Temporary magnetism
WebA temporary magnet acts as a magnet only as long as it is in the magnetic field of a permanent magnet. A lodestone is a natural permanent magnet. You investigate permanent magnets that have been made artificially. … WebTemporary magnet: Temporary magnets are made of soft metals that are magnetised only when exposed to a permanent magnetic field or an electric current. When they come into contact with a magnetic field, they become magnetized. When the magnetic field is removed, they gradually lose their magnetism.
