Abstract
Understanding pulsed electromagnetic systems is fundamental to modern power electronics, motors and energy recovery circuits. The Bedini Wheel provides an accessible experimental platform that combines mechanical rotation, permanent-magnet fields and precisely timed coil energization.
In this project a lightweight rotor carries multiple permanent magnets. As each magnet approaches a bifilar-wound stator coil, an optical or magnetic sensor triggers a MOSFET that briefly energizes the coil. The resulting magnetic pulse both propels the rotor and produces a high-voltage spike that is recovered into a secondary battery. The system illustrates magnetic flux interaction, resonance, back-EMF capture and the practical design of pulsed drive circuits.
It is an excellent final-year project for students of electrical, electronics, mechatronics and renewable-energy engineering who wish to explore electromagnetic principles through hands-on fabrication and measurement.
