Answer:
The magnitude will be zero Oersted.
Explanation:
The current conveying straight conductor includes magnetic field as concentric circles following right-hand thumb rule.
The concentric circles of the two wires will intersect/ overlap at point X. But their direction will be inverse. So they will offset/ cancel the effect of each other and the magnitude/ extent of this magnetic field at X will be zero Oersted.
