Rare-earth magnets and ceramic magnets tend to be types of permanent magnet; both are composed of materials which, once given a magnetic charge, will retain their magnetism for some time unless they become damaged. Not all permanent magnets are the same, however. Rare-earth and ceramic magnets differ into their strength and resilience since they are made out of different metal alloys.

Ceramic magnets have been used considering that the 1960s. Ceramic magnets were less pricey and even more powerful than the aluminum-nickel-cobalt and steel magnets that had previously been in use, and quickly became popular. SmCo magnets were developed within the 1970s and were the initial of the rare-earth magnets to be produced. NdFeB magnets became available to stock up 1984.
