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 ...
Jan 16, 2023 · The most powerful rare earth alloy magnets are neodymium-iron-boron magnets. A three-kilogram neodymium alloy magnet can lift objects that weigh over 300 kilograms, for instance.
The problem seemed unsolvable since an intermetallic compound is a basic requirement of any rare-earth magnet. Although the intermetallic phase Nd 2 Fe 17 did form, its properties were unsuitable ...
Jan 5, 2024 · China has dominated the market for rare earth elements, but US scientists and companies are scrambling to catch up. By. Mureji Fatunde. January 5, 2024. US-based Noveon Magnetics extracts ...
Jul 6, 2022 · The Strength of Rare Earth Magnets. Each magnet has a grade, which typically denotes its strength. For example, a neodymium magnet of grade N42 has a strength of 42MGOe. To put the power of two common rare earth magnet grades into perspective, here’s how their strength compares with common grades of other permanent magnets: Magnet (Grade ...
