Answer» 1. The induced EMF generated in a closed loop is equal to the rate of change of magnetic flux passing through it. Induced EMF = Change in flux / time ε = ∆Φ / ∆t 2. Let Φ0 be flux linked with single turn. If there are N turns of the coil, the flux linked with the coil is NΦ0 . ∴ ε = NAΦ0 / ∆t |
