The magnetic field through a wire loop, of radius $12 \ cm$ and resistance $8.5 \Omega ,$ changes with time as shown in the graph below. The magnetic field is uniform and perpendicular to the plane of the loop. Calculate the $\text{emf}$ induced in the loop as a function of time. Hence, find the induced emf in the time interval $(a) t = 0$ to $t = 2 s\ (b) t = 2 s$ to $t = 4s\ (c) t = 4s$ to $t = 6s.$
