A magnetic field B, directed along the z-axis, varies with time T as shown in the figure. A planar conducting loop is in the magnetic field. The magnetic field is perpendicular to the plane of the loop.

Select the appropriate description for the magnitude of the EMF induced in the loop (EMF-mag) and for its direction (EMF-dir) at the indicated times. Select a response for each statement.
