What is the Mystery of the Magnetic Paradox?

Homework Statement

Does anybody have any idea about magnetic paradox.i saw a university question where they asked to write a short note on it.i searched google , griffiths, jackson , feynman.all my search has gone in vain.i am doing bsc hons in physics and in my 2nd year course of studies.

Google->"magnetic paradox" gives me http://io9.com/5902884/see-a-magnetic-paradox-in-action as first hit, and explanations of the effect in other hits.

Has it got anything to do with relativity? I was going through a random post .it says something about magnetic force paradox.there f=qvb is different in different frame of reference.are there any other paradoxes? Relativity is in my 3rd yr course.so i am yet to properly begin it.

When I did a google search, 'magnetic paradox' did not come up with much. Do you remember what the university question was about? There was one link I found, to the Faraday paradox, which I have heard before, and there are a few similar variants. Maybe that is what they were talking about?

They simply asked to write a short note on it.it carried 8 marks.the examination was held on UG level magnetostatics , electromagnetism, ac and transient respose of circuits, thermoelectricity, ac networks.

hmm. So pretty much the only information is that the subject is: 'magnetic paradox' ? Well, from this I would guess that they mean the Faraday paradox, but I am in no way certain.

Edit: or maybe they just want the student to think of any situation (related to magnetism) in which there appears to be a paradox, and then to explain why there is no paradox... Like a kind of free-style question... But this seems unlikely.
