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.
Kuchel P, Chapman B, Bubb W, et al. Magnetic susceptibility: Solutions, emulsions, and cells. Concepts in Magnetic Resonance Part A, 2003, 18A: 56–71 Nemiroski A, Soh S, Kwok S W, et al. Tilted magnetic levitation enables measurement of the complete range of densities of materials with low magnetic permeability.
The two primary issues involved in magnetic levitation are lifting forces: providing an upward force sufficient to counteract gravity, and stability: ensuring that the system does not spontaneously slide or flip into a configuration where the lift is neutralized.
Active magnetic levitation, used in maglev transports, is not indicated for energy harvesting because it consumes power to work. This approach uses electromagnets, which implies that the thrust force increases proportionally to the velocity of the cradle.
The two main types of magnetic levitation are electromagnetic levitation and superconductor-based levitation. One form requires an active energy input to sustain levitation, while the other needs cryogenic temperatures to achieve levitation.
This is the effect seen in the LevitronTM [8,9] and the magnetic Paul trap [10,11]. The spinning rate of the Levitron is typically 500 rpm , much lower than seen in the novel type of magnetic levitation. Furthermore, since it is not a driven system, once friction with the air slows the magnet spinning rate, it loses levitation.
