NEET Physics Faraday's Laws Assertion Reason Question
Assertion (A): Increasing the number of turns in a coil increases the induced emf during electromagnetic induction. | Reason (R): The induced emf is directly proportional to the rate of change of magnetic flux through the circuit.
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
The NCERT context states that the induced emf is given by dΦ/dt, and for a coil with N turns, it is N times this rate. Therefore, increasing N increases the induced emf, and the rate of change of flux is the reason.
