FAQ:How do you demagnetize a magnet

When the field is reduced and reversed not all these magnetic poles will reverse. Hence, by repeating this process many time (that''s why an AC current is needed) and also by reducing the magnitude of the current as we go, to reduce the strength of the (electro-)magnetic field, the magnetism of the magnet can be reduced to almost zero or perhaps for most practical purpose zero.
