thats pretty awesome. although when it comes to larger amounts of power i would be a little skeptical because neo magnets are made of ceramic, and coated in nickel. and only the nickel coating is conductive, not the magnet itself. but being such a small connection id think it wouldnt be too bad with small power, since the electrons dont have to travel very far, now stack 50 magnets together and do the same thing and resistance would definitely play a part. i also think about the heat created by having a current pass though the magnet, and the build up over time potentially affecting the magnetization, and the resistance the heat increase causes. i also just read that when you pass a current through a magnet, the flow of electrons in one direction, affects the poles on the magnets since they flow in both directions, and can negatively affect the magnetic bond. something to think about, seems like an awesone idea though.
