Ames Researchers Develop Rare-Earth-Free Magnet

Researchers at the U.S. Department of Energy’s Ames National Laboratory have developed a rare earth-free permanent magnet suitable for industrial motors. This innovation addresses the high costs and supply chain vulnerabilities associated with rare earth elements like neodymium and dysprosium, commonly used in traditional permanent magnets.

The newly developed magnet maintains strong magnetic properties and resists demagnetization at the high temperatures typical in industrial motor operations. This advancement could lead to more cost-effective and sustainable permanent magnet motors, reducing reliance on rare earth materials and enhancing supply chain stability.
