1. A system comprising:
a body including:
a first runner and a second runner that are intertwined,a first conductor wound around the first runner, wherein the first conductor includes a first pair of twisted conductive wires, wherein the first pair of twisted conductive wires includes a first wire and a second wire, anda second conductor wound around the second runner, wherein the second conductor includes a second pair of twisted conductive wires, wherein the second pair of twisted conductive wires includes a third wire and a fourth wire; and one or more current sources that provide a first alternating current to the first wire, a second alternating current to the second wire, a third alternating current to the third wire, and a fourth alternating current to the fourth wire, wherein the first alternating current and the second alternating current flow in opposite directions around the first runner, wherein the third alternating current and the fourth alternating current flow in opposite directions around the second runner, and wherein the system is configured to generate an electromagnetic effect responsive to the first, second, third, and fourth alternating current being provided. |
