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 ? Give justification for your answer.
The point X is equal distance from the two parallel straight conductors the magnitute of magnetic field is zuw as the magnetic field produced by the two wires will be equal so as we know that two magnetic field lines never intersect each other and they would form a straight line at the point X as it is equidistant from them.
