2. MAGNETIC LEVITATION 3. DIFFERENTWAYSTO MAGNETICALLY LEVITATE AN OBJECT Mechanically constraint Diamagnetic levitation Superconductors Rotational stabilization Servo stabilization 4. MECHANICALLY CONSTRAINT Also known as pseudo Levitation. Two magnets are mechanically constrained along a single vertical axis, this will act to levitate one of the magnets above the other. 5. DIAMAGNETIC LEVITATION Diamagnetic materials repel a magnetic field. Less than ZERO magnetic permeability. By surrounding a diamagnetic material with a magnetic field, it can be held in a stationary position. 6. SUPERCONDUCTORS Superconductivity is a phenomenon of exactly zero electrical resistance and expulsion of magnetic fields. Superconductors works on the principle of Meissner effect. MEISSNER EFFECT 7. APPLICATION Maglev MAGNETIC LEVITATION Maglev, or magnetic levitation, is a system of transportation that suspends, guides and propels vehicles, predominantly trains, using magnet. ELECTROMAGNETIC SUSPENSION AND ELECTRODYNAMIC SUSPENSION 8. APPLICATION ELECTROMAGNETIC SUSPENSION ELECTRODYNAMIC SUSPENSION 9. APPLICATION Magnetic bearings Industrial equipment such as pumps, generators, motors use levitation to support moving machinery without physical contact. 10. APPLICATION Levitation melting Levitation melting works on the principle of Induction heating. INDUCTION HEATING 11. APPLICATION Maglev elevator Maglev elevator works on the principle of EDS (Electrodynamic suspension). ELECTRODYNAMIC SUSPENSION (EDS) 12. CONCLUSION
