1) (25 points) Consider a loop of wire in the shape of an isosceles right triangle. Denote the
height to the base by h . The loop is placed near an infinitely long wire carrying current I , as
shown in the figure. The distance from the long wire to the base of the loop is d . Find (i) the
magnitude of the magnetic flux through the loop and, (ii) assuming the loop has resistance
R , the current in the loop as it moves away from the long wire with speed v .
