Answer:
There are three types of magnets
1. electromagnet
2. permanent magnet
3.temporary magnet
Explanation:
Temporary magnets become magnetized in the presence of a magnetic field. They lose their magnetism gradually, when the magnetic field is removed. Some irons and iron alloys, as well as paper clips and nails, function as temporary magnets.
Permanent magnets do not easily lose their magnetism. These magnets may be naturally-occurring (“rare-earth”) elements, or chemical compounds
Electromagnets are created by running an electrical current through a coil with a metal core. The energized coil creates a magnetic field. When the current is shut off, the magnetic field disappears
