How Wireless Electricity Works:

How Wireless Electricity Works: Step One

A circuit [A] attached to the wall socket converts the standard 60-hertz current to 10 megahertz and feeds it to the transmitting coil [B]. The oscillating current inside the transmitting coil causes the coil to emit a 10-megahertz magnetic field.

How Wireless Electricity Works: Step Two

The receiving coil [C] has the exact same dimensions as the sending coil and thus resonates at the same frequency and, in a process called magnetic induction, picks up the energy of the first coil's magnetic field.

How Wireless Electricity Works: Step Three

The energy of the oscillating magnetic field induces an electrical current in the receiving coil, lighting the bulb [D].
