will my idea work?

Well no, if you would use magnets, if you put both north poles against each other, notice how they propel the oposite way and not against each other, a negative and positive coil would propel against one another.

But it was a nice try

yeah but place a magnet under the ground set at north upwards, then place a magnet on a stand or somein above the spot where the magnet is with negative faceing down then place a normal manet in between the magnets and the thing will hover cause it will be pulled by 2 equal forces makeing an equilibriam

That is how Maglev works I think.

yeah thats how it works sorta but its just the magnets on the ground.
