High-performance magnets, which are critical for EV motors, typically depend on rare earth elements such as samarium, neodymium and dysprosium. These exotic materials are not only costly, but also present environmental and political challenges. Researchers from Tohoku University in Japan recently succeeded in producing a completely rare-earth-free high-quality magnet made of iron and nickel. The… Read more »
