How Neodymium Magnets are Made

Note that the powder formed by this reaction is slightly different than the Nd 2 Fe 14 B 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 Nd 2 Fe 14 B grains.. For higher temperature magnet grades, additional elements are added.
