Abstract
A wiring assembly having a conductor positioned about an axis in a helical-like configuration to provide a repetitive pattern which rotates around the axis. In one embodiment, when a current passes through the conductor, a magnetic field having an orientation orthogonal to the axis changes direction as a function of position along the axis.
