MAGNETIC LEVITATION AND TRAINS BY: MANISH KUMAR 2K12/EE/075 Delhi Technological University INTRODUCTION MAGLEV = MAGNETIC + LEVITATION Magnetic means “based on magnets” Levitation means “to rise and float in air” Maglev is a method of propulsion that uses magnetic levitation to propel vehicles with magnets rather than with wheels that the conventional trains use. Magnetic levitation is the use of magnetic fields to levitate a (usually) metallic object. Manipulating magnetic fields and

2.1 Motors use the effect of forces on current-carrying conductors in magnetic fields 2.1.1 The motor effect The motor effect is where a force acts on a current-carrying conductor in a magnetic field. The right hand palm rule is used to find certain properties: fingers point to magnetic field‚ thumb points in DC direction and palm points to direction of the force. 2.1.2 Factors affecting the force acting on the current-carrying conductor Forces are experienced by the electrons in the conductor

Electrical technology – assignment 4 Properties of electrical materials and Effective use of technology P.5. Describe the properties and a typical application of a solid and a liquid or gas electrical conductor. A conductor is a material that allows free movement of electrons and therefore allows easy flow of electricity. Most conductors are metals. A common metal used as a conductor in electrical technology is aluminium. It is used quite a lot as it cheap‚ lightweight and in abundance compared

Magnetic bearings: The lubricated bearings in ordinary systems is replaced by a digitally controlled magnetic bearing system‚ consisting of both permanent magnets and electromagnets. the compressor shaft” being the only rotating part is is levitated and held in place by magnetic bearings. Four positioning signals take the position to within 0.00005 of center.. This requires an amazing sampling rate of six million

lived from about 625 BC to about 545 BC.[1] Around the same time‚ in ancient India‚ the Indian surgeon‚ Sushruta‚ was the first to make use of the magnet for surgical purposes.[2] There is some evidence that the first use of magnetic materials for its properties predates this‚ J. B. Carlson suggests that the Olmec might have used hematite as a magnet earlier than 1000BC[3] [4] In ancient China‚ the earliest literary reference to magnetism lies in a 4th-century BC book named after its author‚ The
