Problem 4: You have a rigid rectangular conducting loop of width w (in
the y direction) and length l (in the x direction) being pulled in the x di-
rection at speed v. The loop is partially in a region of magnetic field, and
partially out; it is being pulled into the field. In the region that has magnetic
field, the field has magnitude B pointing in the z direction. What is the cur-
rent I induced in this loop? Assume the loop has total resistance R. What is
the force F with which the loop has to be pulled, given this induced current?
