Types of Magnets
The three types of magnets are temporary, permanent, and electromagnets.
Magnets are categorized by their source of magnetism.
Screwdrivers can be temporarily magnetized
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.
Permanent magnet examples include Alnico (an alloy of aluminum, nickel, and cobalt) and ferrites (ceramic-like material made from a mix of iron oxides with nickel, strontium, or cobalt).
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.
Electromagnets are preferred for applications that require strength including rail road tracks, motor engines, MRI machines, and cranes. They’re also used in computer and television hardware.
