I think they call them monopoles, and as yet, they don’t seem to be able to create them. Take a bar magnet, it has a north and south pole. Keep cutting the magnet in half and you never get to either north or south. At least, that’s how I remember it.

Whether one is ever created or not, there would be such a thing as a half a monopole, wouldn't there?
