Solve a rotating-coil electromagnetism problem by deriving the induced emf from changing magnetic flux. Learn how coil area, number of turns, rotation rate, and magnetic field strength set the emf ...

Researchers have found that exposing a certain class of particles -- micron-sized beads endowed with a special magnetic sensitivity -- to a rapidly alternating, rotating magnetic field causes them to ...

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