Question

what is demagnetisasion? give three ways to demagnetise a magnet​.

Answer 1

Answer:

Demagnetization processes include heating past the Curie point, applying a strong magnetic field, applying alternating current, or hammering the metal

Explanation:

Answer 2

Demagnetization processes include heating past the Curie point, applying a strong magnetic field, applying alternating current, or hammering the metal.

Three ways to demagnetize magnet are:

1) Heating the magnet to temperature > curie temperature

2) Heavy shocks can even distort the elementary magnets to demagnetize.

3)With a strong enough magnetic field of opposite polarity, it is therefore possible to demagnetize the magnet.
