The magnetic field through a single loop of wire, $12\text{ cm}$ in radius and $8\cdot 5\ \Omega$ resistance, changes with time as shown in graph below (Figure 9). The magnetic field is perpendicular to the plane of the loop.

(a)
Find the induced emf for the time intervals 0 to $2\cdot 0\text{ s}$, $2\cdot 0$ to $4\cdot 0\text{ s}$, and $4\cdot 0$ to $6\cdot 0\text{ s}$.
(b)
Hence, plot induced current as a function of time.
