If earth’s magnetic poles “slowly flip” over a few hundred or thousand years, (if the Aurorae Borealis & Australis follow along and when magnetic poles migrate to equator) will only one aurora be visible on the shaded side of earth?

Is there a smallest possible size of an arc you could spin a perfectly precise laser pointer on that at a long enough distance, the end point of the laser beam would appear to “hop” as opposed to smoothly move across a “perfectly” smooth surface?
