A study is made of the radiative dynamics of a single charged particle in the fields of an oblique, rotating magnetic dipole and an attractive charge. It is found numerically that there exists a class of solutions corresponding to bounded orbits at a distance greater than c omega, where omega is the angular velocity of the magnetic dipole. In an independent-particle picture, particles started with different initial conditions within the basin of attraction of this class of orbits will eventually establish such a phase relationship with one another as to form a ring of particles around the rotational axis of the dipole. The existence of phase-locked dynamics for this system is also shown. These results suggest a possible structure of the outer magnetosphere of a nonaligned pulsar.
