Cerium magnet is made by combining cerium with other metal elements to create an alloy that can be magnetized. Cerium magnets have several advantages over other types of magnets. Cerium is four times more abundant and significantly less expensive than neodymium, which is frequently used in today’s most powerful magnets. Cerium-based intermetallics are currently attracting much interest as a possible alternative to existing high-performance magnets containing scarce heavy rare-earth elements. The high temperature capabilities of cerium magnets would let motors made from them run at correspondingly higher temperatures. That means that the currents pushed through their coils can be higher, longer, and stronger.
