Researchers have observed polar vortices in a ferroelectric material that appear to be the electrical cousins of magnetic skyrmions ... If these smoothly rotating vortex/anti-vortex topologies ...

This paper also explains why a simple rotating magnetic field doesn't induce mixing, and predicts the optimal wobbling angle of the magnetic field. Vortex ... with a permanent magnet, decant ...

If you made a motor out of a magnet, a wire coil, and some needles, you probably remember that motors and generators depend on a rotating magnetic ... of the poles in a permanent magnet.

Within the synchronous designs, there are permanent-magnet and current-excited motors. Asynchronous motors feature rotors that lag behind the rotating magnetic field produced by the stator.

ROUND AND ROUND Three permanently magnetized liquid droplets floating in oil spin in response to a rotating magnetic field, wrapping orange dye around themselves. Like conventional bar magnets, ...

Basically, a spiraling magnetic vortex has been found whirling around ... They found that it was being carried by a rotating magnetic wind, as opposed to the typical radial outflows expected ...
