1. An electrical system comprising:
a first body including two runners, the runners being a first runner and a second runner, wherein the first runner and the second runner are intertwined helically wound runners, wherein the first body is arranged in a first toroidal shape having a first centroid; a first conductive wire spirally wound around the first runner; a second conductive wire spirally wound around the second runner; a second body including two runners, the runners being a third runner and a fourth runner, wherein the third runner and the fourth runner are intertwined helically wound runners, wherein the second body is arranged in a second toroidal shape within the first centroid; a third conductive wire spirally wound around the third runner; a fourth conductive wire spirally wound around the fourth runner, wherein the first body and the second body are arranged such that the first toroidal shape and the second toroidal shape are concentric; and one or more alternating current sources, wherein the one or more alternating current sources are arranged to electrically couple with the first conductive wire, the second conductive wire, the third conductive wire, and the fourth conductive wire to supply alternating current, wherein the one or more alternating current sources are configured to induce one or more alternating currents through the first conductive wire, the second conductive wire, the third conductive wire, and the fourth conductive wire such that the one or more alternating currents create an electromagnetic field at or near at least one of the first centroid and the second centroid. |
