Abstract
Magnetic levitation systems are receiving increasing attention recently, due to their practical importance in many engineering systems. There are different applications of magnetic levitation in industry such as levitation of models in a wind tunnel, vibration isolation of sensitive machinery, levitation of molten metal in induction furnaces, levitation of metal slabs during manufacture, bio-medical instrumentation, mechatronics, etc. The suspension of objects in air with no visible means of support due to magnetic force is called magnetic levitation. The development of magnetic materials and magnet design has combined with the development of solid-state electronic devices and their ever increasing current carrying and switching capacity to produce controlled magnetic levitation systems capable of supporting heavy payloads. Magnetic levitation is produced in many different ways.
