയോഗിച്ച് വൈദ്യുതി കടത്തിവിടുമ്പോൾ നിർമ്മിക്കപ്പെടുന്ന താൽക്കാലിക കാന്തങ്ങളാണ് വൈദ്യുതകാന്തങ്ങൾ. വൈദ്യുതി നിലയ്ക്കുമ്പോൾ ഇവയുടെ കാന്തശ ക്തി നഷ്ടപ്പെടുന്നു.

Object	Charge to be gained	Suitable charging method
Metal sphere	Positive
Metal sphere	Negative

Answer:

Object	Charge to be gained	Suitable charging method
Metal sphere	Positive	Charging by Conduction
Metal sphere	Negative	Charging by Induction

Question 2.
At petrol pumps, the nozzle used for filling petrol is earthed. Why?
Answer:
To prevent sparks and fire.

• Reason: As petrol (a highly flammable liquid) flows quickly through the pipe and nozzle, friction can build up a significant amount of static electricity on both the nozzle and the vehicle.
• If this static charge becomes large enough, it can discharge as a spark to the car’s body.
• A spark in the presence of petrol fumes will cause a dangerous fire or explosion.
• Earthing the nozzle provides a continuous path for any static charge to flow safely into the ground, neutralizing it and preventing any sparks from forming.

Question 3.
A plastic pen can be easily charged by rubbing it on hair. However, this is not possible when a steel spoon is used instead of this. What is the reason?
Answer:
The reason is the difference between insulators and conductors.

• Plastic Pen: Plastic is an insulator). When you rub it, the static charge builds up on its surface and stays there because it cannot flow easily.
• Steel Spoon: Steel is a conductor. Your hand and body are also conductors. When you rub the steel spoon, charges are indeed separated. However, they immediately flow through the spoon, through your hand and body, and safely into the Earth.
• Because the charge cannot accumulate, the spoon remains neutral and doesn’t show any static electric effects.

Question 4.
If a positively charged metal object comes into contact with another negatively charged metal object of equal magnitude, determine the charge on both objects.
Answer:
The charge on both objects will be zero (0). They will become electrically neutral.

When the two objects touch, the excess electrons from the negatively charged object flow to the positively charged object, which has a corresponding deficit of electrons. Since the charges were of equal magnitude, this transfer perfectly balances the charges, resulting in no net charge on either object. This is called neutralization.

Question 5.
Poorly earthed lightning conductors are more harmful than beneficial. What is the reason?
Answer:
A lightning conductor is designed to attract a lightning strike by using induction at its sharp point. Its only job is to provide a safe, low-resistance path for the massive electrical charge to go directly into the Earth.

• If it is “poorly earthed” (meaning the connection to the ground is broken, loose, or not deep enough), it will still attract the lightning strike.
• However, the charge will not have a safe path to the ground. Instead, the lightning will find the next easiest path, which will be the building itself (through its metal pipes, wiring, or concrete).
• This will cause a massive surge of electricity through the building, leading to major fires, explosions, and destruction. A poorly earthed rod essentially invites the lightning to strike the building and provides no protection.

Question 19.
What charge do balloons gain when rubbed with wool?
Positive / Negative
Answer:
Negative charge (Rubber gains electrons from wool).

Question 20.
What charge does the wool gain after rubbing?
Positive / Negative
Answer:
Positive. (Wool loses electrons to the balloons).

Question 21.
Is attraction or repulsion the most suitable indication to confirm the charge of an object?
Answer:
Repulsion

Question 22.
If two objects attract each other, can it be confirmed that both are charged? What if they repel?
Answer:
If they attract, it cannot be confirmed that both are charged (since a charged object attracts a neutral object). If they repel, it can be confirmed that both are charged with the same type of charge

Question 23.
Can static electricity light up a bulb?
Answer:
No. Static electricity means the charge “remains in the same place.” A light bulb needs a continuous flow of charge (electric current) to light up. A static discharge (like a small spark) is a very brief flow and is not enough to light a standard bulb.

The method of charging a metal sphere using a negatively charged glass rod is shown in the picture. Observe the picture and write down the different steps.

Answer:

Step	Action	Short Result
1. Induction	Bring the negatively charged rod near the neutral sphere.	Positive charge is attracted to the near side, negative charge is repelled to the far side.
2. Earthing	Touch the far side of the sphere to the ground while the rod is still near.	Repelled negative charge flows into the Earth.
3. Remove Earthing	Remove the ground connection first.	The positive charge is trapped on the sphere.
4. Remove Rod	Remove the charged rod.	The trapped positive charge spreads evenly, leaving the sphere permanently positively charged.

Question 31.
What is the charge given to the toner particles here?
Answer:
Negative (-).

Question 32.
What causes the toner particles to stick to the drum as it rotates?
Answer:
The negative toner is attracted to the positive areas on the drum (where the image is).

Question 33.
What is the charge given to the paper?
Answer:
Negative

Question 34.
What is the charge of the paint droplets?
Answer:
Positive (+) (A stronger positive charge than the drum).

Question 35.
Why do the toner particles stick to the paper?
Answer:
The negative toner is more strongly attracted to the positively charged paper and transfers from the drum to the paper.

Question 36.
Image 10.16 (Person touching a doorknob): Discuss the reasons for small sparks.

Answer:
Friction (e.g., from walking) causes a static charge to accumulate on the person’s body. When the person touches the metallic doorknob (grounded conductor), the stored charge discharges rapidly, creating a spark as it flows to the Earth.

Question 37.
Damage to Electronic Components (Fig. 10.17)

Answer:
Yes, the rapid flow of high voltage from the human body (Electrostatic Discharge or ESD) can damage or destroy the delicate, small-scale electronic components in the circuit.

Question 38.
Charged Pen/Scale Touched to the Ground
Answer:
It will no longer attract pieces of paper. The object becomes neutralized because the Earth, being an “electron bank,” transfers electrons to or from the object.

Question 39.
Neutralization by Earthing (Fig. 10.19 a & 10.19b)

Answer:

• Negatively Charged Object (Excess Electrons): The excess electrons flow from the object to the Earth (down arrow).
• Positively Charged Object (Deficient Electrons): Electrons flow from the Earth to the object (up arrow).

Textbook Page No : 177 & 178

Child on Slide (Fig 10.20):

Question 40.
How did the charge accumulate in the hair?
Answer:
Through friction between the child’s body/hair and the plastic slide.

Question 41.
Can you suggest a method to neutralise the charge?
Answer:
Earthing. The child can touch the ground, or a metal part of the slide structure that is connected to the ground.

Question 42.
Write about the earthing mechanism in dangerous situations.
Answer:
In situations where static electricity is dangerous (e.g., handling sensitive electronics), earthing is used to neutralize accumulated charge. The Earth acts as an “electron bank” and allows any excess charge on the object/person to flow safely to the ground. This prevents a sudden, damaging Electrostatic Discharge (ESD).

Question 43.
What will happen if a negatively charged rod is placed near a metal sphere?
Answer:
A redistribution of charges takes place in the metal sphere, a process called electrostatic induction.

Textbook Page No : 179 & 180

Question 44.
The metal sphere is earthed. Now, remove the earthing and then the charged rod. Won’t the metal sphere acquire a permanent charge?
Answer:
Yes, the sphere will acquire a permanent positive charge. This is achieved by:

1. Earthing while the rod is nearby: Repelled electrons flow from the sphere into the Earth.
2. Removing the earthing (trapping the positive charge).
3. Removing the rod (allowing the positive charge to spread).

Question 45.
Write down the parts of an electroscope.
Answer:

• Metal sphere
• Glass jar
• Metallic conductor (Rod)
• Golden leaves (or Aluminum foil leaves)

Question 46.
What do you observe? What is the reason?
Answer:
The aluminum foil leaves will diverge (move apart).
Reason: The charged rod induces the same type of charge onto both leaves through induction. Since like charges repel, the leaves push each other apart.

Question 47.
Bring a neutral object nearby. Do the leaves diverge now?
Answer:
No, neutral objects cause no movement in the leaves.

Question 48.
When plate A is positively charged, observe the induction of charges in B. What if plate B is earthed?
Answer:

• Induction on B: Plate A’s positive charge attracts negative charges to the near side of B and repels positive charges to the far side of B.
• Plate B Earthed: Electrons flow up from the Earth to neutralize the repelled positive charges on plate B, trapping the net negative charge on the near side.

Question 49.
Draw the distribution of charges (Fig. 10.28).

Answer:

1. Plate A: Positively charged (+).
2. Plate B: Negatively charged (-).

Textbook Page No : 181 & 182

Question 50.
How are charges distributed on a metal surface?
Answer:

1. In electrical conductors, the charge is distributed only on the surface.
2. The amount of charge will be very high at the sharp edges (or points) of the conductor.

Question 51.
How does the cloud get charged?
Answer:
Various air currents cause friction (rubbing) between ice crystals and water droplets, leading to the accumulation of electric charges in the clouds.

Question 52.
What types of charges are accumulated in clouds?
Answer:
Both positive and negative charges.

Question 53.
Why are the objects on Earth oppositely charged?
Answer:
Due to electrostatic induction. The highly charged cloud induces an opposite charge on objects directly below it on the Earth’s surface.

Question 54.
What all can we do to protect ourselves from lightning?
Answer:

• Do not seek shelter under tall or isolated trees.
• Do not attempt to operate electrical appliances.
• Stay inside a fully enclosed building or a car.

Question 55.
Why is a positive charge induced at the sharp points of the lightning conductor when clouds are negative?
Answer:
Reason: The high concentration of charge at sharp points and the principle of induction cause the opposite charge (positive) to be strongly induced and discharged into the atmosphere.

Question 56.
What if the clouds have a positive charge?
Answer:
A negative charge will be induced at the sharp points of the lightning con¬ductor, following the rule that opposite charges are induced.

Question 57.
First Aid if a Person is Struck by Lightning
Answer:

• Lay the person flat in a well-ventilated area.
• Massage the entire body to warm it up (to help with circulation).
• Provide artificial respiration
• Apply intermittent pressure on the chest (CPR) if you are trained.
• Call for emergency medical help immediately.

Class 8 Basic Science Chapter 10 Question Answer Extended Activities

Question 1.
Seat a child on a plastic chair in such a way that both their feet do not touch the ground. Charge the chair using a woolen cloth. Let the child hold one terminal of a Neon bulb, and make another person touch the other terminal. What do you observe? Write down the observations.
Answer:
Setup: A child sits on a plastic chair (insulator) with feet off the ground (isolated from Earth). You charge the plastic chair by rubbing it with wool. This charges the child’s body by induction. (For example, if the chair becomes negative, it will repel electrons in the child’s body to their hands/head).

Observation: When the child holds one terminal of the neon bulb and another person (who is earthed/standing on the ground) touches the other terminal, the neon bulb will flash briefly.

Reason: The child has a high static charge (potential). The other person is at Earth’s potential (zero). The neon bulb creates a path for the static charge to discharge from the child, through the bulb, to the other person, and into the Earth. This tiny, quick flow of current is enough to make the neon gas inside the bulb light up for a moment.

Question 2.
Prepare and present a seminar on Van de Graff generator.
Answer:
Van de Graaff Generator

A Van de Graaff generator is a machine designed to build up an extremely high static electric charge on a large metal sphere. It works by using a moving belt to physically carry charges from a source at the bottom and deposit them onto the sphere at the top. It is famously used in science demonstrations to make a person’s hair stand on end when they touch it (for the same reason the balloon makes hair stand up, just on a much larger scale!).

Static Electricity Class 8 Notes

Class 8 Basic Science Static Electricity Notes Kerala Syllabus

Static Electricity (സ്ഥിത വൈദ്യുതി)
When you rub a balloon on dry hair, your hair is attracted to the balloon. Similarly, a plastic pen rubbed on hair can attract small pieces of paper. This ability of objects to attract after being rubbed is due to electric charge.

Static electricity is the result of an imbalance of electric charges on the surface of an object.

“If electric charge remains in the same place without being able to flow, such electricity is called static electricity.”
Example: Rubbing a balloon on dry hair causes the hair to be attracted to the balloon.
ഒരു വസ്തുവിൽ ഉണ്ടാകുന്ന വൈദ്യുത ചാർജു കൾ ഒരിടത്ത് തന്നെ തങ്ങിനിൽക്കുന്നതിനെയാണ് സ്ഥിത ർജുകൾക്ക് ആകർഷിക്കാനുള്ള കഴിവുണ്ട്. ഉദാ ഹരണത്തിന്, ഒരു പ്ലാസ്റ്റിക് പേന മുടിയിൽ ഉര സി ചെറിയ കടലാസ് കഷണങ്ങൾക്ക് അടുത്തേ ക്ക് കൊണ്ടുവരുമ്പോൾ അവ ആകർഷിക്കപ്പെടു ന്നു. ഇത് സ്ഥിത വൈദ്യുതി മൂലമാണ്.

The Atom (ആറ്റം)
All matter is made of tiny particles called atoms. The charges we observe come from the particles inside the atom.

An atom has two main parts:
1. Nucleus (the center): Contains:
Protons (have a positive charge ‘+’)
Neutrons (have no charge / are neutral)

2. Orbits (the paths around the nucleus): Contain:
Electrons (have a negative charge ‘-‘)

An object gets charged by the transfer of electrons. Protons do not move.
എല്ലാ പദാർത്ഥങ്ങളും ആറ്റങ്ങൾ എന്നറിയപ്പെടുന്ന അതിസൂക്ഷ്മ കണങ്ങളാൽ നിർമ്മിതമാണ്. ഒരു ആറ്റത്തിന്റെ കേന്ദ്രഭാഗമാണ് ന്യൂക്ലിയസ്. ഇതിൽ പോസിറ്റീവ് ചാർജുള്ള പ്രോട്ടോണുകളും (‘+’) ചാർജില്ലാത്ത ന്യൂട്രോണുകളും അടങ്ങിയിരിക്കു ന്നു. ന്യൂക്ലിയസിന് ചുറ്റുമുള്ള പാതകളിൽ നെഗ റ്റീവ് ചാർജുള്ള ഇലക്ട്രോണുകൾ (‘-‘) കറങ്ങി ക്കൊണ്ടിരിക്കുന്നു.

• Loses electrons (e-) → Positively charged
  (ഇലക്ട്രോൺ നഷ്ടപ്പെട്ടാൽ പോസിറ്റീവ് ചാർജ്).
• Gains electrons (e-) → Negatively charged
  (ഇലക്ട്രോൺ നേടിയാൽ നെഗറ്റീവ് ചാർജ്).

Electric Charge

• Electrically Neutral Object: Contains an equal number of protons and electrons (net charge is zero).
• Positively Charged Object: Has a deficiency of electrons (more protons than electrons).
• Negatively Charged Object: Has an excess of electrons (more electrons than protons).

Characteristics of Electric Charges
1. Like Charges Repel: Objects carrying the same type of charge (e.g., two positive charges or two negative charges) will push each other away.

when two balloons are rubbed with the same piece of wool, they both gain the same type of charge (negative charge, as rubber gains electrons from wool). When brought near each other, they move apart.
സജാതീയ ചാർജുകൾ (Like Charges): ഒരേത രം ചാർജുകൾ (പോസിറ്റീവും പോസിറ്റീവും, അ ല്ലെങ്കിൽ നെഗറ്റീവും നെഗറ്റീവും) പരസ്പരം വികർ ഷിക്കുന്നു. (ഉദാ: കമ്പിളിയിൽ ഉരസിയ രണ്ട് ബല ണുകൾ പരസ്പരം അകന്നുപോകുന്നു).

2. Unlike Charges Attract: Objects carrying opposite charges (one positive and one negative) will pull each other closer.
The wool (which lost electrons) is now positively charged. The balloon (which gained electrons) is negatively charged. When the wool is brought near the balloon, the balloon is attracted to it.

സജാതീയ ചാർജുകൾ (Like Charges): ഒരേത രം ചാർജുകൾ (പോസിറ്റീവും പോസിറ്റീവും, അ ല്ലെങ്കിൽ നെഗറ്റീവും നെഗറ്റീവും) പരസ്പരം വികർ ഷിക്കുന്നു. (ഉദാ: കമ്പിളിയിൽ ഉരസിയ രണ്ട് ബല ണുകൾ പരസ്പരം അകന്നുപോകുന്നു).

3. Charged Objects Attract Neutral Objects: A charged object can induce temporary charge separation in a neutral object, resulting in a net attractive force.

A charged object (like the acrylic sheet) can also attract a neutral, uncharged object (like the thermocol balls).

ചാർജുള്ള ഒരു വസ്തുവിന് ചാർജില്ലാത്ത (netural) വസ്തുക്കളെയും ആകർഷിക്കാൻ കഴിയും.

A charged object can attract a neutral object. Therefore, repulsion is the sure test to confirm if an object is charged.
ആകർഷണം (attraction) ചാർജുള്ള വസ്തു വും ചാർജില്ലാത്ത വസ്തുവും തമ്മിലും നടക്കാം. എന്നാൽ വികർഷണം (repulsion) ഒരേതരം ചാർജുള്ള വസ്തുക്കൾ തമ്മിൽ മാത്രമേ നടക്കൂ. അതിനാൽ, ചാർജ് ഉണ്ടോ എന്ന് ഉറപ്പിക്കാനുള്ള മാർഗ്ഗം വികർഷണമാണ്.

Methods of Charging (ചാർജ് ചെയ്യുന്ന രീതികൾ)

1. Charging by Friction (ഘർഷണം): Charging by rubbing two objects together (e.g., glass rod and silk).
2. Charging by Conduction (ചാലകം വഴിയുള്ള ചാർജിംഗ്)
   • “Charging by conduction is the method of charging an object by direct physical contact with a charged object.”
   • The object gets the SAME charge. (തൊടുമ്പോൾ, അതേ ചാർജ് ലഭിക്കുന്നു.)
3. Charging by Induction (പ്രവേശനം):
   • “Charging by induction is the method of charging an object without direct physical contact of a charged object.”
   • The object gets the OPPOSITE charge. (തൊടാതെ അടുത്ത് കൊണ്ടുവരുമ്പോൾ, വിപ രീത ചാർജ് ലഭിക്കുന്നു).

Applications of Static Electricity (സ്ഥിത വൈദ്യുതിയുടെ ഉപയോഗങ്ങൾ)

We can use the properties of static electricity (like charges repel, unlike charges attract) in useful ways.
A. Electrostatic Spray Painting
This method is used in workshops to paint vehicles efficiently.

□ Process:

1. The nozzle of the spray gun gives the tiny paint droplets a negative charge (-).
2. The car body (or object to be painted) is given the opposite positive charge (+).

□ Result: Because unlike charges attract, the negative paint droplets are strongly attracted to the positive car body. This method reduces paint waste and ensures the paint covers the surface evenly, even “wrapping around” edges.
‘വിപരീത ചാർജുകൾ ആകർഷിക്കും’ (Unlike charges attract) എന്ന തത്വം ഇവിടെ ഉപ യോഗിക്കുന്നു. പെയിന്റ് കണങ്ങൾക്ക് നെഗറ്റീവ് ചാർജും കാറിന് പോസിറ്റീവ് ചാർജും നൽകുന്നു. ഇത് പെയിന്റ് പാഴാകാതെ കാറിൽ കൃത്യമായി പ റ്റിപ്പിടിക്കാൻ സഹായിക്കുന്നു.

B. Photocopier Machine
Photocopiers also use static electricity to create a copy.

□ Process:

1. A special drum inside is given a positive charge (+) in the exact shape of the letters or images on the original paper.
2. The toner (a fine black powder) is given a negative charge (-).
3. The negative toner is attracted to the positive areas of the drum.
4. A sheet of paper is then given a stronger positive charge (+) than the drum.
5. The negative toner is pulled from the drum onto the paper because of this stronger attraction.
6. Finally, the paper is heated to melt the toner and make the copy permanent.

Situations where static electricity is harmful (സ്ഥിത വൈദ്യുതി ദോ ഷകരമാകുമ്പോൾ)

While useful, a sudden discharge of static electricity can be a problem.

Electric Shock : When you walk on a carpet or slide across a car seat, friction can build up a large static charge on your body. When you touch a metal doorknob or the car door, this charge suddenly discharges as a spark, giving you a small, sharp shock.

Damaging Electronics : This same sudden discharge (spark) is very dangerous for sensitive electronic components, like those inside a mobile phone or computer. A person with a static charge on their hand can permanently damage a circuit board just by touching it. This is why technicians wear antistatic gloves.
ഘർഷണം മൂലം നമ്മുടെ ശരീരത്തിൽ സ്ഥിത വൈദ്യുതിയുടെ ചാർജ് അടിഞ്ഞുകൂടാം. ഇത് ഒരു ലോഹ വസ്തുവിൽ തൊടുമ്പോൾ ഒരു ‘സ്പാ ർക്ക്’ ആയി ഡിസ്ചാർജ് ചെയ്യപ്പെടുന്നു (ഇതാണ് നമുക്ക് ചെറിയ ഷോക്ക് അടിക്കുന്നത്. ഈ ഡി സാർജ് ഇലക്ട്രോണിക് ഉപകരണങ്ങളിലേക്കാ ണെങ്കിൽ, അത് ആ ഉപകരണത്തെ നശിപ്പിക്കാൻ സാധ്യതയുണ്ട്.

Earthing (എർത്തിംഗ്) grounding
Earthing is the process of connecting a charged object to the Earth to neutralize it.

“The Earth is an electron bank. Due to its size and conductivity, the Earth can donate and receive electrons. Therefore, charged objects are neutralised when earthed.”

How it works:

• A positively charged object pulls electrons (e-) from the Earth.
• A negatively charged object pushes excess electrons (e-) to the Earth.

• Petrol pump nozzles are earthed to prevent sparks (from friction) that could cause a fire.

ചാർജുള്ള ഒരു വസ്തുവിനെ ഭൂമിയുമായി ബന്ധി പ്പിച്ച് അതിനെ നിർവീര്യമാക്കുന്ന (neturalize) പ്രക്രിയയാണ് എർത്തിംഗ്.

പോസിറ്റീവ് ചാർജുള്ള വസ്തുവിനെ എർത്ത് ചെ യുമ്പോൾ, ഭൂമിയിൽ നിന്ന് ഇലക്ട്രോണുകൾ ആ വസ്തുവിലേക്ക് പ്രവഹിച്ച് അതിനെ നിർവീര്യമാ ക്കുന്നു.

നെഗറ്റീവ് ചാർജുള്ള വസ്തുവിനെ എർത്ത് ചെ യുമ്പോൾ, ആ വസ്തുവിൽനിന്നും അധികമുള്ള ഇലക്ട്രോണുകൾ ഭൂമിയിലേക്ക് പ്രവഹിക്കുന്നു.

Charging by Induction (പ്രവേശനം വഴിയുള്ള ചാർജിംഗ്)



Process (Figs 10.22, 10.23, 10.24):

1. Step 1 : A negatively charged rod is brought near (not touching) a neutral metal sphere.
2. Step 2 : (Electrostatic Induction): The negative rod repels the free electrons (-) in the sphere, causing them to move to the far side. The side of the sphere near the rod becomes positive (+) due to a lack of electrons. This separation is called redistribution of charges.
3. Step 3: While the rod is still held nearby, the sphere is earthed. The repelled electrons get an escape path and flow from the sphere into the Earth.
4. Step 4: The earthing is removed first. The sphere is now left with an overall positive charge, which is still held near the rod.
5. Step 5: The rod is removed. The positive charges (which were crowded near the rod) now spread out evenly over the surface of the sphere.
   • The sphere has become permanently positively charged. Notice that the charge it gained is opposite to the charge of the rod used (negative rod → positive sphere).

പ്രേരണ മുഖേനയുള്ള ചാർജിംങ് : ചാർജുള്ള ഒരു വസ്തുവിനെ (rod) മറ്റൊരു വസ്തുവിന്റെ (sphere) അടുത്തേക്ക് (തൊടാതെ) കൊണ്ടുവന്ന് ചാർജ് ചെയ്യുന്ന രീതിയാണിത്.

1. നെഗറ്റീവ് ദണ്ഡ് അടുത്ത് വരുമ്പോൾ, ഗോള ത്തിലെ ഇലക്ട്രോണുകൾ വികർഷിച്ച് ദൂരേക്ക്മാറുന്നു.
2. ഈ സമയത്ത് ഗോളത്തെ എർത്ത് ചെയ്യു മ്പോൾ, ഈ ഇലക്ട്രോണുകൾ ഭൂമിയിലേക്ക് ഒഴുകിപ്പോകുന്നു.
3. ആദ്യം എർത്തിംഗ് മാറ്റുക. അതിനുശേഷം ദണ്ഡ് മാറ്റുക.
4. ഇപ്പോൾ ഗോളത്തിന് സ്ഥിരമായ പോസിറ്റീവ് ചാർജ് (ഇലക്ട്രോണുകളുടെ കുറവ് ലഭിക്കു ന്നു. ഇൻഡക്ഷൻ വഴി ലഭിക്കുന്ന ചാർജ്, ഉപ യോഗിച്ച ദണ്ഡിന്റെ ചാർജിന് വിപരീതമായി രിക്കും.

Electroscope
An electroscope is a scientific instrument used to detect the presence of electric charge on an object.

Parts (Fig 10.25): It consist’s of a metal sphere (or disc) on top, a metal rod, and two very thin, lightweight “leaves” (often gold or aluminium foil) at the bottom, all enclosed in a glass jar to protect from air currents.

How it Works (Working Principle):

1. Bring a charged object (e.g., a positively charged rod) near the top metal sphere.
2. By induction, electrons (-) from the leaves and rod are attracted upwards towards the positive rod.
3. This leaves both the leaves at the bottom with a deficit of electrons, so both leaves become positively charged.
4. Since like charges repel, the two positive leaves move apart, or “diverge”.
5. If you bring a neutral object near the electroscope, nothing happens because it does not cause the charges to separate.

How it Works (Fig 10.27, 10.28): A simple capacitor consists of two metal plates placed very close together, separated by an insulator.

• When one plate (A) is given a charge (e.g., positive), it induces an opposite charge (negative) on the near side of the second plate (B).
• If plate B is earthed, the repelled positive charges flow to the Earth, “locking” the negative charges on plate B. This allows even more positive charge to be stored on plate A.
  • Capacitance: The ability of a capacitor to store charge is called capacitance. Its SI unit is the Farad (F).
  • Dielectric: The insulating material between the plates (like paper, air, or polyester) is called a dielectric. It helps to increase the capacitance.

വൈദ്യുത ചാർജ് സംഭരിച്ചുവെക്കാൻ (store eletcric charge) ഉപയോഗിക്കുന്ന ഒരു ഉപകരണമാ ണ് കപ്പാസിറ്റർ. ഇതിന്റെ ചാർജ് സംഭരിക്കാനുള്ള കഴിവിനെ കപ്പാസിറ്റൻസ് എന്ന് പറയുന്നു. ഇതി ന്റെ യൂണിറ്റ് ഫാരഡ് (F) ആണ്. ഫാനുകളിലും മോട്ടോറുകളിലും മറ്റ് ഇലക്ട്രോണിക് ഉപകരണങ്ങ ളിലും ഇത് വ്യാപകമായി ഉപയോഗിക്കുന്നു.

Distribution of Electric Charges ((ചാർജുകളുടെ വിതരണം))
Where do charges stay on a conductor?

1. On the Surface: In electrical conductors, charge is always distributed only on the outer surface.
2. At Sharp Edges: The amount of charge (charge density) will be much higher at the sharp edges or pointed parts of a conductor.

ഒരു ചാലകത്തിന് (conductor) ചാർജ് നൽകു മ്പോൾ, ആ ചാർജ് അതിന്റെ പ്രതലത്തിൽ (surface) മാത്രമാണ് വിതരണം ചെയ്യപ്പെടുന്നത്. ചാ ലകത്തിന്റെ കൂർത്ത അഗ്രങ്ങളിൽ (sharp edges) ചാർജിന്റെ അളവ് വളരെ കൂടുതലായിരിക്കും. (ഇടിമിന്നൽ രക്ഷാചാലകം അഥവാ lightning conductor പ്രവർത്തിക്കുന്നത് ഈ തത്വമനുസരി ച്ചാണ്).

Lightning and Lightning Conductor (ഇടിമിന്നലും രക്ഷാചാലകവും)
Lightning
Lightning is a massive-scale natural example of static electricity and electrostatic discharge.
How does lightning occur?

1. Charging the Clouds: Cloud friction generates massive static charge (+ & -).
2. Induction on Earth: Charged cloud induces opposite charge on the Earth’s surface.
3. Electric Discharge: WExcessive charge discharges through the air to the Earth as a giant spark (lightning).
1. മേഘങ്ങളിൽ ഘർഷണം (friction) മൂലം വൻതോതിൽ വൈദ്യുത ചാർജ് (പോസിറ്റീവും നെഗറ്റീവും) ഉണ്ടാകുന്നു.
2. ചാർജ് ചെയ്ത മേഘം, ഇൻഡക്ഷൻ (induction) വഴി ഭൂമിയുടെ ഉപരിതലത്തിൽ വിപരീത ചാർജ് (opposite charge) ഉണ്ടാക്കുന്നു.
3. ചാർജിന്റെ അളവ് വളരെ കൂടുമ്പോൾ, അത് വാ യുവിലൂടെ ഭൂമിയിലേക്ക് ഒരു ഭീമൻ സ്പാർക്കാ യി ഡിസാർജ് ചെയ്യുന്നു. ഇതാണ് ഇടിമിന്നൽ.
□ Charge Distribution: On a conductor, charge stays on the surface and is most concentrated at sharp points. (കുർത്ത അഗ്രങ്ങളിൽ ചാർജ് കേന്ദ്രീകരിക്കുന്നു).

Lightning Conductor (Arrester)
A metal rod installed on the top of tall buildings and connected by a thick wire to a metal plate deep in the ground.

• Function: It provides a safe, low-resistance path for the lightning strike’s current to flow directly into the Earth, protecting the structure from damage.
• Note: The charge naturally concentrates and discharges from the sharp points of the conductor, neutralizing the cloud’s charge gradually. A poorly earthed conductor is dangerous as it cannot safely handle the massive current.

Lightning Arrester vs. Lightning Conductor

• Lightning Conductor (രക്ഷാചാലകം) protects the building structure from a direct hit.
• Lightning Arrester is a different device used to protect the electrical system (like transformers at a KSEB substation, Fig 10.35) from sudden high-voltage surges caused by lightning.

Personal Safety Measures During Lightning

• Do not stand under tall, isolated trees.
• Do not touch electrical appliances or metallic objects.
• The safest places are inside a fully enclosed building or a car (the metal body acts as a Faraday cage).

First Aid for Lightning Strike

• If a person is struck, follow these steps:
• Lay the person flat in a Well-ventilated area.
• Massage the entire body to warm it up.
• Provide artificial respiration.
• Apply intermittent pressure on the chest.
