What is a rare earth magnet?

Best Answers

Rare-earth magnets are strong permanent magnets made from alloys of rare-earth elements (elements in the lanthanide series, plus scandium and yttrium). The magnetic field typically produced by rare-earth magnets can exceed 1.4 teslas, whereas ferrite or ceramic magnets typically exhibit fields of 0.5 to 1 tesla. read more

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. read more

Rare earth magnets punch in at around 1.4 Teslas and can generate even higher magnetic fields. The term “rare earth” is also a bit of a misnomer. Rare earth elements, coming from the lanthanide, scandium, and yttrium families of the periodic table, are actually fairly abundant. read more

Rare earths are a series of chemical elements found in the Earth’s crust that are vital to many modern technologies, including consumer electronics, computers and networks, communications, clean energy, advanced transportation, health care, environmental mitigation, national defense, and many others. read more
