Description
A general name for highly magnetic films made from rare earth elements. The strength of rare earth magnets exceeds those of ferrite magnets by approximately 10-fold. Additionally, they are lightweight, as thin as 0.06 inches, and are resistant to corrosion and demagnetization. Rare earth magnets are divided into two categories, that is, the SmCo-type (samarium-cobalt) rare earth magnets and the NdFeB-type (neodymium-iron-boron) magnets (also called Nd magnets). More than 98% of the rare earth magnets are the Nd magnets
