Question

explain using the domain theory why heating or dropping a magnet can cause it to lose its magnetization explain using the domain theory why heating or dropping a magnet can cause it to lose its magnetization @Physics

Answer 1

Permanent magnetism is due to the alignment of the magnetic domains inside the material. If the material is heated, the individual atoms are given more kinetic energy, and there comes a point (called the Curie point) where the organized domain structure breaks down and the magnetism is lost. Likewise, if you were to drop a magnet, the vibrations induced by the impact would destroy the domain alignment.
