Rare earth permanent magnets
Rare-earth magnets are strong permanent magnets made from alloys of rare-earth elements. 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). Today, 16.000 tons of rare-earth PMs are consumed each year in renewable energy, machine tools, robotics, loudspeakers, water pumps, mobility and ICT.
