How can magnets lose their magnetism
WebPermanent magnets emit a magnetic field without any external source of electric power or magnetism. They do not easily lose their magnetism. Temporary magnets rely on outside forces and become magnetized when they are around a stronger magnet. They will lose their magnetism gradually when the other magnet and magnetic field is removed. WebThe rare-earth elements are metals that are ferromagnetic, meaning that like iron they can be magnetized to become permanent magnets, but their Curie temperatures (the temperature above which their ferromagnetism …
