According to Wikipedia:

Tesla coil is an electrical resonant transformer circuit invented by Nikola Tesla around 1891. It is used to produce high-voltage, low-current, high frequency alternating-current electricity.

Tesla coils can produce higher voltages than other artificial sources of high-voltage discharges,electrostatic machines. Tesla experimented with a number of different configurations consisting of two, or sometimes three, coupled resonant electric circuits.

Tesla used these coils to conduct innovative experiments in electrical lightingphosphorescencex-ray generationhigh frequency alternating current phenomena, electrotherapy, and the transmission of electrical energy without wires. Tesla coil circuits were used commercially in sparkgap radio transmitters for wireless telegraphy until the 1920s, and in pseudomedical equipment such aselectrotherapy and violet ray devices. Today their main use is for entertainment and educational displays.
