DIY Electromagnetic Swing Experimental Electronic Kit

A DIY Electromagnetic Swing Experimental Electronic Kit is an educational electronics project that demonstrates how electromagnetism can keep a pendulum (swing) moving without being pushed by hand.

How it works

The kit typically includes:

• A PCB (printed circuit board)
• Electromagnetic coil
• Hall-effect sensor or reed switch
• Transistor or MOSFET
• Resistors, capacitors, and LEDs
• Power supply
• Swing arm or pendulum with a small magnet

Working principle:

1. The pendulum starts swinging.
2. As the magnet passes the sensor, the sensor detects its position.
3. The circuit briefly energizes the electromagnet.
4. The electromagnet gives the pendulum a small push.
5. This repeats every swing, compensating for energy lost to air resistance and friction.

This demonstrates:

• Electromagnetic force
• Magnetic fields
• Electronic switching
• Oscillation
• Energy conversion
