A circular loop of wire is in a region of spatially uniform magnetic field, as shown in $\textbf{Fig. E29.15}$. The magnetic field is directed into the plane of the figure. Determine the direction (clockwise or counterclockwise) of the induced current in the loop when (a) $B$ is increasing; (b) $B$ is decreasing; (c) $B$ is constant with value $B_0$ . Explain your reasoning.
