Neodymium - Wikipedia ... Neodymium
A rare-earth magnet is a strong permanent magnet made from alloys of rare-earth elements. Developed in the 1970s and 1980s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets. The magnetic field typically produced by rare-earth ...

Masato Sagawa (佐川眞人; born August 3, 1943, in Tokushima, Japan) is a Japanese scientist and entrepreneur, and the inventor of the sintered permanent neodymium magnet (NdFeB). Sagawa was awarded the Japan Prize and IEEE Medal for Environmental and Safety Technologies for his efforts.
Magnetic alloys have become common, especially in the form of steel (iron and carbon), alnico (iron, nickel, cobalt, and aluminum), and permalloy (iron and nickel). So-called " neodymium magnets " are alloys of neodymium, iron and boron forming the crystal structure Nd 2 Fe 14 B.
