What is the difference between a permanent magnet and a temporary magnet
Pernament magnet is one that retains its magnetic properties for a long period of time. Temporary megnet only maintains its magnetism while in a magnetic field produced by permanent magnet or electric current.
A permanent magnet does not loose its magnetism easily. It can only be lost by permanent destruction say by fire. Example of this is magnetism from a bar magnet. This magnetism is not induced by say electric current. A temporary magnet looses its magnetism easily. The magnetism is gained or loosed for the action of carrying out a particular task. This magnetism can be achieved by the gain or loss by passing of electric current over say an iron core.
