How were neodymium magnets invented?

Note that the powder formed by this reaction is slightly different than the Nd2Fe14B ratio. Magnets are often made both Nd-rich and B-rich, where finished magnets typically contain non-magnetic bits of Nd and B in the grain, within which are highly magnetic Nd2Fe14B grains. read more

A neodymium magnet (also known as NdFeB, NIB or Neo magnet), the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron to form the Nd 2 Fe 14 B tetragonal crystalline structure. read more

Magnets are often made both Nd-rich and B-rich, where finished magnets typically contain non-magnetic bits of Nd and B in the grain, within which are highly magnetic Nd 2 Fe 14 B grains. For higher temperature magnet grades, additional elements are added. read more
