Which of the following statements is not correct for electromagnetic induction?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → The magnitude of induced emf in a circuit is equal to the total change of magnetic flux through the circuit.
According to Faraday’s law, the induced emf is given by
$\varepsilon = -\frac{d\Phi}{dt}$
i.e., EMF depends on the time rate of change of magnetic flux, not the total change of flux.
