A metal bar with length LL, mass mm, and resistance RR is placed on frictionless metal rails that are inclined at an angle & above the horizontal. The rails have negligible resistance. A uniform magnetic field of magnitude BB is directed downward in the figure (Figure 1). The bar is released from rest and slides down the rails. Is the direction of the current induced in the bar from a to bor from b to a?
