Magnetic levitation
Videos
Magnetic levitation or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational
Electromagnetic levitation device that includes a permanent magnet for primary force (big dark-gray ring), and electromagnets for stabilization (copper coils in the center)
Magnetic levitation can be stabilised using different techniques; here rotation (spin) is used

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of copper wire wound into a coil. A current through the wire creates
