Scientists develop rare earth free magnet for use in industrial motors
Scientists are working to find alternatives to rare-earth-based magnets that can function well in motors, because rare earth materials are expensive and can experience supply chain issues. One solution to this challenge was discovered by a team of researchers and industry partners led by scientists at the U.S. Department of Energy Ames National Laboratory. They developed a rare-earth-free bonded magnet that not only retains its magnetism at high temperatures, coercivity nearly doubles with a 100°C (212°F) increase from room temperature.
