Question about currents ?

  1. Feb 14, 2016 #1
    Can a moving magnetic field create eddy currents in a conductor ?
    Moving a magnet in and out of a solenoid makes a current flow in the solenoid. I know that a changing magnetic field induces emf in a conductor but what about a moving magnetic field ? Are eddy currents present in the solenoid (above) ?

    There has to be a relative motion between the field and the conductor for induction of emf. In induction motors, the stator field is moving, which induces emf in the rotor bars.
