A conducting rod (L = 2.0 m) is moved along two conducting rails within a magnetic field (B). The rails are hooked up to a light bulb. The resistances of the rails and the rod are negligible, but the light bulb has a resistance of 100 Ω. The rod is moved at a velocity (v) of 10 m/s in the direction indicated. It induces a current (I) in the circuit as indicated in the figure. The magnetic field has a magnitude of 2.0 T and the direction is indicated in the figure. What is the magnitude of the induced electromagnetic field (EMF; ε)?
