As shоwn in Fig. 1.1, а 80 . 00 c m cоnducting rоd in good contаct with а frictionless conducting frame moves to the left with a constant speed 5 . 00 m s . The light bulb in the conducting frame has a resistance of 6 . 00 Ω . The entire system is immersed in a magnetic field of magnitude B → = 9 . 00 × 10 3 G which is inclined at 30 . 0 ° with respect to the frame as shown in Fig. 2. (a) Find the induced electromotive force on the circuit. (b) What is the direction and magnitude of magnetic force exerted on the rod? (c) Calculate the electrical power dissipated in the light blub. (d) To maintain the rod’s constant speed 5 . 00 m s , an external force must be applied on the rod. Determine the work done by the external force after the rod is moved to the left for 3 . 00 meters. If two straight frictionless conducting rails form a right angle and a conducting bar in contact with the rails starts at the vertex at t = 0 . 00 s and moves with constant velocity of 5 . 00 m s along them, as shown in Fig. 1.2, (e) what is the induced electromotive force in the circuit at t = 0 . 800 s if a magnetic field with B → = 9 . 00 × 10 3 G is directed into the page?
