In the given diagram two long parallel wires carry equal currents in opposite direction. Point O is situated midway between the wires and the $XY$- plane contains the two wires and the positive Z-axis comes normally out of the plane of paper. The magnetic field $B\ at\ O$ is non-zero along [image:4_image85.emf]

(d) As the currents are in opposite directions, the magnetic field induction due to current in each wire will add up at $O$. The direction of magnetic field is perpendicular to $X - Y$ plane and is directed inward $ie,$ along negative Z-axis.
