A neodymium magnet (also known as NdFeB, NIB or Neo 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. [1] They are the most widely used type of rare-earth magnet .
This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. ... Neodymium: 7.007: 41.5 ...
The magnets used for implantation must be carefully selected and coated in order to successfully implant them. Size is important in this consideration, as too large of a magnet obstructs blood vessels and is likely to reject, or push out of the skin. For this reason, the most common magnet size is a 3×1mm neodymium disk magnet. Usually the ...
Neodymium also has 15 known metastable isotopes, with the most stable one being 139m Nd (t 1/2 = 5.5 hours), 135m Nd (t 1/2 = 5.5 minutes) and 133m1 Nd (t 1/2 ~70 seconds). The primary decay modes before the most abundant stable isotope, 142 Nd, are electron capture and positron decay , and the primary mode after is beta minus decay .

[1] [2] During this same time period, John Croat from General Motors (GM) had independently discovered the same Nd 2 Fe 14 B compound. [3] In 1988, Sagawa founded Intermetallics, a research and development company devoted to the development of neodymium magnets. [4] [5] [6] Sagawa founded NDFEB Corporation in 2012, where he is currently president.
