Levitation (physics) in the context of "Magnetic levitation"

Air hockey is a tabletop sport where two opposing players try to score goals against each other on a low-friction table using two hand-held discs (mallets/pushers) and a lightweight plastic puck.

The air hockey table has raised edges that allow the puck to reflect off horizontally, and a very smooth, slippery surface that further reduces friction by suspending the puck on a thin cushion of air ejected from tiny vent holes built inside the surface. This causes the puck to hover and move easily across the table with little loss of velocity, which simulates the lubricated sliding of an ice hockey puck across a well polished rink, hence the name of the game.
