Hey guys, you know the way that say for example a magnet could attract a metallic object to itself. Say for the purpose of this question, a magnet attracts a nail to itself in a vertical plane and thus defying gravity. As work needs to be done and energy transferred to do this, where does this energy come from? I mean its from the magnet but how does this energy get lost from the magnet and how is this energy loss manifested, as in what effect does this energy loss have on the magnet?
Thanks guys!
