Faraday's Law: Induced EMF
Φ = B·A·cos(θ)
Magnetic flux through area
ε = BLv
Motional EMF (straight conductor)
📚 Key Concepts
  • Changing magnetic flux induces voltage
  • Faster changes create larger voltages
  • Lenz's Law: Induced current opposes change
  • More coil turns = higher induced voltage
  • Generators convert mechanical to electrical energy
🔬 Try This
  • Increase speed - watch voltage spike!
  • Try different modes to see various induction types
  • Add more coil turns for higher voltage
  • Observe how current direction follows Lenz's Law
  • Compare generator (rotating) vs transformer modes
