Abstract
A conductor assembly of the type which, when conducting current, generates a magnetic field or in which, in the presence of a changing magnetic field, a voltage is induced. According to an exemplary embodiment a conductor is positioned along a path of variable direction relative to a reference axis. The conductor has a width measurable along an outer surface thereof and along a series of different planes transverse to the path direction. The measured conductor width varies among the different planes. In one example, the conductor path is helical, positioned about the axis between turns of helical spaces, and the conductor width varies as a function of the azimuth angle.
