    Rare,  · Rare-earth magnets are strong permanent magnets 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 ...DIY,  · 🔥🔥🔥DIY - How To Make Industrial Revolutionary Steamboat With Magnetic Balls (ASMR) 🚢🚗Amazing Vehicle: How To Make Gulfstream G450 Aircraft https://.yout...DIY,  · To Make BOWLING With Magnetic Balls (ASMR) 🚢🚗Amazing Vehicle: How To Make Gulfstream ...

By the early 1980s, further research into the magnetic properties of rare earth elements led to the discovery of neodymium-iron-boron (NdFeB) magnets, which led to a doubling of the magnetic energy over SmCo magnets..

    NdFeB permanent magnet materials to create new technological processes recipes_Company News_WONDEW MAGNET,  · "industrial MSG," said rare earth on the future development of new energy vehicles play a key role. NdFeB permanent magnet, a permanent magnet NdFeB magnet magnetic highest found so far, has a very high energy product and coercive force ...Neodymium Sphere Magnets Magnetic Ball,  · These Magnet Balls are protected by a shining chrome-colored Ni-Cu-Ni coating, so to protect your powerful magnet spheres from rusting. Sphere Magnet- a magnet that creates a strong magnetic field which attracts iron & other ferrous materials in the shape of a sphere.Additive manufacturing of Sm,  · Isotropic Sm-Fe-N bonded magnets were obtained by additive manufacturing (AM). The technique used was the so-called powder bed fusion (PBF) and the feedstock was composed of a polymeric binder (PA-12) and Sm-Fe-N flake particles (Nitroquench-P). The AM ...Neodymium magnet,  · This magnetic energy property is higher in NdFeB alloys than in samarium cobalt (SmCo) magnets, which were the first type of rare-earth magnet to be commercialized. In practice, the magnetic properties of neodymium magnets depend on the alloy composition, microstructure, and manufacturing technique employed.Electropermanent magnet,  · An electropermanent magnet or EPM is a type of permanent magnet in which the external magnetic field can be switched on or off by a pulse of electric current in a wire winding around part of the magnet. The magnet consists of two sections, one of "hard" (high coercivity) magnetic material and one of "soft" (low coercivity) material..
