Two very long parallel wires are a distance$$dd$$apart and carry equal currents in opposite directions. The locations where the net magnetic field due to these currents is equal to zero are

midway between the wires.a distance$$dd$/2$ to the left of the left wire and also a distance$$dd$/2$ to the right of the right wire.a distance$$dd$/22$to the left of the left wire and also a distance$$dd$/22$to the right of the right wire.a distance$$dd$$to the left of the left wire and also a distance$$dd$$to the right of the right wire.The net field is not zero anywhere.
