Question

How can the magnetic properties of a magnet be destroyed?

Answer 1

Demagnetization:

The process of destroying the magnetic properties of a magnet is called demagnetization.

Demagnetization can be done in the following ways:

1. By rough handling.
2. By dropping the magnet on the floor or on a hard surface in a number of times.
3. By hammering the magnet repeatedly.
4. By heating the magnet to a very high temperature.
5. Bypassing alternating current around the magnet.
