How many types of magnet are there?
There are several different types of magnets. Permanent magnets are made of ferromagnetic materials and are the most commonly used type of magnet, including for refrigerator magnets. Temporary magnets are similar to permanent magnets, except that they must be used within a strong magnetic field. Electromagnets are very strong magnets that are used with a core, and are popular when used inside TVs, computers, and other types of electronics. Superconductors are another type of magnets. These are the strongest magnets available.
