Faraday's Law Demonstration
This simulation demonstrates Faraday's Law of Electromagnetic Induction. Move the magnet through the coil and observe the induced current in the galvanometer.
When the magnet moves through the coil, the galvanometer needle deflects, showing induced current. The direction and magnitude of deflection depend on the magnet's motion.
Faraday's Law of Induction
1. A changing magnetic field through a coil induces an electromotive force (EMF).
2. The magnitude of the induced EMF is proportional to the rate of change of the magnetic flux.
3. The direction of the induced current opposes the change producing it (Lenz's Law).
• Speed of magnet movement (faster = greater current)
• Number of coil turns (more turns = greater current)
• Magnet strength (stronger magnet = greater current)
• Direction of movement (reversing direction reverses current)
