This U.S. company’s new magnet could loosen China’s stranglehold on the supply chain

U.S.-made super magnets from Niron may be in audio gear next year, with EVs and wind turbines to follow. High-power magnets undergird an enormous amount of modern society. From high-end audio speakers to electric vehicles, wind turbines, and fighter jets, they are a vital component in much of the technology we touch every day. To make them requires mining and refining rare earth elements—a supply chain largely controlled by China.
