hi, I've working on a model of a maglev train, using small magnets aligned in two rows simulating the tracks, and some magnets under the "train", I made the train levitate, which is part of what I want to do with it, but I'm having troubles to make it run, or at least move a little forward and not just levitate in the same place. Do you how to make it move? someone told me it was just by using a complicated circuit that made the magnets change polarity in certain sequence, but that this circuit was only made in a laboratory

. So, I was wondering if there is another way to make it, maybe by making a "bit of electricity" to run throughout the magnets, but how?
please send some ideas, I'll try them out. I need to have it done for monday, that means I only have a day and something.
Thanx for taking time
