Faraday's Law of Electromagnetic Induction
Formula: ℰ = -(dΦ_B)/(dt). Description: The magnitude of the induced electromotive force (emf) is proportional to the rate of change of magnetic flux through the loop. The negative sign indicates direction (Lenz's law). Conditions: Closed loop, changing magnetic flux.
