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.
A rare earth magnet is a magnet made from one of the rare earth elements (of which there are 17) in the Lanthanide series of metals in the periodic table. The two most common rare earth magnets are Neodymium (Nd-Fe-B) and Samarium Cobalt (SmCo). Read more about these two types of magnets.
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.
Jan 5, 2024 · January 5, 2024. US-based Noveon Magnetics extracts materials from discarded commercial magnets like this one to make new magnets for wind turbines and electric vehicles. Courtesy of Noveon...
Jul 6, 2022 · Neodymium and samarium—two of the 17 rare earth elements—are ferromagnetic, meaning that they have inherent magnetic properties and can be magnetized. These metals are first mined, refined, and then combined with materials like iron, boron, and/or cobalt to make the strongest magnetic alloys.
To develop an economically viable permanent magnet, Croat knew he needed to produce it from a light rare-earth element, such as lanthanum, cerium, praseodymium or neodymium, which together...
What are Rare Earth Magnets? Rare-earth magnets are permanent magnets having a composition of alloys manufactured from rare earth elements (mostly elements from lanthanide series, and alloys). They were developed in the 1970s and 1980s and are the strongest types of permanent magnets.

Dec 29, 2023 · One of the most important and wide range of applications for rare earth (REs) containing materials is the production of permanent magnets.
Feb 1, 2020 · Rare earth permanent magnets constitute a mature technology, but the shock of the 2011 rare earth crisis led to the re-evaluation of many ideas from the 1980s and 1990s about possible new hard magnets containing little or no rare earth (or heavy rare earth).
Apr 16, 2024 · Rare earth magnets refer to powerful permanent magnets composed of rare earth element alloys. Among permanent magnets, rare earth magnets can generate the largest magnetic field, which is much larger than that of AlNiCo magnets or ferrite magnets.
