Lenz's law of electromagnetic induction states that
- A. e.m.f. is induced in a circuit whenever there is a change in the magnetic flux linked with the circuit.
- B. the induced current in a conductor is in such a direction as to oppose the change producing it
- C. the magnitude of the induced e.m.f. in a circuit is proportional to the rate of change of the number of lines of force linking the circuit
- D. a force is exerted on a current-carrying conductor in a magnetic Held
Correct Answer: B. the induced current in a conductor is in such a direction as to oppose the change producing it
