Electromagnetic Battery Train Visible in Collection revealing the core idea behindSend a battery racing through a coil, no motor required Drop a AAA battery into one end of a coiled length of bare copper wire, and it shoots out the other end under its own power. No switch, no motor, nothing plugged in. It looks like it shouldn't work. It does, every time. That motion comes from the same force principle behind electric motors and maglev trains. Neodymium magnets attached to each end of the battery touch the coil, completing a
