Two infinitely long parallel wires carry currents of magnitude`I_(1)` and `I_(2)` and are at a distance 4 cm apart. The magnitude of the net magnetic field is found to reach a non-zero minimum values between the two wires and 1 cm away from the first wire. The ratio of the two currents and their mutual direction is
