NEET Physics Lenz's Law MCQ Question
What does Lenz's law state about the polarity of induced emf?
It produces a current that opposes the change in magnetic flux.
It generates a current that amplifies the change in magnetic flux.
It creates a current that has no effect on the magnetic flux.
It results in a current that randomly changes direction.
Correct Answer
Detailed Explanation
Lenz's law states that the polarity of the induced emf is such that it tends to produce a current which opposes the change in magnetic flux that produced it, as explained in the context provided.
