Can magnetic poles have varying strengths?

[samsanof]

I'm quite new here, but here's my question:

Is there a way to make one magnetic pole stronger than another?

There are no magnetic monopoles (at least no were found yet), so all field lines are closed. In terms of classic magnets, this corresponds to "poles of equal strength" (note that it is not trivial to define "strength of a pole" at all). You can get a different field strength, but that has to correspond with a different size of that field, too.
