1 Answer

Answer :

Lenz’s Law: It states that the direction of electromagnetically induced emf is such that it always opposes the main cause of its production.

Or

It is expressed by equation

E = - N (dΦ/dt) volts

Where – sign indicate the direction EMF is induced opposite to rate of change of flux.
