Consider two long parallel wires which are perpendicular to the pla

ne of the paper $($i$.$e$.,$ the x$-$y plane$).$ Both wires carry the same current, I. Wire #$1$ intersects the plane a distance a above point O and wire #$2$ intersects the plane a distance a below point O$.$ Point C is equidistant from both wires and is a distance a from point O$.$
