Abstract:
A vehicle includes a ferromagnetic core having a winding, defining a gap, and configured to concentrate a net field in the gap. The vehicle also includes a controller programmed to flow a current in the winding such that an angle of the net field relative to a unipolar sensor in the gap is approximately zero and an intensity of the net field is at least twice that of a bi-directional field in the gap radiated from a conductor.
