WebHowever, it was not until the 18th century that the first man-made magnets were created. Progress in creating stronger magnetic alloys was very slow until the 1920s when alnico magnet materials (an alloy of nickel, aluminum and cobalt) were formulated. Ferrite magnets were developed in the 1950s and rare-earth magnets in the 1970s. WebNote however, that ferrite magnets lose 25% of their flux output when heated from 20 to 150 °C. They also have relatively low energy products, typically 10% of rare earth magnets. So where device size and weight are important, such as hard disk drives and portable electronics (e.g. cell phones, hearing aids), rare earth magnets are necessary.
WebThe rare earth magnets have a field strength of more than 1.4 Tesla, whereas ceramic and ferrite magnets have fields of 0.5 to 1.0 Tesla. There are two types of rare earth magnets, and they are neodymium magnets and samarium–cobalt magnets.
