Homework Help: Need help with a magnetic field question

  1. Oct 26, 2009 #1
    Ok the question is -- Why is the peak voltage generated by rotating a coil in a magnetic field proportional to the angular frequency of the rotation??

    The answer i believe is the higher the frequency--> the more rapid change of magnetic flux.

    can anybody concur this is correct and why the answer would not be higher frequency--> more rapid change of electric flux?

    The mechanism of induced current involves the force experienced by the free electrons in a conductor due to changing magnetic flux. It can be achieved by rotating the coil in the magnetic field. The change in electric flux does not contribute to the current in the circuit.
