Homework Help: Orientation of Magnetic Field and Coil

  1. May 20, 2012 #1
    1. The problem statement, all variables and given/known data

    Not technically a homework problem, has arisen as a point on my A-Level specification and I'm a little unsure as to how they are seeing this situation.

    "Relate qualitatively the instantaneous e.m.f. induced in a coil rotating at right angles to a magnetic field to the position of the coil, flux density, coil area and angular velocity;"

    I have attached two diagrams and am not sure which one they are describing. I think it's most likely to be diagram A. Could someone confirm this for me please?

    2. Relevant equations

    3. The attempt at a solution
