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.
