Assertion & Reason Questions
1
Assertion (A): Iron, nickel, and cobalt are magnetic materials.
Reason (R): Magnetic materials are those which get attracted towards a magnet.
Reason (R): Magnetic materials are those which get attracted towards a magnet.
Answer: (a)
Both A and R are true, and R is the correct explanation of A. Materials that are attracted to a magnet are called magnetic materials, and iron, nickel, and cobalt are classic examples.
2
Assertion (A): Wood and plastic are non-magnetic materials.
Reason (R): Non-magnetic materials are strongly repelled by magnets.
Reason (R): Non-magnetic materials are strongly repelled by magnets.
Answer: (c)
A is true, but R is false. Wood and plastic are non-magnetic because they are simply not attracted to magnets. They are not strongly repelled; repulsion is a property observed between like poles of two magnets.
3
Assertion (A): Maximum iron filings cling to the ends of a bar magnet when it is placed in them.
Reason (R): The magnetic strength is maximum at the poles, which are located at the ends of a magnet.
Reason (R): The magnetic strength is maximum at the poles, which are located at the ends of a magnet.
Answer: (a)
Both A and R are true, and R is the correct explanation of A. The poles of a magnet have the strongest magnetic pull, which is why most iron filings stick to the ends.
4
Assertion (A): A freely suspended bar magnet always comes to rest in the East-West direction.
Reason (R): The Earth itself behaves like a giant magnet.
Reason (R): The Earth itself behaves like a giant magnet.
Answer: (d)
A is false, but R is true. A freely suspended magnet always aligns itself in the North-South direction, not East-West, due to the Earth's magnetic field.
5
Assertion (A): A magnetic compass is used by sailors and navigators to find directions.
Reason (R): The compass needle is a small magnet that freely rotates and aligns itself in the North-South direction.
Reason (R): The compass needle is a small magnet that freely rotates and aligns itself in the North-South direction.
Answer: (a)
Both A and R are true, and R is the correct explanation of A. The compass works for navigation precisely because its magnetised needle consistently points towards the North-South direction.
6
Assertion (A): When the North pole of one magnet is brought near the North pole of another, they attract each other.
Reason (R): Like poles of magnets repel each other.
Reason (R): Like poles of magnets repel each other.
Answer: (d)
A is false, but R is true. Like poles (North-North or South-South) always repel each other; they do not attract.
7
Assertion (A): The North pole of a magnet attracts the South pole of another magnet.
Reason (R): Unlike poles of two magnets attract each other.
Reason (R): Unlike poles of two magnets attract each other.
Answer: (a)
Both A and R are true, and R is the correct explanation of A. It is a fundamental property of magnets that opposite (unlike) poles attract.
8
Assertion (A): Magnetite is considered a natural magnet.
Reason (R): Magnetite was first discovered by a shepherd named Magnes in ancient Greece.
Reason (R): Magnetite was first discovered by a shepherd named Magnes in ancient Greece.
Answer: (b)
Both A and R are true, but R is NOT the correct explanation of A. While the story of Magnes is historically associated with the discovery of magnetite, it does not scientifically explain why magnetite acts as a natural magnet.
9
Assertion (A): An iron strip can be converted into a magnet by rubbing it with a permanent magnet.
Reason (R): The rubbing must be done in a back-and-forth motion using both poles of the magnet.
Reason (R): The rubbing must be done in a back-and-forth motion using both poles of the magnet.
Answer: (c)
A is true, but R is false. To make a magnet, the iron strip must be rubbed in a single direction using only one pole of the permanent magnet, not back-and-forth.
10
Assertion (A): Magnets lose their magnetic properties if they are heated strongly.
Reason (R): Heating, hammering, or dropping from a height destroys the internal magnetic alignment inside a magnet.
Reason (R): Heating, hammering, or dropping from a height destroys the internal magnetic alignment inside a magnet.
Answer: (a)
Both A and R are true, and R is the correct explanation of A. Extreme physical shocks or high temperatures scramble the magnetic domains, causing the magnet to lose its properties.
11
Assertion (A): Bar magnets should be stored in pairs with their like poles on the same side.
Reason (R): Storing magnets improperly can cause them to lose their magnetic properties over time.
Reason (R): Storing magnets improperly can cause them to lose their magnetic properties over time.
Answer: (d)
A is false, but R is true. Bar magnets should be stored with their UNLIKE poles on the same side, separated by a piece of wood, to preserve their magnetism.
12
Assertion (A): Bar magnets are stored with two pieces of soft iron placed across their ends.
Reason (R): These soft iron pieces, called keepers, help in preserving the magnetic properties of the magnets.
Reason (R): These soft iron pieces, called keepers, help in preserving the magnetic properties of the magnets.
Answer: (a)
Both A and R are true, and R is the correct explanation of A. Soft iron keepers complete the magnetic circuit, preventing the magnets from losing their strength over time.
13
Assertion (A): Magnets can only be found in the shape of a rectangular bar.
Reason (R): Artificial magnets are made in different shapes such as horseshoe, cylindrical, and ball-ended.
Reason (R): Artificial magnets are made in different shapes such as horseshoe, cylindrical, and ball-ended.
Answer: (d)
A is false, but R is true. Magnets are not restricted to bar shapes; they are manufactured in many different shapes depending on their intended use.
14
Assertion (A): A magnet can be used to separate iron pins mixed with sand.
Reason (R): Iron is a magnetic material and gets attracted to the magnet, leaving the non-magnetic sand behind.
Reason (R): Iron is a magnetic material and gets attracted to the magnet, leaving the non-magnetic sand behind.
Answer: (a)
Both A and R are true, and R is the correct explanation of A. Magnetic separation works because the magnet only attracts the magnetic iron pins, easily pulling them out of the non-magnetic sand.
15
Assertion (A): If a bar magnet is broken into two halves, each half will have only one pole.
Reason (R): Magnetic poles always exist in pairs.
Reason (R): Magnetic poles always exist in pairs.
Answer: (d)
A is false, but R is true. You cannot isolate a single magnetic pole. If you break a magnet in half, each new piece will instantly have its own North and South poles.
16
Assertion (A): Not all coins are attracted to a magnet.
Reason (R): Coins made of brass or copper are non-magnetic materials and are not attracted to magnets.
Reason (R): Coins made of brass or copper are non-magnetic materials and are not attracted to magnets.
Answer: (a)
Both A and R are true, and R is the correct explanation of A. Since brass and copper do not possess magnetic properties, coins made purely of these metals will not stick to a magnet.
17
Assertion (A): Repulsion is the surest test for magnetism.
Reason (R): Both a magnet and a regular piece of magnetic material will attract the pole of another magnet, but only two magnets will repel each other.
Reason (R): Both a magnet and a regular piece of magnetic material will attract the pole of another magnet, but only two magnets will repel each other.
Answer: (a)
Both A and R are true, and R is the correct explanation of A. Because an unmagnetised piece of iron will attract both the North and South poles of a magnet, only repulsion can confirm that an object is actually a magnet itself.
18
Assertion (A): The dial of a magnetic compass is enclosed in a glass casing.
Reason (R): The glass casing prevents the wind from disturbing the magnetic needle while allowing us to read the directions.
Reason (R): The glass casing prevents the wind from disturbing the magnetic needle while allowing us to read the directions.
Answer: (a)
Both A and R are true, and R is the correct explanation of A. The transparent glass protects the sensitive needle from external air currents while keeping the dial visible.
19
Assertion (A): When a magnet is rubbed in soil, some dark particles may stick to it.
Reason (R): The dark particles sticking to the magnet are bits of iron present in the soil.
Reason (R): The dark particles sticking to the magnet are bits of iron present in the soil.
Answer: (a)
Both A and R are true, and R is the correct explanation of A. Soil often contains small iron particles, which are magnetic and cling to the magnet when it is dragged through the dirt.
20
Assertion (A): Magnets are commonly used in everyday items like refrigerator doors and pin holders.
Reason (R): Magnets help to keep the doors tightly closed and pins securely attached due to magnetic attraction.
Reason (R): Magnets help to keep the doors tightly closed and pins securely attached due to magnetic attraction.
Answer: (a)
