1. An apparatus comprising:
a support structure; and
a first electrically-conductive material arranged at the support structure to define a first continuous path for an electrical current to flow between a first location and a second location, the first continuous path comprising:
a first path portion defining a first generally-clockwise path for the electrical current to flow around a first axis;
a second path portion defining a first generally-counter-clockwise path for the electrical current to flow around a second axis;
a third path portion defining a second generally-clockwise path for the electrical current to flow around a third axis;
a fourth path portion defining a second generally-counter-clockwise path for the electrical current to flow around a fourth axis;
the first path portion, the second path portion, the third path portion, and the fourth path portion circumferentially arranged substantially in a first plane around a central axis, the third path portion opposite the first path portion and the fourth path portion opposite the second path portion;
respective ones of the first path portion, the second path portion, the third path portion, and the fourth path portion including a first inner-circumferential portion and a first outer-circumferential portion, the first inner-circumferential portion located closer to the central axis than the first outer-circumferential portion, a radius of curvature of the first inner-circumferential portion being greater than a radius of curvature of the first outer-circumferential portion;
a fifth path portion defining a third generally-clockwise path for the electrical current to flow around the first axis;
a sixth path portion defining a third generally-counter-clockwise path for the electrical current to flow around the second axis;
a seventh path portion defining a fourth generally-clockwise path for the electrical current to flow around the third axis;
an eighth path portion defining a fourth generally-counter-clockwise path for the electrical current to flow around the fourth axis;
the fifth path portion, the sixth path portion, the seventh path portion, and the eighth path portion circumferentially arranged substantially in a second plane around the central axis, the seventh path portion opposite the fifth path portion and the eighth path portion opposite the sixth path portion; and
respective ones of the fifth path portion, the sixth path portion, the seventh path portion, and the eighth path portion including a second inner-circumferential portion and a second outer-circumferential portion, the second inner-circumferential portion located closer to the central axis than the second outer-circumferential portion, a radius of curvature of the second inner-circumferential portion being greater than a radius of curvature of the second outer-circumferential portion.
