They say all you need is love, but in fact, you need a lot of magnets, too. Computers, appliances, electric generators and cars are powered by permanent magnet motors. Yet, most of the permanent magnets that make our modern life possible rely on rare earth materials, which are expensive, unsustainable and typically mined and processed in China.
To fix this bottleneck, Minneapolis-based Niron Magnetics is producing a new kind of magnet that uses two abundant raw materials: iron and nitrogen. By taking rare earths out of the equation, Niron’s Clean Earth Magnets® provide superior cost and supply chain stability to the countless manufacturers that depend on reliable access to high-powered magnets.
Why it matters: According to Niron, the demand for rare earths for critical magnets is outstripping the supply, and the problem is only getting worse.
- “When you look at the amount of magnets that are needed over the next 10 years, it’s triple the amount that are available today,” said Niron Magnetics CEO Jonathan Rowntree.
- “There’s only enough rare earth materials to double the amount of rare earth magnets manufactured every year. So there’s going to be this big imbalance later this decade. We’re well positioned to [meet] the shortfall of permanent magnets using iron nitride technology.”
