Never mind the title. It could be New York City to Newark. The idea is thus: Permanent Magnet Rail - Train Now imagine a train running on rails, and permanent magnets arranged on the side of the train, suitably arranged so as to cause forward motion of the train? I am not familiar with calculations involving magnetic forces, so maybe the cost of such an arrangement would be prohibitive given the cost of 'rare - earth' permanent magnets, and how many would be needed. And what about the effect of magnetic forces on passengers? Another Method- Suspended slightly off kilter magnetic suspension In fact, a method of suspending a train using permanent magnets only has been devised: http://www.21stcenturysciencetech.com/articles/magnetrain.html If the arrangement of magnets were slightly out of true, would it not result in a small force in either direction to push the train along?
