#8. A rectangular loop of wire is sliding as shown in the diagram, sliding with a speed V to the left on a friction-less surface. The loop slides through the gap between the poles of a magnet. Sketch a "velocity verses time" graph (time on the horizontal axis) that would represent the variation of the velocity of the loop. time LOOP speed #9. A loop of wire is caused to rotate in a magnetic field as seen in the diagram. The direction of rotation is counter-clockwise when looking toward M. The magnetic field is directed from the N-pole to the S-pole. Suppose a current meter were connected on the end of the wires A and B. Sketch a graph showing how the current will read (place time on the X -axis). M NV S A
