Magnetism of a magnet is lost by doing which of the following acts
- a)Keeping in a box
- b)Heating
- c)Hammering
- d)Both b and c
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
Magnetism of a magnet is lost by doing which of the following actsa)Ke...
The correct option is D.
Most permanent magnets can hold up to being dropped a few times, but it will lose strength from repeated strikes with a hammer.A magnet subjected to heat experiences a reduction in its magnetic field as the particles within the magnet are moving at an increasingly faster and more sporadic rate. This jumbling confuses and misaligns the magnetic domains, causing the magnetism to decrease.

Explanation:
Magnetism of a magnet is lost by doing which of the following acts?
Magnetism is a property of certain materials that can attract or repel other materials. A magnet has two poles, a north pole and a south pole, and it creates a magnetic field around it. The strength of the magnetic field determines the magnet's magnetic force.
There are several ways in which a magnet can lose its magnetism. Let's explore each of the given options to understand why heating and hammering can cause a magnet to lose its magnetism.
a) Keeping in a box:
Keeping a magnet in a box does not cause it to lose its magnetism. The presence of a box does not affect the magnetic field or the alignment of the magnetic domains within the magnet. Therefore, this option does not cause the loss of magnetism.
b) Heating:
Heating a magnet can cause it to lose its magnetism. When a magnet is heated, the thermal energy disrupts the alignment of the magnetic domains within the magnet. The magnetic domains become disordered, and the magnetism is lost. This is because heating provides enough energy to overcome the magnetic forces that hold the domains in alignment. As a result, the magnet becomes demagnetized.
c) Hammering:
Hammering a magnet can also cause it to lose its magnetism. When a magnet is hammered, the mechanical energy from the impact can disrupt the alignment of the magnetic domains. The force exerted by the hammer can cause the magnetic domains to move out of alignment or become misaligned. As a result, the magnetism is lost, and the magnet becomes demagnetized.
d) Both b and c:
Both heating and hammering can cause a magnet to lose its magnetism. Heating disrupts the alignment of the magnetic domains by providing thermal energy, while hammering disrupts the alignment through mechanical energy. The combined effect of heating and hammering can further weaken the magnetic field and lead to a complete loss of magnetism.
Therefore, option d) "Both b and c" is the correct answer as both heating and hammering can cause the magnetism of a magnet to be lost.
