Why does a magnet loses its magnetism when it is strongly heated or hammered?

Answer 1

A magnet is an alignment of particles in a solid. You can imagine a magnet as a bunch of tiny magnets that are all pointing in the same direction. When they point in the same direction, the little parts add up, and the magnet works like you'd expect.

When you heat or hammer a magnet, the little magnetic parts can get jostled and unaligned. When that alignment is disturbed, they no longer point in the same direction and may even cancel other magnetic parts out, weakening and eventualy destroying the magnetism.

Answer 2

The answer is: Yes, it does.

And the reason is this: In a magnet the electrons in the atoms are spinning in the same direction, which gives a magnet its magnetic domain-north or south-and creates a magnetic field.

If the electrons are spinning every which way, the domains are scattered and the magnet is not magnetized.

Dropping, hitting, or heating a magnet will disturb the magnetic field-the spin of the electrons goes out of alignment and becomes random. (If you heat the magnet, the electrons start moving more quickly and can vibrate out of alignment with the domain.) The answer is: Yes, it does.

Answer 3

It can.

Magnets do what they do because the positive and negative building blocks of the magnet are lined up uniformly. Dropping the magnet causes the components to vibrate and they may realign out of order, thus weakening the unity of the magnetic force.

You can also create a magnet using a simple piece of soft iron. If you align it with the magnetic poles of a magnetic force, even that of the earth itself, and strike it with a hammer, causing the components to vibrate, some will align with the magnetic direction of the magnetic field, or the magnetic north pole of the earth, creating a magnetic unity.

Answer 5

Heat or shock. Heating it past a certain point, or subjecting it to a hard mechanical shock will rearrange the magnetic domains so that they are no longer alligned. Also, an alternating magnetic field will neutralize a weaker magnet. The process is called "Degaussing".
If you burn it.

Answer 6

the magnetism in it losses so it will not work any more and become more weaker
