Consider a square current loop (L = 25 cm) that carries a current I = 5.6 A (Fig. P20.59). A constant magnetic field B = 0.25 T makes an angle u  30° with the direction normal to the plane of the loop and perpendicular to the line connecting points A and B.
(a) Find the total magnetic force on the loop.
(b) Assume the loop is attached to a rotatable rod at points A and B. Find the torque on the loop.
