A rectangular loop is placed to the left of large current carrying straight wire as shown in figure. Current varies with time as $I=2t$. Find direction of induced current $I_{in}$ in the square loop.

Current $I$ will produce $\odot$ magnetic field passing through the loop. Current $I$ is increasing, so dot  magnetic field will also increase. Therefore, induced current should produce cross magnetic field. For producing cross magnetic field in the loop, induced current from our side should be clockwise.
