When a magnet pulls a paperclip, what exactly is doing work on the paperclip? It cannot be a magnetic force can it? I thought it was a very strong statement that I read in my intro physics book and even Griffiths(pg. 207) that magnetic forces do no work. So what is responsible for accelerating a paperclip towards a magnet? Is it something related to the changing magnetic flux? Is there an electric field somewhere doing the work? Thanks.
