Question

What does a maglev train use to reduce friction?

Answer 1

Hint: Friction is the force which bears or resists the relative motion of solid surfaces and sliding against each other. Dry friction, fluid friction, lubricated friction, skin friction and internal friction are the types of friction. Unit of friction is newton and in trains the friction will be created between wheels and the track.

Complete step-by-step solution:
Maglev is a system which is related to train transportation and it is derived from magnetic levitation. Maglev which uses two sets of magnet and to push and repel the train up off the track one set of magnets are used.to move elevated train foreword another set of magnets are used by using maglev technology we can reduced the number of moving part.so the only moving part is the train and magnets which control the speed of maglev train which in turn controls the stability of train. Maglev trains are noiseless and have high speed compared to conventional trains. Acceleration and deceleration can be made much faster by maglev trains.
Maglev trains which use magnetism to reduce the friction. In the track magnets are placed which opposes the other magnetic which is placed in the bottom of maglev train due to which a repulsive force is created .This repulsion will keeps the train levitating slightly above the track .due to which the maglev train runs in the air so there will less friction between the wheels and the track.

Note: Student’s maglev system consists of five essential components and that are input power transfer, levitation, propulsion, guidance and control systems. Magnets are used to control the speed of trains. Maglev technology is the most effective technology which is widely used in train transportation and effectively reduces the friction.
