wireless electricity Project : Simple wireless electricity transmission project is an example of electromagnetic induction. It can be made by using simple components and easy circuit that are as follows
- 26 to 30 gauge copper wire (Magnet wire)
- One AA battery
- 2N2222 Transistor

Steps of Construction
The simple wireless electricity project consist of two parts that is Receiver and Transmitter
Making of Receiver
- Make a coil of 15 turns and connect LED to its ends.
Making of Transmitter
- Take a PVC pipe and make a coil of 7 turns on it, leave 3 inch wire to make a loop for central terminal and whirl the wire again 7 times.
- After completing the coil, three terminals will be obtained.
- Now take 2N2222 transistor, connect its base terminal to first end of coil and collector terminal to the last end of coil.
- Connect emitter terminal of the transistor to negative terminal of AA battery.
- The central terminal of coil will be connected with positive terminal of AA battery.
The transmitter is now ready. Place the receiver coil 1 inch above transmitter. You will observe glowing LED.
How does the project works
The wireless electricity transmission is achieved by oscillating magnetic field.
- At first, AA battery provide direct current source (DC).
- The Direct Current is converted into high frequency Alternating Current (AC) with the help of transmitter circuit.
- This alternating current energizes the transmitter coil which generates magnetic field.
- When secondary coil (receiver) is placed near to the primary coil, the changing magnetic field induces an alternating current in it.
