Question

The metal bar on the conducting rails is moving to the left. The magnitude of the uniform magnetic field is 0.84 Tesla. The magnetic field is directed out of the page. The length L is 0.70 m. The resistance R of the circuit is 3.70 ?. (a) If the induced current needs to be 0.68 A, what should be the induced emf? Keep 3 decimal places. (b) What should be the speed of the metal bar's motion? Keep 2 decimal places. (c) What are the direction of the INDUCED magnetic field at the center of the loop and the direction of the induced current in the loop? Select your answer from one of the following options. a. Induced field -- INTO page, induced current - Clockwise b. Induced field -- INTO page, induced current - Counterclockwise c. Induced field -- OUT of page, induced current - Clockwise d. Induced field -- OUT of page, induced current - Counterclockwise (d) What is the magnitude of the magnetic force on the metal bar? Keep 3 decimal places.
