6 A long straight wire carries a current i Let B be the magnetic field at a point P at a distance d from the wire Consider a section of length 1 of this wire such that the point P lies on a perpendicular bisector of the section Let B be the magnetic field at this point due to this section only Find the value of d l so that B differs from B by 1
