1. An electro-magnetic device comprising:

  • a low-profile magnetically permeable substrate;

    a first set of windings, magnetically coupled to the substrate having a first resultant force with respect to an alternating current input signal; and

    ,a second set of windings, magnetically coupled to the substrate, having a second resultant force with respect to a direct current input signal that is orthogonal in direction to the first resultant force;

    wherein the orthogonal resultant forces alters the permeability of the device, extending its operating range prior to saturation.
