Homework Help: Motional Emf

  1. Apr 9, 2008 #1
    Induced Emf

    For a loop of circular wire, there is a changing magnetic field running through it, but it is restricted to a region that is within the region of the loop of wire, so the field only runs through the loop of wire (it does not touch the loop of wire). Apparently, an emf is generated along the wire even though the magnetic field is not touching the wire. In the equations, the magnetic flux corresponds to the area of the of loop, so that would be the mathematical explanation, but how does that conceptually work? Would it be any different if the field were external to the wire instead?
