Alternating (sinusoidal) Magnetic Field

  1. Feb 21, 2010 #1
    1. The problem statement, all variables and given/known data

    Imagine that a coil consisting of 75 turns of wire shaped as a circular loop with a radius of 12 cm is placed with its face perpendicular to the direction of an alternating (sinusoidal) magnetic field whose frequency is 60 Hz and whose maximum magnitude is 0.13 T (40 MN/C). Would this coil be able (in principle) to light a 120 V light bulb.

    2. Relevant equations

    I'm guessing I have to use Faraday's law of induction. Not sure what to do with the frequency though.

    3. The attempt at a solution

    I have no idea how to start, my textbook sucks and doesn't explain this at all. Thanks for any help.
