Wireless power transfer (WPT), wireless power transmission, wireless energy transmission, or electromagnetic power transfer is the transmission of electrical energy from a power source to an electrical load, such as an electrical power grid or appliance, without the use of conductors like wires or cables. Its applications include electric toothbrush chargers, smartcards, chargers for implantable medical devices like artificial cardiac pacemakers, and inductive powering or charging of electric vehicles like ,trains , buses, develop wireless systems to charge mobile and handheld computing devices such as cellphones, digital music players and portable computers without being tethered to a wall plug.

The Tesla coil is an electrical resonant transformer circuit designed 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. Today their main use is for entertainment and educational displays, although small coils are still used today as leak detectors for high vacuum systems.
