WebThe induced emf in a coil is equal to the rate of change of flux linkage. The flux linkage is the product of the number of turns in the coil and the flux associated with the coil. The formula of Faraday’s law is given below: ε = − N Δ ϕ Δ t. Where ε is the electromotive force, Φ is the magnetic flux, and N is the number of turns.
