Electromagnetic Induction Laws

Faraday's Law

States that the induced EMF in a closed circuit is equal to the negative rate of change of magnetic flux through the circuit.

  • ε = -N × dΦ/dt
  • Larger flux changes produce larger EMF
  • Faster changes produce larger EMF
  • More turns increase the total EMF

Lenz's Law

Determines the direction of induced current: it flows to oppose the change causing it.

  • Explains the negative sign in Faraday's Law
  • Conservation of energy principle
  • Induced current creates opposing magnetic field
  • Natural resistance to change
