Homework Help: Super conductors

  1. Mar 24, 2010 #1
    1. The problem statement, all variables and given/known data

    folks, in my textbook it has mentioned 1)superconducting magnetic propulsion system plays a role in launching satellites without the help of rocket
    2) superconductors are used to levitate trains above the rails and the example is bullet train
    i know superconductors are materials which conduct at zero resistance and magnetic lines of flux are completely excluded from the conductor.
    but how these applications are achieved?
    please explain and help in this regard will be greatly appreciated

    2. Relevant equations



    3. The attempt at a solution
