• -The induced electromotive force or EMF in any closed circuit is equal to the time rate of change of the magnetic flux through the circuit.
• -The EMF generated is proportional to the rate at which flux is linked.
• - ε= ΔΦ/Δtime

-An induced current is always in such a direction as to oppose the motion or change causing it

• - ε=BLV
• - Φ= BAcosθ
• - ε=N x (ΔΦ/Δtime)
• - V= IR = BLV
