The figure shows, in cross section, four thin wires that are parallel, straight, and very long. They carry identical currents of i = 4.00 A inthe directions indicated. Initially all four wires are at distance d = 10.1 cm from the origin of the coordinate system, where they createa 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 30º? (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 30° back to its initialorientation?(a) Number(b) NumberiUnitsUnitsd04d02dx
