What are Rare Earth Magnets?
They are strong permanent magnets made from alloys of Rare Earth elements. Developed in the 1970s and 1980s, These are the strongest type of permanent magnets made. They also produce significantly stronger magnetic fields than other types such as ferrite or alnico magnets. The magnetic field produced by Rare Earth magnets can exceed 1.4 teslas, whereas ferrite or ceramic magnets typically exhibit fields of 0.5 to 1 tesla.
