The magnetic field is increasing at a constant rate $\alpha$
through a circular loop of radius aandthe axis of magnetic field
coincides with axis of loop as shown in figure. Theresistance per unit
length of loop wire is $\rho$ . Choose correct option(s).

Show answer and solution

Magnitude of Induced emf =

A\frac{dB}{dt}

\varepsilon = \pi a^{2}\alpha

I_{PQRS\ } = \frac{a\alpha}{2\rho}

I_PR=0
