Magnetic levitation

OverviewLiftStabilityMethodsUsesHistorical beliefsHistorySee also

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. The two primary issues involved in magnetic levitation are lifting forces: providing an upward force sufficient to counteract gravity, and stability: ensurin…

Levitation – Wikipedia

En leviterande groda i ett magnetfält på 16 tesla (ø 32 mm). Magnetisk levitation. Levitation (från latin levare, lyfta upp), fenomen som innebär att något lyfts upp och svävar fritt i luften. [1] Uttrycket används i parapsykologi och spiritism om svävande vid seanser. [2] Förmågan att levitera har även tillskrivits vissa helgon. [3]Fenomenet är inte vetenskapligt bevisat.
