Maglev

  1. 1. MAGLEV (Magnetically levitated trains) Trains that fly!!!!!!
  2. 2. MAGNETIC LEVITATION1. Process of suspending an object in air with the help of magnetic fields2. Moving a good electrical conductor like gold on a magnet produces eddy currents on the conductor3. At a sufficiently high rate of movement, a suspended magnet will levitate on the metal, or vice versa with suspended metal4. Superconductors bieng fully diamagnetic repel magnetic fields and can levitate when a sufficiently high amount of magnetic field is applied
  3. 3. The History of Magnetic Levitation Vehicles 1- 1750 – John Mitchell conducted the first experiments measuring the magnetic forces between the poles of a magnet . 2-1900 – Robert Goddard and Emile Bachelet conceive the concept of frictionless trains. 3.-1969 – American scientist James R. Powell and Gordan T. Danby patented the first design for Maglev trains. 4-1970 – German and Japanese engineers start research and development towards their versions of Maglev technology.
  4. 4.  2003 – The Shanghai Trans-rapid Maglev Line is inaugurated.
  5. 5. How maglev works 1-A maglev train floats about 10mm above the guide way on a magnetic field. 2-2 ways of levitating a train-Electromagnetic suspension(EMS) and Electrodynamic suspension(EDS). 3-Both ways have the same underlying concept-a magnet will repel another magnet.In both cases magnets in both the track and the undercarriage of the train repel each other to levitate the train.
  6. 6. EMS
  7. 7. EDS
  8. 8. Advantages 1- Because the train floats along there is no contact with the ground and therefore no need for any moving parts.Hence there are no components that would wear out. 2- The trains are virtually impossible to derail because the train is wrapped around the track. 3-The trains can attain speeds upto 500km/hr which is not economically viable for commercial railways
  9. 9. Disadvantages 1-The biggest problem is that it is much more costly than conventional track railways and governments around the world arent willing to invest so heavily in such a project. 2-Anotherproblem is that the EM waves from the tracks may affect mobiles and pacemakers of heart patients
