Induction Coil

An induction coil or "spark coil" (archaically known as a Ruhmkorff coil after Heinrich Ruhmkorff) is a type of disruptive discharge coil. It is a type of electrical transformer used to produce high-voltage pulses from a low- voltage DC supply. To create the flux changes necessary to induce voltage in the secondary, the DC current in the primary is repeatedly interrupted by a vibrating mechanical contact called an interrupter. Developed beginning in 1836 by Nicholas Callan and others, the induction coil was the first type of transformer.The term 'induction coil' is also used for a coil carrying high-frequency AC producing eddy currents to heat objects placed in the interior of the coil, in induction heating or zone melting equipment
