Question

Which different actions can destroy magnetism?​

Answer 1

Answer:

Hitting a magnet with enough force to destroy its north and south pole alignment will force the magnet out of alignment. Any violent trauma can cause this to happen including drilling and hitting with a tool. If the grains inside the magnet no longer line up properly, the magnet will no longer function properly.

Answer 2

Answer:

Magnetism can be destroyed by heating or hammering the magnetic material, but cannot be destroyed or isolated by simply breaking the magnet into two pieces.
