Electromagnetic Induction

Faraday's Law of Electromagnetic Induction

e = -N × dΦ/dt
  • e: Induced EMF
  • N: Number of coil turns
  • Φ: Magnetic flux
  • Lenz's Law

    The direction of induced current always opposes the change in magnetic flux that produced it.

    Self Inductance

    e = -L × di/dt

    Mutual Inductance

    e2 = -M × di1/dt
