Formula and explanation
For a coil of N tightly wound turns, the total induced electromotive force is the sum of the emf in each turn. Formula: E = - N (d B)/(dt) Applicable Conditions: The change in magnetic flux is the same for each turn. Explanation: This is an extension of Faraday's Law to the case of multiple loops.
