A metal bar of mass m = 0.067 kg and length L = 1.10 m is suspended from two light metal wires, as shown in the figure below. A uniform magnetic field of magnitude B = 0.32 T points due east. The bar is suspended along the north-south direction. The wires make an angle 250 with the vertical. In what direction should the current flow along the bar (north or south) and how much current needs to flow in order for the bar to be suspended in static equilibrium?
