Linear motors are becoming increasingly practical for general motion. Many are used for long strokes of a few feet or more. One new design, however, where the magnets move relative to a stationary ...

Never mind present-day’s bonny blather on the benefits of electric, hydrogen and biofuel power. How do you feel about magnets? Better make up your mind, stat; as of this morning, a company named ...

A research team led by Su-Min Kim and Jung-Goo Lee (Korea Institute of Materials Science; KIMS) has developed next-generation ...

China controls about 90% of the entire global supply of rare earth magnets, including their mining and refining. That means that most of the neodymium, dysprosium, and terbium that end up in EV motors ...

While electric vehicles certainly offer a host of eco-friendly advantages, they're not without some asterisks, one being the rare earth materials (and harmful mining thereof) used to make the magnets ...

Did you know GM invented the domestic, affordable permanent magnet? Before this neodymium-iron-boron magnet came along in 1984, electric motors, generators, audio speakers, hard-disk drives, and the ...

Electric vehicles are pushing scientists to tackle one of the biggest hidden energy drains inside electric motors: magnetic ...
