A cooktop heating element includes a helix shaped induction coil. The helix shaped induction coil includes a first array of parallel current-carrying wires and a second array of return current carrying wires. A magnetic shielding sheet is placed between the first array of parallel current-carrying wires and the second array of return current carrying wires. The magnetic shield sheet magnetically shields the first array of parallel current-carrying wires from the second array of return current carrying wires.
