Mike Klasco writes about Niron Magnetics' first commercial pilot plant in Minnesota. The opening of this 70,000 square-foot Minneapolis facility took place in October 2024 and is a key milestone in Niron Magnetics's path to scaled production of its Clean Earth Magnet technology and the company’s ability to bridge the acute supply and demand gap for permanent magnets. A significant step forward in the company's mission to produce sustainable, rare-earth-free permanent magnets.
