A magnetic field will apply a force on a single moving charge, and it will also exert a force on a current on which is a collection of moving charges. The force encountered by a wire of length l ...
Fleming’s Left Hand Rule can be used to determine the direction of the force, current or magnetic field. This force forms the basis of the electric motor. A current carrying conductor creates its own ...
In 1831, Michael Faraday discovered that subjecting a coil to a moving magnetic field induces a current. Today, electromagnetic induction powers most electric motors, along with a phenomenon described ...
