Circuit Diagram Explanation
We need required items and assemble according to project. When we flow current in one coil and bring near second coil , the second coil has induced current and current flow in copper wire in 2nd coil and the LED blink(on) . This phenomenon is known as MUTUAL INDUCTION. This project is very cheap and everyone is make this project. This concept is use in our daily life. Like WIRELESS CHARGING in smartphone.
