Figure 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 = 17.5 cm from the origin of the coordinate system, where they create a net magnetic field B.
(a) To what value of x must you move wire 1 along the x axis in order to rotate B counterclockwise by 32°?
(b) With wire 1 in that new position, to what value of x must you move wire 3 along the x axis to rotate B by 32° back to its initial orientation?
