Question

State and explain Lenz’s law in the light of principle of conservation of energy.

Answer 1

Lenz’s law : The direction of the induced current is such as to oppose the change that produces it.

The change that induces a current may be (i) the motion of a conductor in a magnetic field or (ii) the change of the magnetic flux through a stationary circuit.
