same principle as induction motor,rotor chases the rotating magnetic field.
Popularly called MegLev there are two different modes of operation. When the train is still at the station it can be held by magnets. In motion electromagnets are like an electric motor that has been flattened out. The stator on the ground ( the tracks ) and the rotor being the train. The train is confined with magnets and electromagnets. The linear motor can be in the train, "the tracks" or both. Preferable would be a combination with the tracks pushing and levitating the train along with permanent magnets. The train with balancing magnets and electromagnets to keep it in the track and going. There is a way of putting the magnets together with their fields at right angles to each other. This puts the magnetic force on one side.
You still need forces, magnetism is used in the levitating train set up
The principle that Bullet Train work on is Magnetic levitation and magnetic suspension. . .
The wheels on a train are not magnetic. They are steel wheels and the use of steel helps to reduce friction and propel the train forward.
Electrical energy in the form of electric current passing in the vicinity of magnetic field would create a mechanical rotation in the coil. So conversion of electrical into magnetic energy. Magnetic interaction brings out mechanical energy
maglev train works on alternating current..The electric current supplied to the coils in the guideway walls is constantly alternating to change the polarity of the magnetized coils. This change in polarity causes the magnetic field in front of the train to pull the vehicle forward, while the magnetic field behind the train adds more forward thrust.
Less (rolling) friction.
Patents for Maglev trains were issued as early as 1905, But the first person to demonstrated a prototype of a magnetic levitating railway car was Emile Bachelet, of Mount Vernon, N. Y. in 1913.
Train tracks are magnetic.
no there is not a magnetic train in India
Electric currents and magnetic fields are by nature and by definition related to each other. In general, a magnetic field is created by the rotation of charge. If you imagine an electron following a circular path, a magnetic field would be created in the direction perpendicular to the plane of the circle.On the other hand, electric current is defined as the flow of charge. So, an electron flowing along a wire results in current flow. This also means that the electron following a circular path (as above) creates an electric current along that same path.If a circular flow of current results in a magnetic field perpendicular to the circle, what happens for current flow along a straight wire? Basically, we see a magnetic field which bends around the wire. Imagine exactly the reverse as before, with the magnetic field circling around the direction of current flow.This basic relationship between electric current and magnetic fields results in some interesting interactions:1. Many electromagnets work by the following principle: A coil of wire is made so that when voltage is applied the current will follow a circular path. As discussed above this circular movement of charge results in a magnetic field. In this case, you can imagine the direction of the magnetic field as the line through the center of the wire coil.2. The Hall Effect: When current is applied across a conductive slab and a magnetic field is applied perpendicular to current flow, a voltage is generated in the third perpendicular direction. This occurs due to the interaction of the magnetic field generated by the flow of current and the applied magnetic field.

Magnetic levitation trainer do not run on rails but float above them. A current passes through The electromagnets in The track & on The train. The magnetism produced lifts The train upwards.
The principle that Bullet Train work on is Magnetic levitation and magnetic suspension. . .
Using linear electric motors where the rails are the "stator" and the train cars are the "rotor" (however the move in a linear fashion instead of rotating, as in regular electric motors).
