Have you ever wondered how electricity is created in power plants? In this exciting STEM project, a wheel with magnets spins near coils of wire, producing electricity that can light up LEDs. This experiment shows how motion and magnets generate electrical energy, just like real generators used in wind turbines and power stations.

Demonstrates electricity generation through magnetic motion and rotating components.

Science Concept Behind It

This project works on Electromagnetic Induction.

• Magnets create a magnetic field
• Moving magnets near a coil changes the magnetic field
• This change pushes electrons, creating electricity

Motion Energy → Magnetic Effect → Electrical Energy

Materials Required

• Strong magnets
• Copper wire coil
• LED light
• Rotating wheel/disc
• Wooden base
• Screws or glue
• Connecting wires
• Motor or hand crank

Step-by-Step Working

Step 1: Attach Magnets

Fix magnets around the wheel so they spin in a circle.

Step 2: Place Coil

Keep the copper coil close to the spinning magnets (without touching).

Step 3: Connect the LED

Attach coil ends to the LED.

Step 4: Spin Wheel

Rotate using a hand or a motor.

Step 5: Generate Electricity

• The magnetic field keeps changing
• Electric current is produced
• LED lights up

Faster spin = brighter light
