11. A conductor of mass 40,0 grams per meter is hung by two wires in a 3.60 T field directed out of the page as shown. Source A Source B' a. Which source, A or B, should be switched on so that the magnetic field will deflect the wire upward, helping balance the conductor's weight? Explain. (ans: Source B-why?) b. How much current from the source would be needed so that the conductor would levitate, reducing the tension in the wires to zero? (ans: 0.11A)
