Great tutorial. I will definitely make this one for myself and post some pictures.To improve the design a little so we can prevent a short with battery polarity reversed, have the magnet with the positive end contact, a little recessed. This will allow only the protruding top (positive) end of the battery to make contact with it. When you try to touch it to the other end, the positive end of the wire contact might stick to the battery's negative end because of the magnetic pull, but will not make contact with it, preventing a short circuit.
