a. If a South pole moves toward the loop in the plane of the page, in what direction is the induced 2. current? (10 points) b. If a coil is expanding in a magnetic field pointing out from the page, in what direction is the induced current? (10 points) c. A wire loop is being pulled towards a current-carrying wire. What is the direction of the induced current in the loop? (20 points) d. To make the rod move to the right at speed v, you need to apply an external force on the rod to the right. If l= B cm, B filed is D/50 T, v= B/5 m/s and R= D . Determine the current I and the direction? (35 points)
