A samarium cobalt magnet (sintered smco magnet)is a strong permanent magnet made of an alloy of samarium and cobalt.Samarium cobalt magnets have maximum energy products (BHmax) that range from 16 megagauss-oersteds (MGOe) to 32 MGOe, that is approx. 128 kJ/m3 to 256 kJ/m3; their theoretical limit is 34 MGOe, about 272 kJ/m3. They are available in two
