Solution

The correct option is B Eddy current
It works the same as a disk eddy current brake, by inducing closed loops of eddy current in the conductive rail, which generate counter magnetic fields which oppose the motion of the train.

Q. Advanced countries are making use of powerful electromagnets to move trains at high speed. These trains are called maglev trains (abbreviated from magnetic levitation). These trains float on a guideway and do not run on steel rail tracks.
Instead of using a engine based on fossil fuels, they make use of magnetic field forces. The magnetized coils are arranged in the guide way which repels the strong magnets placed in the train's under carriage. This helps train move over the guieway, a technic called electro-dynamic suspension. When current passes in the coils of guieway, a typical magnetic field is set up between the undercarriage of train and guideway which pushes and pull the train along the guideway depending on the requirement.
The lack of friction and its aerodynamic style allows the train to move at very high speed. The levitation of the train is due to
