How do bullet trains float?

Bullet trains are where maglev (Magnetic Levitation) is used to propel the train down to the track. The train runs on special magnetic tracks that are designed with minimal amount of turns to prevent accidents. They are one of the most environmentally-friendly ways to travel. They have lessened the amount of car usage, therefore unclogging traffic jams. Bullet trains can also attain extremely high speed without using any friction. Friction is a force between two surfaces sliding across each other. Maglevs levitate by using magnetic levitation. Magnets at the bottom of the train are faced to repel similar poles of the track. This pushes the train up in a hovering position.
