Question

(B) Faraday's law of electromagnetic induction states that the magnitude of the induced $e.m.f.$ $(\varepsilon)$ in a circuit is equal to the negative

Vedclass · Accepted Answer

The magnitude of induced $e.m.f.$ produced in a coil is directly proportional to the rate of change of magnetic flux.

Vedclass · Answer

(B) Faraday's law of electromagnetic induction states that the magnitude of the induced $e.m.f.$ $(\varepsilon)$ in a circuit is equal to the negative rate of change of magnetic flux $(\Phi_B)$ through the circuit.Mathematically, it is expressed as $\varepsilon = - \frac{d\Phi_B}{dt}$.The negative sign indicates Lenz's law, which describes the direction of the induced current. However, the law itself primarily defines the magnitude of the induced $e.m.f.$ as being directly proportional to the rate of change of magnetic flux. Therefore, option $B$ is the correct statement regarding Faraday's law.

According to Faraday's law of electromagnetic induction:
