Two long parallel transmission lines `40.0 cm` apart carry `25.0 A` and `75.0 A `currents. Find an locations where the net magnetic field of the two wires is zero if these currents are in
(a) the same direction (b) the opposite direction

Two straight infinitely long and thin parallel wires are spaced 0.2m apart and carry a current of 10A each. Find the magnetic field at a point distance 0.1m from both wires in the two cases when the currents are in the (a) same and (b) opposite directions.
