In my opinion "wobble" is a poor choice of a word. It is orbital motion, nothing more and nothing less.
The gravitational action of the planets causes the Sun to move in a complex looping path that sometimes carries it upwards of half a million miles from the barycenter, but as I pointed out earlier, the Sun "feels" nothing but a vanishingly small amount of tidal action. It is the nature of the rather gentle gravitational beast. I would be flabbergasted if this is enough to affect the electrodynamics of its innards significantly, and so far no one has offered a plausible effect from anything else related to the planets.
