How To: Make a maglev motor

Ian uses round magnets, pencil, clay and glass slide to work his magic science experiment. Magentic levitation is said to be a solution for energy costs of trains because it cuts down friction and creates what is mythically regarded as a perpetual energy motor. This is an interesting toy model of how the maglev trains and large scale generators work
