But, there may be another way, albeit a rather special case, where a magnet can not only be levitated, but locked in place using a rotating magnetic field. The video shows a demonstration of how ...

If you've ever watched a flock of birds move in perfect unison or seen ripples travel across a pond, you've witnessed nature's remarkable ability to coordinate motion. Recently, a team of scientists ...

Most EVs have permanent magnet synchronous motors (PMSMs), where the rotor has permanent magnets embedded in it that are ...

Researchers from Hanyang University have developed an innovative micropillar array capable of collective and rapid magnetic oscillations ... to changes in a rotating magnetic field, producing ...

Slip rings maintain constant contact with the same sides of the coil As one side of the coil moves up through the magnetic field, a potential difference is induced (created) in one direction.

While one might expect that the rotating magnetic field would just make these particles spin in place, instead the researchers observed them forming temporary chains of particles, which were able ...

A – The coil is at 0°. The coil is moving parallel to the direction of the magnetic field, so no potential difference is induced. B – The coil is at 90°. The coil is moving at 90° to the ...
