Where are temporary magnets used?
It makes sense that since some magnets are called "permanent magnets," other magnets should be called "temporary magnets." But since when did English make sense? We usually call them "electromagnets" instead. Electromagnets are used in most electric motors, and cranes that lift scrap metal. They're also used in relays and the write heads of tape recorders (including video tape recorders).

How are temporary magnets different from permanent magnets?
They are temporary, they can only attract for a few seconds, as permanent magnets can attract for as long it is needed.AnswerA permanent magnet is a material which retains its magnetism once any external magnetising force has been removed. For example, when the current passing though a coil wound around that material is switched off. Permanent magnets are used in certain measuring instruments, such as moving-coil instruments, fridge magnets, etc.A temporary magnet is a material which retains its magnetism providing any external magnetising force continues to be applied. For example, when the current passing though a coil wound around that material flows, it will continue to act as a magnet, but once the current is turned off it will lose that magnetism (or most of it!). Temporary magnets are used to manufacture relays, transformer cores, etc.
