Electromagnetic suspension is the magnetic levitation of an object achieved by constantly altering the strength of a magnetic field produced by electromagnets using a feedback loop. In most cases the
Floating globe. Magnetic levitation with a feedback loop.
The Transrapid system uses servomechanisms to pull the train up from underneath the track and maintains a constant gap while traveling at high speed
Maglev is a system of rail transport whose rolling stock is levitated by magnets rather than rolled on wheels.

…friction. It also avoids wear and has very low maintenance requirements. The application of magnetic levitation is most commonly known for its role in maglev trains. Samuel Earnshaw was the one to discover in 1839 that “a charged body placed in an electrostatic field cannot levitate at stable equilibrium…
