A section of copper wire with resisivity, p = 1.70 x 100 m, and total resistance, R = 10.0 2, is formed into a N = 70-turn rectangular coil that is a = 11.1-cm wide, and b = 19.7-cm long. The coil, which is rated for a maximum current, lUL = 8.98 A, is placed in the uniform magnetic field, B = 3.00 T, between the poles of a powerful magnet, and rotated at constant angular speed, w = 23.0 rad/s, as shown in the animation.
