For decades, permanent magnets have been one of the least questioned links in the electrification supply chain.

It's not surprising that the powertrains of electric cars differ quite a bit from traditional internal-combustion engines. Although they have fewer moving parts, the rare-earth magnets that help power ...

As NACFE has so well coined the phrase, we are in the "messy middle", a time when there are many solutions to decarbonize trucking. They start with improving fuel economy of diesel-powered vehicles, ...

It turns out the most abundant rare earth we have, cerium, can substitute for dysprosium when properly co-alloyed with cobalt. That's good news for the motor business. Share on Facebook (opens in a ...

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 ...

Two great minds in permanent-magnet-free motor design are fusing their know-how to create an even more capable inductive electric motor. Mahle and Valeo have teamed up to introduce what they call the ...

Rarely a week went by in 2025 without some newsworthy development related to rare earth elements, magnets, and electric motors. IEEE Spectrum was on top of the big ones, starting with the production ...
