Hands On! Discovery Center Tesla Coil demonstration

A small demonstration of the Tesla coil, invented by Nikola Tesla, is a high-voltage, high-frequency air-core transformer that can transmit electricity wirelessly. It works by creating a rapidly oscillating electric current, which generates an electromagnetic field around the coil. When another electrically chargeable device is placed within this field, it can receive electrical energy wirelessly through electromagnetic induction. This principle demonstrated the potential for wireless power tran
