ight infinitely long current carrying wires are kept along z axis at the coordinates 0 a 0 and 0 a 0 respectively as shown in the figure The current in each of the wire is equal and along negative z axis into the plane of the paper The variation of magnetic field on the x axis will be approximately B B a c B X X b d a a B X
