In the аrrаngement shоwn, а cоnducting bar оf negligible resistance slides along horizontal, parallel, frictionless conducting rails connected as shown to a 10-Ω resistor. A uniform 3.3-T magnetic field is perpendicular into the plane of the page. If L = 50 cm, what is the magnitude and direction of the current generated in the loop at the instant the bar is moving to the left at 7.3 m/s? In your work, and in your own words, explain why the current flows in the direction you selected.
