A star can only provide enough propulsion to get your mag field space craft may be two light years away, but after that the sun will be too distant to provide any real magnetic propulsion, and that's saying the mag field can be lengthened to a million miles in diameter.

Gardamorg, once you achieve a velocity in space you keep it until something else acts on you. And at least theoretically a magnetic sail could be a million miles in diameter. But it wouldn't need to be, once you had achieved your velocity you could coast to the end of the universe if you wanted but I would prefer to coast to the next star and decelerate into orbit around that star. Power to generate the sail could be generated by a nuclear reactor. All this technology could be done now, nothing new needs to be discovered for it to work.
