In the figure, there is a uniform magnetic field of magnitudeB=1.7T and directed into the plane of the paper in the region shown. Outside this region the magnetic field is zero. A rectangular loop 0.20 m by 0.60 m and of resistance9? is being pulled into the magnetic field by an external force, as shown.

Part A)What is the direction (clockwise or counterclockwise) of the current induced in the loop?

B)Calculate the magnitude of the external forceF_{\rm ext}required to move the loop at a constant speed ofv= 3.9 m/s. The mass of the loop is 0.008 kg.
