                               Short Answer Questions on Magnetism

Que-1: What is a magnet?

Ans- A magnet is an object that produces a magnetic field and can attract certain metals like iron. It has two poles, north and south, which can attract or repel other magnets.

Que-2: What are magnetic and non-magnetic substances? Give two examples of each.

Ans- Magnetic substances are materials that are attracted to a magnet. Examples include iron and nickel.
Non-magnetic substances are materials that are not attracted to a magnet. Examples include wood and plastic.

Que-3: What are natural and artificial magnets?

Ans- Natural magnets are magnets that occur in nature without being made by humans. An example is lodestone, a naturally magnetized form of the mineral magnetite.
Artificial magnets are magnets that are made by people. They can be shaped and designed for different uses, such as bar magnets, horseshoe magnets, and electromagnets.

Que-4: How is an artificial magnet prepared from a natural magnet?

Ans- An artificial magnet is prepared from a natural magnet by a process called stroking. In this method, a piece of iron or steel is rubbed in one direction several times with one pole of a natural magnet . After repeated stroking in the same direction, the iron or steel becomes magnetized and acts as an artificial magnet.

Que-5: State two ways of magnetising an iron piece.

Ans- Two ways of magnetising an iron piece are:
(a)Stroking method – Rubbing the iron piece several times in one direction with a magnet.
(b)Electrical method – Passing electric current through a coil of wire wound around the iron piece (making an electromagnet).

Que-6: How can magnetic properties of a magnet be destroyed?

Ans- The magnetic properties of a magnet can be destroyed by heating it strongly, hammering or dropping it repeatedly, or by placing it in a strong magnetic field in the opposite direction. These actions disturb the alignment of the tiny magnetic particles inside the magnet, causing it to lose its magnetism.

Que-7: Why does a freely suspended magnet always rest in north-south direction?

Ans- A freely suspended magnet always rests in the north–south direction because of the Earth’s magnetic field.
The Earth behaves like a giant magnet, so when a magnet is allowed to move freely, its north pole is attracted toward the Earth’s magnetic south (near the geographic north), and its south pole is attracted toward the Earth’s magnetic north. This makes the magnet align itself in the north–south direction.

Que-8: Why are artificial magnets preferred over the natural magnets?

Ans-  Artificial magnets are preferred over natural magnets because they can be made in any desired shape and size, are stronger, and their magnetic strength can be controlled. Natural magnets, like lodestone, are rare, irregular in shape, and usually weaker, making them less practical for most applications.

Que-9: State four important properties of a bar magnet.

Ans- Four important properties of a bar magnet are:
(i)It has two poles — a north pole and a south pole.
(ii)Like poles repel each other and unlike poles attract each other.
(iii)Magnetic force is strongest at the poles.
(iv)A freely suspended bar magnet always rests in the north–south direction.

Que-10: How are the magnets kept safely ? What is the role of keepers in storing magnets?

Ans- Magnets are kept safely by storing them with keepers, which are pieces of soft iron placed across their poles.
The role of keepers is to maintain the magnet’s strength by providing a closed path for the magnetic lines of force. This prevents the magnet from losing its magnetism over time due to exposure to air, shocks, or stray magnetic fields. Without keepers, magnets can gradually become weaker.

Que-11: State two ways of increasing the strength of an electromagnet.

Ans- Two ways to increase the strength of an electromagnet are:
(i)Increasing the number of turns of the coil around the iron core.
(ii)Increasing the electric current flowing through the coil.

Que-12: State three important uses of a magnet.

Ans- Three important uses of a magnet are:
(i) In compasses to find directions.
(ii)In electric motors and generators to convert electrical energy to mechanical energy and vice versa.
(iii)In magnetic cranes to lift heavy iron and steel objects.

Que-13: In which direction does a suspended bar magnet come to rest ? Give reason.

Ans-  A suspended bar magnet comes to rest in the north–south direction.
Reason: The Earth acts like a giant magnet, so the north pole of the bar magnet is attracted toward the Earth’s magnetic south (near the geographic north), and the south pole is attracted toward the Earth’s magnetic north. This alignment makes the magnet settle along the north–south line.

Que-14: State three differences between temporary and permanent magnets.

Ans-

Temporary Magnet	Permanent Magnet
(i)	It is made of soft iron.	It is made of steel.
(ii)	It is easily demagnetised.	It is not easily demagnetised.
(iii)	Its magnetic strength can be changed.	Its magnetic strength cannot be changed.

Que-15: State three ways of demagnetising a magnet.

Ans- Three ways of demagnetising a magnet are:
(i)Heating – Strongly heating a magnet can disturb the alignment of its magnetic particles, causing it to lose magnetism.
(ii)Hammering or striking – Repeatedly hitting or dropping a magnet can weaken or destroy its magnetic properties.
(iii)Using an opposite magnetic field – Placing a magnet in a strong magnetic field opposite to its own can cancel its magnetism.

Que-16: Suggest one way to recognise the magnetic field of the earth.

Ans- One way to recognize the magnetic field of the Earth is by using a freely suspended bar magnet. When suspended, the magnet aligns itself along the north–south direction, showing the presence and direction of the Earth’s magnetic field.

Que-17: Name the material of core of an electromagnet for
(a) temporary magnet
(b) permanent magnet.

Ans- The core materials for an electromagnet are:
(a) Temporary magnet – Soft iron (because it can be easily magnetised and demagnetised)
(b) Permanent magnet – Steel (because it retains magnetism for a long time)

Que18: What are magnetic keepers ? Name its material.

Ans-  Magnetic keepers are pieces of soft iron placed across the poles of a magnet when it is stored. They help preserve the magnet’s strength by providing a closed path for magnetic lines of force.
Material: Soft iron.

Que-19: How are the north and south poles of a magnet located? Explain.

Ans-  To locate the north and south poles of a magnet, suspend it freely with a thread. It will come to rest in the north-south direction. The end that points towards the geographic north is the magnet’s north pole, and the end pointing south is its south pole. This happens because Earth’s magnetic field attracts the opposite poles of the magnet.
