- This means a magnetic material with a large coercive force and which is not easily demagnetized by external magnetic fields. This generally means a magnet or permanent magnet but magnetic recording materials can be called a type of hard magnetic material. Ferrite magnets, NdFeB family magnets, SmCo family magnets, and other rare earth magnets, platinum iron, platinum cobalt, FeCoCr alloys are among the representative magnetic material.
