 Transmitter Take a Glass and whirl a wire on it 15 times after whirling a wire about three inches make a loop for center terminal and continue the process. Now take transistor BC547 or 2N2222 and connect its base terminal to one end of the copper coil, the collector terminal to the other end of the copper coil and now connect the emitter terminal to the negative (–ve) terminal of an 5v or 9v Power Adapter. The center terminal of the copper coil will be connected with the positive (+ve) terminal of an 5v or 9v Power Adapter. When then the receiver coil is placed 1 inch above the transmitter coil, then the LED will Glow. Receiver Make a 15 turn copper coil and connect a   Light to its ends. Wireless Power Transfer Circuit Working The wireless power transmission can be defined as the energy that can be transmitted from the transmitter to a receiver through an oscillating magnetic field.
