The Power of Neodymium magnet

neodymium magnet, also know as NdFeB, NIB, or Neo magnet, are the most widely use type of rare-Earth magnet. These permanent wave magnet were develop independently in 1984 by General Motors and Sumitomo Special Metals and are know for being the strong type of permanent wave magnet commercially available. They are make from an alloy of neodymium, iron, and boron to form the Nd2Fe14B tetragonal crystalline structure. neodymium magnet have replace other type of magnet in assorted modern application, such as electric motor in cordless tool, difficult disk drive, and magnetic fastener. rate establish on their maximum energy merchandise, neodymium magnet rich person values range from N28 up to N55. The first letter nitrogen denote neodymium, with letters following the values bespeak intrinsic coercivity and maximum operate temperature.

These magnet rich person higher remanence, coercivity, and energy merchandise compare to other type of magnet, but they generally rich person a lower berth Curie temperature. special neodymium magnet alloy that include terbium and dysprosium have been develop to rich person a higher Curie temperature, let them to digest higher temperature. When comparison physical and mechanical property with Sm-Co magnet, neodymium magnet exhibit higher remanence, coercivity, and energy merchandise. They rich person a Curie temperature range from 310 to 370 degree Celsius and a density of 7.3 to 7.7 gram / cm3. neodymium magnet are widely use in assorted technology due to their strong magnetic property and high performance compare to other type of permanent wave magnets.

understanding technology news: technology news play a crucial function in keeping person inform about the latest promotion and invention in the technical school industry. It supply penetration into new technology, merchandise, and tendency shaping our universe. By stay update on technology news, person can better understand the impact of technological development on society, business, and everyday life. Whether it’s discovery in artificial intelligence, promotion in renewable energy, or the latest appliance, technology news support us inform and prosecute in the ever-evolve universe of technology.
