Figure 1 shows a 2.0m 0.350 kg horizontal metal rod attached to two ropes, each of which makes an angle of 30 degrees with the horizontal. Each rope then drapes over a pulley and is attached to a vertical rod of mass m. Assume the pulleys have negligible mass. The is a 0.25T magnetic field in the region of the eod parallel to the xy plane, oriented 45 degrees from the long axis of the horizontal rod. When the horizontal rod is made to carry a current, suddenly the rod moves upward until the ropes holding it make an angle of 5 degrees with the horizontal. What was the value of the current?
