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. [2] Developed independently in 1984 by General Motors and in 1970s by Sumitomo Special Metals ...
Neodymium magnets appear in products such as microphones, professional loudspeakers, headphones, guitar and bass guitar pick-ups, and computer hard disks where low mass, small volume, or strong magnetic fields are required. Neodymium is used in the electric motors of hybrid and electric automobiles and in the electricity generators of some ...
Scientists. v. t. e. In electromagnetism, permeability is the measure of magnetization produced in a material in response to an applied magnetic field. Permeability is typically represented by the (italicized) Greek letter μ. It is the ratio of the magnetic induction to the magnetizing field as a function of the field in a material.
Under the partnership with VAC, GM and the German company will build a plant in the U.S. that will manufacture permanent magnets for the electric motors. The agreement with VAC is non-binding at ...
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 ...
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.
NFPA 704 safety squares on containers of ethyl alcohol and acetone. " NFPA 704: Standard System for the Identification of the Hazards of Materials for Emergency Response " is a standard maintained by the U.S. -based National Fire Protection Association. First "tentatively adopted as a guide" in 1960, [1] and revised several times since then, it ...
Updated Fri, Oct 23, 2015 · 1 min read. Introduced to the public way back in 2004, Dyson's first robot vacuum never wheeled itself into retail. While it was apparently close enough to a finished ...
