b) Consider two metal bars 1 and 2 , which are able to move on fixed rails as shown, in the presence of a uniform magnetic field B0. Initially, Bar 2 is moved with a constant velocity v as shown, while Bar 1 is held in place with brakes. At t=0, when the distance between the two bars is d the brakes on Bar 1 are released so that it can move. The intensity of the magnetic field is ∣B0∣ and the separation between the fixed rails is I. Would the motion of Bar 2 with a constant velocity v have any effect on Bar 1 ? If so, qualitatively describe the effect.
