Question

A circular loop of radius 20 cm and resistance 2 \(\Omega\) is placed in a time varying magnetic field \( \vec{B} = (2t^2 + 2t + 3) \text{ T} \). At \( t=0 \), for the plane of the loop being perpendicular to the magnetic field and, the induced current in the loop at \( t = 3 \text{ s} \) is \( \alpha/50 \text{ A} \). The value of \( \alpha \) is \dots (Take \( \pi = 22/7 \))}

Answer 1

Correct Answer: 44
