Reading this, i had the same question in mind. i know it wont be repelled off track. but with the much time i've spent playing with magnets, i've realized that it gets pretty tough keeping one magnet hovering over the other by repulsion. there is always that tendency to wanna skid off and get attached to the side.
question...is there something i'm missing?

However, i feel that a possible solution to that would be increase in surface area of both magnets. that way, it doesnt skid off to one side when on high speed. i could be wrong though.

Neat write-in bro. as always

here, you will see the levitation coils are facing each other which is found under the guardway (rail track name for the maglev). The superconducting magnet made up of these coils produces a repulsive force. Each coil repels the other. That maintains the train in the centre at all time.@pangoli, I was expecting you to ask how it turns..check the image

Wait o, who's the 'We'
