Maglevs have been made both with attraction and repulsion.
When attraction is used magnets are mounted on the car below a steel beam and magnetism is increased until the car lifts. Control circuits adjust the strength of the field to keep the distance proper.
When repulsion is used, the field is different and the metal plate is aluminum or copper and the field induces an electric current which makes a magnetic field which acts against the original making it float. Again control signals maintain the distance.
Additional devices - wheels or magnets keep the car centered on the rail and catch it if loses power and drops down on the rail.

Maglev is a process by which a magnet moving over a piece of metal causes electrical currents to flow in the metal that, in turn, produce forces that push the magnet upward. If the force is large enough, the moving magnet can float (be levitated).Magnetic levitation (or maglev) is used in a new generation of trains that will have cruising speeds of up to three hundred miles per hour.

Think , if it were attraction the trains would suck to the rails and not move.
With repulsion, you create a space between the train and the rail / air / so the vehicle can travel.
But once again, Wiki probably does it better

electromagnetic wave propulsion from the action of polarity repulsion of two similarly charged poles ,underneath the train are powerful electromagnets and its sitting on a magnetic field on the tracks which are also electromagnetically charged with the same polarity

I only have a basic understanding. You may want to ask a German since they are the ones developing them.

by "maglev" you problably mean the trains. they work by repulsion. check out this website. http://www.oz.net/~coilgun/home.htm for attraction.
for trains: http://science.howstuffworks.com/maglev-train.htm
