Formula and explanation
The magnitude of the induced electromotive force (emf) is equal to the negative rate of change of magnetic flux. Formula: E = - (d B)/(dt) Applicable Conditions: Closed loop or a segment of conductor in a changing magnetic field. Explanation: The negative sign embodies the directional meaning of Lenz's Law, indicating that the induced emf opposes the change in magnetic flux.
