1. An apparatus, comprising:
a support structure; and
an electrically conductive material arranged at the support structure to define a continuous path for electrical current to flow between a first location and a second location, the continuous path comprising:
a first path portion defined as a generally clockwise path for the electrical current to flow around a geometric center of the continuous path;
a second path portion defined as a generally counter-clockwise path for the electrical current to flow around the geometric center;
the first path portion and the second path portion together defining at least a first lobe and a second lobe, the second lobe adjacent and meeting with the first lobe at an inter-lobe region; and
the inter-lobe region having a radial-direction-reversal region at which one of the first path portion or the second path portion defined as the one of the generally clockwise path or the generally counter-clockwise path changes from being defined as a generally outward path along a portion of the first lobe for the electrical current to flow away from the geometric center to being defined as a generally inward path along a portion of the second lobe for the electrical current to flow toward the geometric center in the same one of the generally clockwise path or the generally counter-clockwise path.
