What helps maglev trains go very fast?

Correct Answer: magnets
gravity
rollers
wheels

Explanation: The futuristic-looking train in Figure below is called a maglev train. The word "maglev" stands for "magnetic levitation. " Magnets push the train upward so it hovers, or levitates, above the track without actually touching it. This eliminates most of the friction acting against the train when it moves. Other magnets pull the train forward along the track. Because of these magnets, the train can go very fast. It can fly over the countryside at speeds up to 480 kilometers (300 miles) per hour! What are magnets and how do they exert such force? In this lesson, you’ll find out.
