NEET Physics Lenz's Law MCQ Question
Which of the following statements about Lenz's Law is correct?
The induced current always flows in a direction that opposes the change in magnetic flux.
Lenz's Law only applies when the magnetic flux is increasing.
The polarity of the induced emf does not depend on the direction of the magnetic field.
Lenz's Law is irrelevant in cases of decreasing magnetic flux.
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 highlighted in the NCERT context.
