What else can I help you with?
What kind of friction that maglev train still has to overcome?
Air resistance.
Where is their friction on a maglev train?
Friction on a maglev train primarily occurs at the contact point between the train's magnetic levitation system and the track, as well as between moving parts such as wheels and bearings. Additionally, air resistance can also create some friction as the train moves through the air at high speeds.
How the maglev train help to reduce friction?
It floats, thus no physical contact ... except with air.
Why does a maglev train only nees to overcome friction from the air as it travels?

What is the diffirence maglev train and the hovercraft?
A "maglev" or "magnetic levitation" train is suspended over the magnetically polarized rail. A hovercraft is more like a low-flying helicopter, using fans to blow air down underneath the vehicle. A hovercraft is sometimes known as a "ground effect vehicle", because it compresses air between the ground and the hovercraft. Hovercraft do not require tracks, and are equally able to "fly" over land and water.
Why can a maglev train not go as fast as a plane?
Maglev trains have speed limitations due to air resistance, power consumption, and safety concerns at high speeds. Planes have higher top speeds because they operate in thin air at high altitudes, allowing them to overcome air resistance more efficiently. Additionally, planes are not constrained by friction with tracks like maglev trains are.
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.
How can a train float in the air?
It is possible because a Chinese train MAGLEV floats above a magnet. How does it do it : it takes a bunch of safety precautions but they made it North and North so the magnets repel each other. For more information email me at Trainboybertron@outlook.com
Is maglev train environment-friendly?
You can say yes, because it run on electricity and it has no friction other than air resistance, but it isn't so simple. There is constant need for energy to keep train levitating so energy consumption is not lower than high speed train and if speed is low conventional high speed train may win in energy consumption. But if you compare maglev to aircraft, maglev would definitly would win. Maglev tracks are extremly expensive, there is only one Maglev build for regular passengers, between airport and city center in Shanghai. There is doubt if it could be economical to operate and even maglevs aren´t much faster than conventional high speed trains. France TGV record is 571 km/h, but japanese Maglev record is only 581 km/h and this isn't big difference.
Is hovercraft and a maglev train similar?
They are similar only in that they both aim to reduce the friction that come from the vehicle moving over the water or rails. The means is quite different. The hovercraft uses a cushion of air and the maglev uses the repulsive force of a magnetic field.
What is the coolest thing about maglev trains?
Their air-conditioning systems.
How does a sidepull bridle help to train a horse?
it helps to keep their head from flying in the air, and it helps them go into the bridle
