The Sci Guys: Science at Home - Simplest Electric Train Experiment - Magneto-Electric Train
Welcome to science at home episode nine, season three. In this episode we will be building the simplest electric train. The simplest electric train is another type of homopolar motor and it can also be called a magneto-electric train. The simplest electric train works by harnessing the magnetic field generated when a current passes through a coiled copper wire, to push and pull magnets on the train. This train is homopolar because its polarity is constant as it functions. By the end of this video you will be able to describe why the train moves, how magnetic forces can be used to do work and how to build the simplest electric train also known as a homopolar motor or magneto-electric train.
