WebFerrite magnets have ferrimagnetic properties. Compared to Alnico, it has much higher Intrinsic coercivity making it much better at resisting demagnetisation from external magnetic fields and from other magnets). This allowed it to be used much more successfully in electric motors and generators where it is still an extremely popular magnet. WebThese permanent magnets are made from two rare-earth elements – samarium and cobalt. It is important to note that when producing SmCo magnets, the cobalt portion can be replaced by transition metals, while the samarium portion can be replaced by cerium and gadolinium.
