According to Lenz's law, the induced current in a circuit will flow in such a direction as to create a magnetic field opposing the change in magnetic flux that produced it. In this case, the decreasing magnetic field into the page will induce a current in the loop in a clockwise direction, which will create a magnetic field out of the page to oppose the decreasing field into the page.
