    Abstract: Methods and apparatus for flux cancellation includes first and second inductors, wherein the first inductor is configured for coupling to a first energy source and the second inductor is configured for coupling to a second energy source. A layer of magnetic material is disposed between the first and second inductors, wherein the first and second inductors are configured such that, when driven with an oscillating current, magnetic flux generated by the first inductor is substantially canceled by magnetic flux generated by the second inductor in the layer of magnetic material.
