question 70

Short Answer

Two wires, each having a weight per unit length of 1.0 × 10−4 N/m, are strung parallel, one 0.10 m above the other. If the wires carry the same current, though in opposite directions, how great must the current in each wire be for the magnetic field of the lower conductor to balance the weight of the upper conductor?
