These are used to make neodymium magnets. The strength of neodymium magnets is the result of several factors. The most important is that the tetragonal Nd 2 Fe 14 B crystal structure has exceptionally high uniaxial magnetocrystalline anisotropy (H A ≈ 7 T – magnetic field strength H in units of A/m versus magnetic moment in A·m 2).
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 ...
Neodymium is the fourth member of the lanthanide series. In the periodic table, it appears between the lanthanides praseodymium to its left and the radioactive element promethium to its right, and above the actinide uranium. Its 60 electrons are arranged in the configuration [Xe]4f 4 6s 2, of which the six 4f and 6s electrons are valence.
Fields. Metallurgy, Magnetic Materials, Sustainable energy. 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.
Globally, most REEs are used for catalysts and magnets. [127] In the US, more than half of REEs are used for catalysts; ceramics, glass, and polishing are also main uses. [128] Other important uses of rare-earth elements are applicable to the production of high-performance magnets, alloys, glasses, and electronics.
Superconducting magnet. Schematic of a 20-tesla superconducting magnet with vertical bore. A superconducting magnet is an electromagnet made from coils of superconducting wire. They must be cooled to cryogenic temperatures during operation. In its superconducting state the wire has no electrical resistance and therefore can conduct much larger ...
