Starting outside the region with the magnetic field, a single square coil of wire enters, moves across, and then leaves the region with a uniform magnetic field3 perpendicular to the page so that the graph shown below represents the induced emf. The loop moves at constant velocity. As seen from above, a counterciockwise emf is regarded as positive. In which direction did the loop move over the plane of the page?
