The induction coil provides very high voltages (several tens of thousands of volts) from a DC source. The principle is based on a step-up transformer comprised of a primary winding, a few tens of turns, and a secondary winding, hundreds of thousands of turns. To produce permanent sparks, it is necessary to cut the current flowing in the primary winding with a shaker (electromagnetic bell). The induction coil stands 6 inch tall, 11-1/2 inches wide, and 7 inches long. Each spark rod measures 5-1/4 inches long and 2-1/4 inches wide.
