and it may soon be possible to build permanent magnets as strong as neodymium magnets, but without any rare earth metals. In fact, the only thing needed to make them is iron and nitrogen ...

But rather than using alternating currents through large inductors, [Tim] put 40 neodymium magnets with alternating polarity around the circumference of a large MDF disk. When driven by a drill ...

In mid-January, a top United States materials company announced that it had started to manufacture rare earth magnets. It was important news—there are no large U.S. makers of the neodymium ...
