What shall we call it? Michael Faraday got the term diamagnetism from William Whewell.

A ferromagnetic material can be permanently magnetized; it can have its own persistent magnetic field. Diamagnetic and paramagnetic materials get only temporary magnetic fields induced by other magnetic fields. The induced magnetic field in a diamagnetic material is in the opposite direction, so an exterior magnetic field repels it. The induced magnetic field in a paramagnetic material is in the same direction, so an exterior magnetic field attracts it.
