A new kind of magnet for industrial motors | R&D 100 Winner

AMES National Laboratory

A magnet that gets stronger with heat??? This tech won gold in the R&D 100 Awards. Meet the MnBi magnet — a rare-earth-free breakthrough that defies the rules of magnetism. While most magnets lose strength at high temps, MnBi gains coercivity (resistance to demagnetization) as it heats up — up to 200°C! ?? ? No rare earth elements = fewer supply chain issues & lower cost ? Performs in extreme heat = perfect for EV motors & industrial machines ? Reliable & sustainable = great for clean tech a…
