Introduction:
Wireless power transfer.
Wireless power transfer, is the transmission of electrical energy, without wires or a physical link. 
The technology of wireless power transmission, can eliminate the use of the wires and batteries, thus increasing the mobility, convenience, and safety of an electronic device for all users.
Wireless power transfer is useful to power electrical devices, where interconnecting wires are inconvenient, hazardous, or are not possible.
In this video we will learn how a wireless power transfer is done.

In a wireless power transmission system, a transmitter device, driven by electric power from a power source, generates a time-varying electromagnetic field, and transmits power across space to a receiver device.
Receiver extracts power from the field and supplies it to an electrical load.
