Why does a maglev train only nees to overcome friction from the air as it travels?

Why maglev train is faster than ordinary train?
Because there's no friction between the train and the track. In an 'ordinary' train, friction between the wheels and the rails takes a lot of energy to overcome before the train starts moving. In a Maglev train, the train itself actually 'floats' above the track on a 'cushion' of magnetic foirce. With no friction to slow it down, the train is capable of much higher speeds.
How does the property of a maglev train helps to decrese friction?
No two solids ever touch in a maglev.
When maglev train is lifted which force reduce?
Friction. Oonce the train is clear of the track, there is no friction to slow it down.
What is electromagnet train?
You must mean a Maglev train. A Maglev train operates on maglev (magnetic levitation). It uses electromagnets (and possibly superconductors) that repel each other to lift the train above the ground to reduce as much friction as possible.
What are the four forces of a Maglev train?
All i know is 2 Friction and gravity :) xx
How the maglev train help to reduce friction?
It floats, thus no physical contact ... except with air.
Why is the maglev train called the maglev train?
maglev is short for Magnetic Levitation.
Why the maglev train is much quieter and uses less energy?
No contact with the ground (thus less friction).
What does the magnetism do in maglev trains?
Maglev is a contraction of Magnetic Levitation. Magnets of the same polarity are used to levitate the train so that there is no friction between train and rail. Electromagnets of opposing polarity are switched on in sequence ahead of the train to pull it forward.
Where is the friction on maglev train?
If you have two magnets they each have a north and south pole. The opposite poles will attract and the same poles will repel. Maglev trains create magnet fields on the track bed and the train of the same polarity. By controlling the generating of the fields you can hold up the train and propel it forward. Since the train is not actually touching a track there is no appreciable friction except that caused by the surrounding air. In a vacuum you would have no friction.
What type of train uses magnets?
The maglev train floats over its track using an electromagnet. Maglev trains have managed speeds in excess of 370mph. A model of the maglev train uses two permanent magnets to get the model to float over the track.Describe how the magnets must be arranged to get the model Maglev Train to float.
