Do two distinct poles actually exist at two nearby points in a magnetic dipole?

No. In a magnet, even the concept of poles is relative. Poles are instantaneous and are defined as the points where the magnetic fields are assumed to originate and to end. For a real magnet, which is equivalent to a magnetic dipole, there should be a distance in between the two poles in order to create magnetic field.


The magnetic moments can be defined as the strength of a magnet, that enables the magnet to produce a magnetic field.


For a magnetic pole strength m, and distance in between the two poles as L, the magnetic moment M will be,



Since the value of L is Zero in a dipole with nearby points, there won’t be any magnetic moments, and hence there would not exist a magnetic dipole with a magnetic field.
