What is Maglev?

 “Maglev”

= magnetic levitation.  Old concept/New technology  Maglev vs. Steel wheel and rail

Technology 

3 main functions   

Levitation or suspension Propulsion Guidance



Electromagnetic vs. Electrodynamic



Superconductors

Environmental Impact  EIS  Noise  Electro-magnetic

fields (chart in Gauss (G) units)  Benefits

Problem Statement  How

would one plan and time a transit route, while calculating power used?

Simulations • Matlab • Transportation Routes • Timing/Scheduling • Power Usage

• Track design simulations • Physics equations
