Undergrad How Fast Can a Magnet Train Go in a Circular Tunnel?

[leoliu88889]

I was wondering, if the magnet train is propelled by putting same polar magnet face each other at an angle and its natural magnetic property same pole repel, that's how it'spushing the train faster and faster...now what if we create a circular tunnel and have the train push itself and repel continuously faster and faster, wonder how fast it will go...

Newton's third law will prevent it moving at all.

If some setup of your train or tunnel used electromagnets, instead of permanent magnets, then all you have done is create a very inefficiently-designed electric train.

If you propose to use permanent magnets for the whole thing, it will not work at all. You can't use permanent magnets as a source of energy.
