What effect do tidal interactions have on magnetic fields?

[newtonian]

For example, magnetic fields on our sun involve ions in motion. <br /><br />Tidal interactions cause motion of fluids, and I suspect gases also.<br /><br />Hence my qjuestion.<br /><br />As an extreme example, if a Jupiter-like planet is orbiting a star in an elliptical orbit taking it very close to the star - what degree of effect would this extreme scenario have on said star's magnetic fields?
