Maximum EMF - parallel to field?

  1. May 20, 2012 #1
    for a rotating coil in a uniform magnetic field, why is the EMF maximum when the coil is PARALLEL to the field (i.e: flux linkage = 0)

    Induced emf = rate of change of flux linkage. This is greatest when the coil s passing through the parallel position

    why?

    Well...it goes from zero to something in a short space of time whereas when it is at 90degrees in the same space of time it doesn't change much......not very rigorous maths
