Permanent magnets sit at the heart of the green economy, from wind turbines and electric vehicles to smartphones and ...

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 ...

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 ...

We see our share of pitches for perpetual motion machines in the Hackaday tips line, and we generally ignore them and move along. And while this magnetic levitation motor does not break the laws of ...

UPDATE 10/20/2025: Niron Magnetics just broke ground on its commercial magnet production site in Sartell, Minnesota, which will become one of North America's largest magnet production it has expanded ...

How the switched reluctance motor's (SRM) architecture eliminates the need for magnets and rotor windings. Why SRMs are some of the most rugged and cost-effective motor technologies available. A look ...

This video is an animation of the principle behind PI’s magnetic linear motors. The magnetic linear motors correspond to a sequence of a number of voice-coil actuators; individual coils can be ...

A number of readers questioned the veracity of the technology presented in this article. To address their concerns, we did a follow-up, which can be found here. Permanent magnets are an integral part ...
