A coil of wire with 20 loops is part way into a region of constant magnetic field of strength 0.5 T, perpendicular to the loop, with the flux passing down through part of the loop into the paper (see diagram). The width of the loop L = 30 cm, and the coil is pulled out of the field to the right with a force of 200 N. The resistance of the coil is 0.6 12. - B = 0.5 T Coil (20 loops) X X Х Х x x F F XIX u х L ws Х X х х x Х Х x x х (a) Calculate the induced current in the coil. Also state or show its direction in the loop. [5] (b) Calculate the speed at which the coil is pulled. [8] (c) Calculate the electrical power dissipated in the coil and the mechanical power required to move the coil. Hence, show that they are equal. 8
