Two metal rods rest on metallic rails as shown, in the presence of a uniform magnetic field out of the page of strength B = 2 T. The rods start at the dotted and are moved in opposite directions as shown: one rod moves left at a constant speed of 2 m/s while the other moves right at a constant speed of 1 m/s. Take area vectors as pointing out of the page. (a) Determine the magnetic flux through the area bounded by the rails and the rods when xL = 0.2 m and xR = 0.1 m. (b) Calculate the magnitude and direction (CW, CCW) of the induced voltage on the loop created by the rails and the rods when xL = 0.2 m and xR = 0.1 m. (c) At the moment described in part (b) the resistance of the loop is 0.1 Ω. Determine the magnetic force (magnitude and direction) on each of the rods.
