This week I made a simple magnetic train and raced different brands of batteries. This system, known as magnetic levitation or maglev train, has a very simple working logic. In order to test it, I prepared a track using 500 meters of copper wire and after sticking neodymium magnets to the ends of the batteries, we saw how long it took for each battery to complete the track.
