Larger neodymium magnets are used in high-power-versus-weight electric motors (for example in hybrid cars) and generators (for example aircraft and wind turbine electric generators).Neodymium, a rare-earth metal, was present in the classical mischmetal at a concentration of about 18%.The name neodymium is derived from the Greek words neos (νέος), new, and didymos (διδύμος), twin.

The reserves of neodymium are estimated at about eight million tonnes.Neodymium is never found in nature as a free element, but rather it occurs in ores such as monazite and bastnäsite (these are mineral group names rather than single mineral names) that contain small amounts of all the rare-earth metals.In these minerals Nd is rarely dominant (as in the case of, e.g., La), with Ce being the most abundant lanthanide; some exceptions include monazite-(Nd) and kozoite-(Nd).Most of the world's commercial neodymium is mined in China.Neodymium compounds were first commercially used as glass dyes in 1927, and they remain a popular additive in glasses.

These have been used in extremely-high-power applications, such as experiments in inertial confinement fusion.
