Using a laser to stimulate a photocurrent and a magnetic field to control it, researchers have devised a scheme for measuring a current’s flow stream. Why there’s a need to assess current-flow ...

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 ...

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 ...

The Sun has a powerful magnetic field created by the movement of hot, charged gases inside it. The magnetic field lines stretch out from the Sun's interior to the surface and into the solar atmosphere ...

Magnetic oil droplets with switchable rolling and swimming modes enable adaptive navigation, particle transport, and control in chemically varied environments. (Nanowerk Spotlight) Artificial ...
