There are typically four categories of permanent magnets: neodymium iron boron (NdFeB), samarium cobalt (SmCo), alnico, and ceramic or ferrite magnets. This type of magnet is composed of rare earth magnetic material, and has a high coercive force. ... They are very strong magnets and are difficult to demagnetize.
