Levitation is the process of making an object float in the air without any physical support. While levitation is often associated with magic and the supernatural, there are actually a number of scientific principles that can be used to levitate objects.
One of the most common methods of levitation is to use magnetic fields. Magnets can be used to create a force that pushes against an object, causing it to float in the air. This is the principle behind magnetic levitation (maglev) trains, which use powerful magnets to levitate above the tracks, reducing friction and allowing for high-speed travel.
