Three identical coils $\displaystyle C_1, C_2$ and $\displaystyle C_3$ are closely placed such that they share a common axis. $\displaystyle C_2$ is exactly midway. $\displaystyle C_1$ carries current $\displaystyle I$ in anti-clockwise direction while $\displaystyle C_3$ carries current $\displaystyle I$ in clockwise direction. An induced current flows through $\displaystyle C_2$ will be in clockwise direction when
