NEET Physics Faraday's Laws Assertion Reason Question
Assertion (A): The induced emf in a coil is zero when there is no change in magnetic flux through it. | Reason (R): The induced emf is proportional to the time rate of change of magnetic flux through the coil.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false, but R is true.
Correct Answer
Detailed Explanation
According to Faraday's law, the induced emf is given by the time rate of change of magnetic flux (dΦ/dt). If there is no change in magnetic flux, the induced emf is zero. Therefore, R explains A.
