Both assertion and reason are individually correct statements.
Since induced emf,
thus due to negative sign, the total emf induced is equal to the time rate of decrease of the total magnetic flux linking the circuit. (The negative sign supports the Lenz’s law).
Since induced emf,
thus due to negative sign, the total emf induced is equal to the time rate of decrease of the total magnetic flux linking the circuit. (The negative sign supports the Lenz’s law).

Explanation:
Assertion (A):
- The total e.m.f. induced in a circuit is equal to the time rate of decrease of the total magnetic flux linking the circuit.
Reason (R):
- Changing magnetic field will induce an electric field.
Explanation of answer 'B':
- Both Assertion (A) and Reason (R) are true. When there is a change in the magnetic field enclosing a circuit, Faraday's law of electromagnetic induction states that an electromotive force (e.m.f.) is induced in the circuit. This induced e.m.f. is directly proportional to the rate of change of magnetic flux according to the formula: E = -dΦ/dt, where E is the induced e.m.f., Φ is the magnetic flux, and t is time.
- The Reason (R) provided is also correct. A changing magnetic field induces an electric field, which in turn creates an e.m.f. in a circuit. This phenomenon is the basis of electromagnetic induction and is a fundamental concept in electrical engineering.
- Therefore, both Assertion (A) and Reason (R) are true, but the Reason is not a correct explanation of the Assertion. The relationship between the induced e.m.f. and the rate of change of magnetic flux is a more direct explanation for the phenomenon observed in electromagnetic induction.
