To Demonstrates the concept of electro-magnetism, by transferring electricity without any wires design by Nikola Tesla best project for wireless electricity . The Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in 1891. It is used to produce high-voltage, low-current, high frequency alternating-current electricity. Tesla experimented with a number of different configurations consisting of two, or sometimes three, coupled resonant electric circuits.
