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. robert hoffman sweater weather fabric robert hoffmann concardis
