The vector potential for an almost point like magnetic dipole located at the origin is μsin - where (r,0,0) denote the spherical polar coordinates and is the unit vector A= 4πr² along. A particle of mass m and charge q, moving in the equatorial plane of the dipole, starts at time =t=0 with an initial speed , and an impact parameter b.
