Two long straight parallel wires, separated by 6.00 cm, are perpendicular to the plane of the page as shown in the figure. Wire "a" carries a current of 26.0 A into the page. What must be the current (magnitude and direction with respect to "a") in wire "b" for the resultant magnetic field at point P to be zero? Wire a, wire b and the point P are on a straight line and wire b is 17.00 cm from P.
