Temporary Magnet
a magnet with a force field that attracts other objects for a short period of time
A temporary magnet is a type of magnet that only exhibits magnetic properties when in the presence of a magnetic field. It does not retain its magnetism when the external field is removed.
There are various ways that temporary magnets can be created. One of the most common methods is by placing a piece of magnetic material such as iron or steel in a strong magnetic field. The magnetic field causes the electrons in the material to align in a certain direction, creating a temporary magnetic field in the material.
Another way to create a temporary magnet is by electromagnetic induction. This involves passing an electric current through a coil of wire, which then generates a magnetic field. The coil can then be used to magnetize a piece of iron or steel.
Temporary magnets are used in a range of applications, including in electric motors and generators, speakers, and magnetic locks. They are also widely used in household appliances such as refrigerators and washing machines, where they help to hold doors closed or keep parts in place.
Overall, temporary magnets are an important tool in the world of magnetism and are used in a variety of everyday applications.
