In Person
Niron Magnetics makes sustainable, high-performance permanent magnets for devices, motors, and generators. It uses Clean Earth Magnet technology to mass-produce magnets from abundant materials by altering the crystal structure of Iron Nitride through nanomaterial engineering and established metallurgical methods. This creates magnets that perform as well as or better than traditional magnets while reducing reliance on rare earth elements and lowering environmental impact, with a focus on stable, cost-effective manufacturing. The company differentiates itself by offering a greener, more affordable alternative to rare earth magnets, aiming to scale magnet production for widespread use in consumer, industrial, and automotive applications.

Niron Magnetics has begun site selection for a $1.8 billion iron-nitride magnet manufacturing plant in the United States. The company is working with Savills to identify locations based on transportation infrastructure, energy capacity, workforce availability and environmental priorities. The facility will span 1.6 million square feet, create over 700 jobs and produce up to 10,000 tonnes of iron-nitride permanent magnets annually. Construction is scheduled to begin in 2028, with the plant eventually supporting up to 2% of the global permanent magnet market. This would be Niron's second US facility. In September 2025, the company broke ground on a $169.7 million, 190,000-square-foot plant in Sartell, Minnesota, creating 175 jobs. That facility is expected to begin operations in early 2027.
Niron Magnetics has opened a Washington, D.C. office to advance US permanent magnet supply chain independence. The company manufactures high-performance Iron Nitride permanent magnets without rare earth elements, using domestically abundant iron and nitrogen instead. The move allows Niron to work directly with federal agencies on securing domestic magnet supply chains for motor vehicles, defence systems and consumer electronics. The company completed a two-year Department of Energy pilot project in late 2024 and broke ground on a 1,500-tonne-per-year manufacturing plant in Minnesota. Niron plans to build its first 10,000-tonne high-volume manufacturing plant. Luke Sandlin, former Senior Legislative Assistant to Majority Whip Tom Emmer, has joined as Director of Government Affairs to strengthen engagement with policymakers.
Niron Magnetics and FaitalPRO have developed professional audio loudspeakers using Iron Nitride permanent magnets that eliminate rare-earth dependencies whilst maintaining acoustic performance. The collaboration will showcase 8-inch and 10-inch loudspeakers at NAMM 2026 and ISE 2026 trade shows. The partnership combines Niron's Iron Nitride magnet technology, made from abundant iron and nitrogen, with FaitalPRO's engineering expertise. The project successfully demonstrated that rare-earth-free magnets can meet professional loudspeaker application standards. Niron Magnetics CEO Jonathan Rowntree stated the collaboration shows sustainable innovation need not compromise performance, allowing manufacturers to reduce rare-earth supply chain dependence. The company operates from its Minnesota facility and is currently the only producer of high-performance, rare-earth-free permanent magnets globally.
S&P Global shares how EVs could be shaped by changing economic trends. S&P Global Mobility reports that economic trends are pushing automakers to rethink their electric vehicle supply chains and certain aspects of vehicle design. "Amid shifting global trade dynamics, automakers are being forced to rethink supply chains for critical electric vehicle (EV) components," S&P's article states. "EV motors - long dependent on rare earth elements (REEs) - are now a strategic pressure point. Recent export restrictions from mainland China, which currently dominates the mining and refining of rare earth elements, combined with geopolitical uncertainty, have transformed automakers' dependence on REEs into a significant strategic vulnerability." In response, S&P has found automakers are either reducing or eliminating the use of REEs in their EV motors. "Cultivating robust supply chains for these alternatives will require close collaboration across Tier-1 and Tier-2 suppliers, as well as substantial in-house investment in advanced manufacturing capabilities," the article states. S&P predicts that the automakers who strengthen and diversify operations will mitigate cost volatility, reduce geopolitical risk, and accelerate EV adoption, according to the article. It points to recent actions by Renault and Honda as examples. "Renault is now actively seeking more cost-effective stator components from China while planning to manufacture the remaining parts internally, targeting full deployment by 2028," the article states. "Similarly, Honda's venture arm, Xcelerator Ventures, has invested in Enedym, a Canadian startup specializing in innovative switched reluctance motors (SRMs), a technology that eliminates the need for rare earth elements entirely." The article notes that Niron Magnetics has partnered with Stellantis to develop rare-earth-free EV motor designs. S&P expects that by 2030, General Motors and Volkswagen will incorporate induction motors in their EVs as opposed to magnet-based motors. In September, Ducker Carlisle wrote that the Trump administration's "One Big Beautiful Bill" would likely "extend far beyond regulatory compliance," and into the materials and processes used to manufacture vehicles. "With consumer EV incentives stripped away and federal agencies signaling a freeze on vehicle efficiency rules, the U.S. market faces a slowdown in both electrification and lightweight material adoption," the Ducker Calisle whitepaper states. It adds that OEMs could potentially use less magnesium, aluminum, and composites, slowing the growth trajectory for innovative solutions that do. "OEMs may choose to extend platform lifecycles, and this may lead them to revert to lower cost and heavier internal combustion engine (ICE) platforms," the paper says. "While EVs and global OEM programs may continue to support lightweighting trends and electrification, the U.S. market's reduced regulatory pressure may lead to stagnation in lightweighting needs."
