No, actually it is a good thing for traveling toward a star, you have to decelerate, a magnetic field will allow you to decelerate with the target stars own wind. a magnetic sail will power your space craft as far as a solar sail would using star light and even faster because a magnetic sail will expand as it moves away from a star and allow you to get more thrust as you sail away! a magnetic sail doesn't have any problems with erosion from interstellar dust and can be furled and unfurled in a short time with no danger of damaging the sail. A magnetic sail that gets larger as you move away from the star would allow you get thrust a large distance from your sun, and a magnetic sail could interact with the galactic magnetic field to give some thrust. You could build up a large delta V close to a star and then coast to the next one.
