NEET Physics Lenz's Law MCQ Question
Which of the following statements about Lenz's Law is correct?
Lenz's Law states that the induced current will always flow in the direction of the applied magnetic field.
The polarity of induced emf is such that it opposes the change in magnetic flux that produced it.
Induced currents can enhance the magnetic flux they oppose.
Lenz's Law is only applicable when the magnetic field is constant.
Correct Answer
Detailed Explanation
Lenz's Law indicates that the induced current flows in a direction that opposes the change in magnetic flux, as stated in the NCERT context. This ensures the conservation of energy within the electromagnetic induction process.
