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]
A brief demonstration and small explanation featuring a Levitron branded levitating top device which works based upon the phenomenon of spin-stabilized magnetic levitation. Spin-stabilized magnetic levitation is a phenomenon of magnetic levitation whereby a spinning magnet or array of magnets (typically as a top) is levitated via magnetic ...
The levitated top's stabilizing rotation undergoes natural, gradual slowing, so that the levitation phenomenon fails within four minutes unless external power is supplied to sustain rotation. To levitate the top, a plastic plate is placed on top of the magnetic base, and the top is spun on the plate at 25–50 rotations per second (1500–3000 ...
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.
A cube magnet levitating over a superconducting material (known as the Meissner effect). Levitation (from Latin levitas, lit. ' lightness ') [1] is the process by which an object is held aloft in a stable position, without mechanical support via any physical contact.
Inductrack is a passive, fail-safe electrodynamic magnetic levitation system, using only unpowered loops of wire in the track and permanent magnets (arranged into Halbach arrays) on the vehicle to achieve magnetic levitation. The track can be in one of two configurations, a "ladder track" and a "laminated track".
Earnshaw's theorem applies to classical inverse-square law forces (electric and gravitational) and also to the magnetic forces of permanent magnets, if the magnets are hard (the magnets do not vary in strength with external fields). Earnshaw's theorem forbids magnetic levitation in many common situations.
Model of the magnetic levitation train (1914) Bachelet was born in Nanterre, the son of Henri Bachelet. He immigrated to the United States in 1883 [2] and became an American citizen in 1889. [3] He died in Poughkeepsie, New York. Bachelet was granted U.S. patent 1,020,942 in 1912 for his "Levitating
