Floating on Air
A maglev train is kept floating above the guide rails with a very stong magnetic field. The train is actually separated by 10 mm of air between the train and the guide rails. Hence, there is only air resistance. On a maglev train, there are no wheels. Instead, there are magnets charge as those on the train. For example, a positivety charged megnet will push away from another positively charged megnet. Likewise, a negatively charged magnet. This is because the electrical charges in both magnets are opposing each other. This helps lift the train off the guide rail and pull it forward.
