The following diagram shows two parallel straight conductors carrying same current.Copy the diagram and draw the pattern of the magnetic field lines around them showing their directions. What is the magnitude of magnetic field at a point 'X' which is equidistant from the conductors ? Given justification for your answer.

In both the parallel straight conductors, the direction of the magnetic field lines will be equal as in both, the current is moving in the same direction.
Applying Right - hand thumb rule, we can draw the magnetic field lines around the given wires. As both the wires have a current flowing downward hence the direction of the magnetic field will be clockwise for both of them as shown in figure.
At the point 'X' the magnitude of the magnetic field is zero. By applying right hand thum rule, we know that every section of the wire contributes equal magnetic field lines. Point 'X' is at equidistant from both the conductors. Since no two magnetic field lines intersect, the field line appears as a straight line at the point X. So the magnitude will be zero.
