A round, 3 dimensional object labeled N on top and S on bottom.
What is the best way to arrange the magnets on the train and on the track so that the model train levitates?

flat, so that the north pole of the magnets on the train point up and the north poles of the magnets on the track point down
on edge, so that the north poles of the magnets on the train point to the front and the north poles of the magnets on the track point toward the rear
on edge, so that the north pole of each magnet on the train and on the track point toward the rear of the train
