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 … See more Magnetic materials and systems are able to attract or repel each other with a force dependent on the magnetic field and the area of the magnets. For example, the simplest example of lift would be a simple dipole magnet positioned … See more Known uses of magnetic levitation include maglev trains, contactless melting, magnetic bearings and for product display purposes. Moreover, recently magnetic levitation has been approached … See more • Acoustic levitation • Aerodynamic levitation • Electrostatic levitation • Optical levitation See more Earnshaw's theorem proves that using only paramagnetic materials (such as ferromagnetic iron) it is impossible for a static system to stably levitate against gravity. See more For successful levitation and control of all 6 axes (degrees of freedom; 3 translational and 3 rotational) a combination of permanent … See more Legends of magnetic levitation were common in ancient and medieval times, and their spread from the Roman world to the Middle East … See more • 1839 Earnshaw's theorem showed electrostatic levitation cannot be stable; later theorem was extended to magnetostatic levitation by others • 1913 Emile Bachelet awarded a patent in March 1912 for his "levitating transmitting apparatus" (patent … See more WebNotably, the passive magnetic levitation concept is a core feature of proposed hyperloop transportation systems, which is essentially an Inductrack-style train that blasts through a sealed tube that encases the …
