It used to be a staple of junior high physics class to build some sort of motor with paperclips or wire. A coil creates a magnetic field that makes the rotor move. In the process of moving, brushes ...

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 ...

Copper ions in solution moving between two electrodes in a magnetic field produce a swirling motion that can easily be displayed on an overhead projector. Place some pepper on the surface of the ...

Continuing headlines about superefficient electric drives might lead some observers to wonder about the future of three-phase induction motors. The truth is that induction motors aren’t going away any ...

General Motors has taken two more steps to make sure it has the raw materials for the transition from petroleum to battery power, this time lining up magnets for electric vehicle motors. On Thursday ...

We've hinted at the impressive power output of the BMW iX M60 motor in our First Look, but its fifth-generation electric motor technology deserves its own examination. That's because it's both ...

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 ...
