Lenz’s law of electromagnetic induction states that

e.m.f. is induced in a circuit whenever there is a change in the magnetic flux linked with the circuit

the induced e.m.f. in a circuit is proportional to the rate of change f the number of lines of force linking the circuit

the induced current in a conductor is in such a direction as to oppose the change producing it Amsar da ta dace

a force is exerted in a current-carrying conductor in a magnetic field.

the induced e.m.f. is proportional to the current producing the magnetic flux.
