The Lenz's law refers to:
Correct answer: A. Induced current
- A. Induced current
- B. Induced emf
- C. Both (a) & (b)
- D. None of these
Explanation
Lenz's law refers to Induced current.Lenz's law states that the direction of the induced electromotive force (emf) and the induced current in a conductor or loop will be such that they oppose the change in magnetic flux that produced them. Therefore, Lenz's law specifically refers to the direction of the induced current in response to changes in the magnetic flux passing through a conductor or loop.

About Electromagnetic Induction
Changing magnetic flux induces an emf according to Faraday's law, while Lenz's law gives the direction that opposes the change producing it. Transformers apply induction between coils to step alternating voltage up or down, with turns ratio, current transformation and energy losses determining practical operation.
