|When astronomers study sunspots they occasionally notice that there only seems to be one magnetic pole. But I thought that monopoles didn't exist that we know of. What's going on?
While a sunspot may have only one magnetic pole associated with it, there is sure to be an equal but opposite pole somewhere else in the sun. Probably it's located deep inside the sun or somewhere else on the sun's surface. Like one end of a long bar magnet, the sunspot looks like a single pole, but it's really connected to an equal but opposite pole.
