Rare Earth Magnets

Rare earth magnets are strong permanent magnets made from compounds of rare earth elements. Developed in the 1970s and 80s, 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. There are two types: neodymium magnets and samarium-cobalt magnets. Rare earth magnets are extremely fragile and also vulnerable to corrosion, hence are usually plated or coated to protect them from breaking.

 

The term “rare earth” can be misleading as these metals are not particularly rare or precious—they are about as abundant as tin or lead. The unparalleled strength of neodymium magnets is only possible due to a sophisticated and delicate arrangement of atomic particles and their electron spin. The process to produce these technological marvels is no less sophisticated or delicate.
