Abstract: A power carrier transmits an electrical current to and from a load. The carrier has a set of wires carrying electricity in parallel to the load and another set of wires carrying the electricity back in parallel from the load. The wires are organized with equal numbers of wires form each set grouped around a junction alternatingly, so that as a result the magnetic fields created by the electricity flowing through the two sets of wires cancel each other out in the junction. The carrier may have several junctions in a rectangular matrix pattern or hexagonal close-packed pattern, or other patterns, e.g., octagonal, which may be combined with junctions with different numbers of wires. The resulting power carrier has a reduced external magnetic field.
