Chapter 21, Problem 41P

* A rectangular wire loop is moving with constant speed through a region of uniform B field that points into the page (Figure P21.41). The longer side of the loop is twice the width of the magnetic field region. Draw a qualitative graph that shows how the induced current in the loop depends on time during the period in which the loop moves from the position shown in the figure to the position where the left side of the loop exits the magnetic field. Assume that a counterclockwise direction of the current is positive.
