A rectangular loop of sides a = 15 cm and b = 40 cm is in xy plane, with the sides of length b aligned with the x axis. A currentl': 5.0 A flows through the loop in the direction shown in the figure. The loop is in a uniform magnetic field :3. =40? mT. Determine the magnitude and direction of the force on each of the four sides of the loop (top, bottom, left, right)
