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 ...
Samarium–cobalt magnet. A samarium–cobalt (SmCo) magnet, a type of rare-earth magnet, is a strong permanent magnet made of two basic elements: samarium and cobalt. They were developed in the early 1960s based on work done by Karl Strnat at Wright-Patterson Air Force Base and Alden Ray at the University of Dayton.
Inventor Masato Sagawa demonstrating a NdFeB magnet's force with 2 kg bottle. 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.
MP Materials focuses its production on Neodymium-Praseodymium (NdPr), a rare earth material used in high-strength permanent magnets that power the traction motors found in electric vehicles, robotics, wind turbines, drones and other advanced motion technologies. [12] MP Materials is listed on the New York Stock Exchange under the ticker symbol ...
Praseodymium. double hexagonal close-packed (dhcp) (hP4) Praseodymium is a chemical element; it has symbol Pr and the atomic number 59. It is the third member of the lanthanide series and is considered one of the rare-earth metals. It is a soft, silvery, malleable and ductile metal, valued for its magnetic, electrical, chemical, and optical ...
A U.K. tech company called Materials Nexus recently announced, with the help of its AI platform, they’d developed a magnet that’s completely free of rare earth metals. While this isn’t the ...
