A conducting rod whose length is l = 1.60 m is placed on frictionless U-shaped metal rails that is connected to a lightbulb having a resistance of 4.00 as shown in the figure. The rails and the rod are in the plane of the page. A constant uniform magnetic field of strength 2.20 T is applied perpendicular to and out of the paper. (a) What are the magnitude and direction of the induced current in the circuit? (b) What is the magnitude of the external applied force needed to move the rod to the right with a constant speed of 6.00 m/s? B-field 1 out (
