Wireless Power Transfer System
The concept of wireless electricity, first demonstrated by Nikola Tesla over a century ago, is now a reality in countless devices. This project demonstrates the principle of wireless power transfer using electromagnetic induction. A simple oscillator circuit drives a transmitter coil with AC current at high frequency. This creates an alternating magnetic field around the coil. When a receiver coil is brought within this field, the changing magnetic flux induces an EMF in the receiver coil – transferring power without any physical connection.

Electromagnetic Induction
Electromagnetic induction is the production of an electromotive force across an electrical conductor in a changing magnetic field. First discovered by Michael Faraday in 1831, this principle forms the basis of transformers, inductors, and wireless power transfer. In this project, a transistor-based oscillator generates high-frequency AC current in the primary coil. The magnetic field links with the secondary coil, inducing voltage that can light an LED or charge a battery – demonstrating contactless power delivery.
