My apologies for posting something that I'm sure people will say has been answered before, but a trawl through the results of a search of magnets didn't come up with a satisfactory answer.
If I hold a permanent magnet a few centimeters over my desk and slowly move it across a paperclip the paper clip will jump up to the magnet thus gaining potential energy, where does that energy come from?
