A magnet always has a north and a south pole. Even if a magnet is cut in half down to the atomic level, magnetic fields are bipolar. However, in 1931 it was theorized that there are natural monopoles which help explain some of the peculiarities of magnetism. This has never before been tested because scientists have not been able to create monopole elementary particles in the lab that could be studied individually - until now.  The research was led by David Hall of Amherst College and the results were published in Nature.

Unfortunately this is another case of science journalism exaggeration. If you read the original Nature article, or some other reports of this same work in other news articles, you will see that what the researchers actually created is an _analog_ to a true Dirac monopole. They have not reached the "holy grail" of the true monopole. Nice work overall, though. Too bad it is bound to be so badly misunderstood.

As I understand ferromagnetism, seen in pms and ems, there is no such thing like 2 poles, but instead there is 1 direction. That, of course, has a source and a destination. It reqires both to be that direction.
At the other hand there may be unipolar reaction to a pm, regardless of polarity, as seen in diamagnetism.
A nice experiment is to make some graphite powder from a pencil, then put that on a paper, move a PM underneath the paper, some powder particles will jump around visibly.
Unipolarity or monopolarity doesn't seem to be the holy grail to me.  It isn't the same as attracting as long as it is getting closer, but let go when it is moving away. That, although unlogical, would be the holy grail indeed.
You may however build yourself a "monopolar" pm, simply by sticking a bunch of pms to a steel sphere, all facing north to the sphere.

A black hole is a good example, because it clearly has that direction. Otherwise it would't suck in stuff. The center may be of high density, nevertheless it's a destination.
