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 apparatus stands 6-1/2 inches tall, 12 inches wide, and 7 inches long.
