A new study by scientists at Scripps Institution of Oceanography at the University of California San Diego and the University of Leeds in England reveals that changes in the direction of the Earth’s ...

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 ...
