7. Two wires lie in the z direction, spaced some distance apart. Each wire carries a current a) Make a sketch of the magnetic field lines that result from the wires in two cases: one in which the currents are traveling in the same direction, and one in which the currents are traveling in opposite directions. b) Describe the effect...
