Temporary and permanent magnets
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.

Web5 Oct 2024 · Iron as a temporary magnet: Iron can be easily magnetised or demagnetised (soft magnetic material. It can even be magnetized by a weak magnetic field. it is therefore suitable to be used in temporary magnets. When mixed with other metals (e.g. Ni, Cu, Mn, Si), powerful temporary magnets can be made.
WebSolution: Temporary magnet: It is made up of soft iron. As soon as the magnetising force is removed the magnet loses its magnetism. It is not used to make an iron piece into a magnet, because of its weak power.
