Chapter , Problem 24(choose chapter or problem)
Figure 29-52 shows, in cross section, four thin wires that are parallel, straight, and very long. They carry identical currents in the directions indicated. Initially all four wires are at distance d ! 15.0 cm from the origin of the coordinate system, where they create a net magnetic field . (a) To what value of x must you move wire 1 along the x axis in order to rotate counterclockwise by 30? (b) With wire 1 in that new position, to what value of x must you move wire 3 along the x axis to rotate by 30 back to its initial orientation?
