Levitation (on Earth or any planetoid) requires an upward force that cancels out the weight of the object, so that the object does not fall (accelerate downward) or rise (accelerate upward). For positional stability, any small displacement of the levitating object must result in a small change in force in the opposite direction.
Magnetic levitation can be stabilised using different techniques; here rotation (spin) is used. Magnetic levitation (maglev) 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 force and any other forces. [2]
The applications of photophoresis expand into the various divisions of science, thus physics, chemistry as well as in biology. Photophoresis is applied in particle trapping and levitation, [3] in the field flow fractionation of particles, [4] in the determination of thermal conductivity and temperature of microscopic grains [5] and also in the transport of soot particles in the atmosphere.

Levitation is the process by which an object is held aloft, without mechanical support, in a stable position. This category is for articles directly related to the physics and science of physical (non- illusionary ) levitation (i.e.: magnetic levitation ).
Electromagnetic suspension (EMS) 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 levitation effect is mostly due to permanent magnets as they have no power dissipation, with electromagnets only used to stabilise the effect.
