MAGLEV TRAINS Dylan Mc. Larty & Tristan Gaddis August 3 rd, 2012

WHAT ARE MAGLEV TRAINS? • Magnetic Levitation Trains • Experiments date back to the early 1900 s • James Powell, 1950, New York • Transrapid 05, Hamburg, Germany 1979 http: //science. howstuffworks. com/transport/en gines-equipment/maglev-train. htm

STATISTICS ON MAGLEV TRAINS • Travel at a speed of 300 mph • Electrodynamic holds the world record for highest speed • Only three public systems world-wide • Only two Major accidents • Shanghai Transrapid, August 2006 • Lathen, Germany, September 2006

MAGNETISM • The Force that causes magnets to attract or repel • Changing magnetic fields can induce Current • Electric Fields induce magnetism http: //www. magneticshield. com/faq/interference. html

ELECTRODYNAMIC SUSPENSION (EDS) • Only work as the train is moving due to eddy currents in the magnetic field. • Liquid cooled Superconductors • Interferes with electronics http: //en. wikipedia. org/wiki/File: Maglev_Propulsion. svg http: //en. wikipedia. org/wiki/Maglev#First_patent

ELECTROMAGNETIC SUSPENSION(EMS) • Supported on electromagnetic arms over a steel rail • Works at any speed • Naturally unstable http: //www. theenterprisectr. org/high-speed-ground-transportation/maglev-technology. html

ELECTRODYNAMIC VS. ELECTROMAGNETIC SUSPENSION • Electrodynamic • Requires wheel and additional track design • Naturally stable • Electromagnetic • Always floating • Naturally unstable

USE OF MAGLEV TRAINS • Pros • Lower oil dependance • Safety • Cons http: //www. randomwire. com/maglev-flig • 54 miles of rail can cost $3. 5 billion
