You might have to give us a few more clues, 11year old's school science project, final year engineering project, PhD, industrial company? Your level of knowldege, your budget, timescale?
But start here - http://en.wikipedia.org/wiki/Magnetic_levitation

yea ur right sorry,well its more of a final year engineering project,except its my first year at uni and i study physic...bout the timescal...unlimited...budget...unlimited too

thnx

Our engineering dept always had a cool demo of a bar made of (I think) alternate rings of steel and copper hanging inside some coils, then made to shoot forward through a block of wood. You just need to vary the field strenght/direction in the coils in the right order. You can do something similair to float a metal plate on coils and move it backward and forward.

I think it's called a Gauss gun - I might have a go at building this unpowered version http://scitoys.com/scitoys/scitoys/magnets/gauss.html
