The Japanese Maglev train is faster than ever before. On a test track in Yamanashi, the train has succeeded with a speed of over 600 kilometers per hour. With this "magnetog" try to create a model that shows how propulsion can be created by a magnetic field.
The progress is made by the magnets at the ends of a battery inducing a current created by the battery "short-circuited" by contact with a coil (coil) of copper wire. This current induces a magnetic field inside the copper coil. Because the magnets at the ends of the battery have the same pole orientation, "two opposite magnetic fields" are created. Hereby, the induced magnetic field pushes each other and movement is achieved. The direction of movement of the battery is thus changed by turning both magnets simultaneously (or turning the battery with the magnets 180 degrees).
The length of the copper coil is 1.0 m.
