Does this mean we would be able to one day go to a shop and buy just the north pole of a magnet without any south pole?
Normally, if you try and cup a magnet in half between its poles, you just instantly create two new poles -NOT a monopole.
Originally posted by KazetNagorraSure, but a lot of technologies started out way too cumbersome to be used at home, look at the first computers, rooms full of relays, then tubes, taking 20 Kw or so to add 2 and 2.

Originally posted by Paul Dirac IIYeah, it does look like the media are overhyping this a bit. It's a pretty neat experiment, but what they actually show is that they can use these spinor BECs to simulate properties that a "real" monopole would have. They don't show the existence of magnetic monopoles.
That's pretty cool, although a link from that link reminds that "it should be stressed that our work does not tell anything about the existence of magnetic monopoles in the electromagnetic field”--i.e. the kind of fundamental particle Paul Dirac had in mind in the 1930s.
