Answer:

Lenz’s law states that induced electromotive force with different polarities induces a current whose magnetic field opposes the change in magnetic flux through the loop in order to ensure that original flux is maintained through the loop when current flows in it.

The Lenz Law is reflected in the formula of Faraday’s law. Here the negative sign is contributed from Lenz law. The expression is –

$Emf=−N(ΔϕΔt)$

Where,Emf is the induced voltage (also known as electromotive force).

N is the number of loops.

$Δϕ \: Change \: in \: magnetic \: flux.$

$Δt \: Change \: in \: time.$

$<body bgcolor=black><marquee direction="up">Lenz's law states that when the north pole of the bar magnet is approaching the coil, the induced current flows in such a way as to make the side of the coil nearest the pole of the bar magnet itself a north pole to oppose the approaching bar magnet.$
