To create the flux changes necessary to induce voltage in the secondary, the direct current in the primary is repeatedly interrupted by a vibrating mechanical contact called an interrupter.
An induction coil or spark coil is a type of electrical transformer used to produce high-voltage pulses from a low-voltage direct current (DC) supply.
They were widely used in x-ray machines, spark-gap radio transmitters, arc lighting and quack medical electrotherapy devices in early 20th century.
Developed beginning in 1836 by Nicholas Callan and others, the induction coil was the first type of transformer.
