Do charged particles have magnetic fields in the form of dipoles,I.e North and south poles? The reason I ask is, in some articles i have read it states that charged particles do indeed have magnetic dipoles and that a moving charge in an external magnetic field will experience a turning force due to its north pole being pushed in one direction and its south pole being pulled the other.
But, in other articles it states that the poles of an external magnetic field would niether repel nor attract a moving charged particle.
Clearly, both of these cant be true.
If a charged particles does possess a magnetic dipole and if it does experience a turning force in an external magnetic field, how is this known? is it something that has been tested and observed in practical experiments? or is it just an idea derived from theory?
If, on the other hand, a charged particle does not experience a turning force in an external magnetic field, how can we be certain that it does possess a magnetic field in the form of a dipole? Any takers?

When a charged particle is in motion it constitutes a current. Current produces magnetic field. On the other hand a magnetic dipole also give rise to a magnetic field. Thus we can combine these two facts and say that a moving charge behaves like a dipole.
A moving charge experience a force=F= q( v x B) where q= charge v= velocity B=magnetic field in which it is moving
In the above expression the multiplication sign stands for vector product
F= q v B sin theta where theta is the angle between 'v' and 'B'
