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 field. Once you know how it works, the concept is ...

For more than a century, engineers have chased new ways to turn the planet’s natural motions into usable power, from tides to ...

Physicists have demonstrated the spin pumping effect in magnetic layers for the first time experimentally. The behavior of the spin pumping had previously only been predicted theoretically. Scientists ...

A spin measured by an observer in a rotating frame appears to precess faster or slower depending on Ω, the rotational angular frequency of the frame. This can be thought of as arising from an ...

Physicists have observed the Zel’dovich effect in an electromagnetic system – something that was thought to be incredibly difficult to do until now. This observation, in a simplified induction ...
