1.

What is Faraday’s law of electromagnetic induction? Write its expression. (OR) State the Faraday’s law of electromagnetic induction. Write the equation of this law

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
