Question

How can a magnet be demagnetized?

Answer 1

The process by which a magnet loses its magnetic properties is called demagnetization. Some of the methods to demagnetize a magnet are as follows:

1. By improper or rough handling.
2. By placing the magnet in the east-west direction and rapidly heating followed by rapid cooling.
3. By passing an electric current of high frequency.
4. Sometimes magnets under self-induction also lose magnetism.

Thus, we can conclude that the demagnetization of magnets is majorly due to the mishandling of magnets.
