, '2d' being the distance the wires.
) at a distance '
' due to a current carrying conductor carrying current '
' is given by
' is an elemental length along the direction of the current flow through the conductor.
' is given by
' be the current carried by the top wire, '
' be the current carried by the bottom wire and '
' be the distance between them, then the direction of the magnetic field at 'P', which is midway between them, will be perpendicular towards the plane of the screen, shown by the 
symbol and that due to the bottom wire at 'P' will be perpendicular away from the plane of the screen, shown by 
symbol.
and
