A new gravitomagnetic theory is used to investigate the trajectories of charged particles, spiraling in extended gravity and magnetic fields. In undisturbed atmospheres, collisions result in a slow top-trapping of ions with sufficient energies to escape that explains the extremely high temperature in coronas, radiation belts, etc. In disturbed media, force-free streams occur (merely due to the change of the pitch angle variation) that explain the occurence and disappearance of auroae or the surprising flare effect, that is the spiraling through a 'magnetic hole'.
