A brief review of magnets will help explain how maglev (magnetic levitation) trains work. Every magnet has a north pole and a south pole. Similar poles of two magnets repel each other; opposite poles attract each other. These principles govern the levitation of maglev trains. Permanent magnets are always magnetic. read more

Once the train is levitated, power is supplied to the coils within the guideway walls to create a unique system of magnetic fields that pull and push the train along the guideway. The electric current supplied to the coils in the guideway walls is constantly alternating to change the polarity of the magnetized coils. read more
