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...
