    What is the difference between the Magnetic Field Lines of the Dipole and Circular Current Carrying Wire at the centre?

    The farther away you move from the current loop in some arbitrary direction, the closer its field looks like that of a point dipole. If you have a circular current loop and move along the axis, then the field is identical to that of a point dipole in that is as a ##1/r^3## dependence.
