2. Ferrite (magnet) - Wikipedia

   en.wikipedia.org/wiki/Ferrite_(magnet)

   These so-called ceramic magnets are cheap, and are widely used in household products such as refrigerator magnets. The maximum magnetic field B is about 0.35 tesla and the magnetic field strength H is about 30–160 kiloampere turns per meter (400–2000 oersteds). [33] The density of ferrite magnets is about 5 g/cm 3.

   The neodymium atom can have a large magnetic dipole moment because it has 4 unpaired electrons in its electron structure [14] as opposed to (on average) 3 in iron. In a magnet it is the unpaired electrons, aligned so that their spin is in the same direction, which generate the magnetic field.
