In practice, can very high magnetic fields significantly alter the dynamics of an astronomical-scale bodies?

The direct effect of magnetic fields on the dynamics (as in the movements, trajectories etc of the bodies themselves, rather than lower-level phenomena like stellar winds and atmospheric degradation) ...
