A research team led by Kuang Guangli and Jiang Donghui at the High Magnetic Field Laboratory of the Hefei Institutes of Physical Science of the Chinese Academy of Sciences (CHMFL), has developed a ...

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 ...

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 ...
