B-field phase question

  1. May 12, 2005 #1
    Imagine I take a pair of helmholtz coils and apply a DC current, modulated by a much smaller AC current so that the B-field between the coils varies sinusoidally about some fixed value. Will the AC component of B be in phase with the AC voltage, or the AC current?

    Waitaminute, it's obviously in phase with I. Currents induce magnetic fields, not voltages. Sorry guys, think it's past my bedtime...
