Superconducting levitation and transportation

  1. Jul 24, 2007 #1
    Hey, think this post belongs in this section.

    I've seen a few videos about superconducting levitation and it is used on trains, correct?

    I was wondering if it is possible to levitate an object like a car and propel it forward?

    Heres a clip, please dont delete :) watch it please :D

    One of the properties of superconductors is that they don't allow a magnetic field to pass through them - this is what allows a small piece of supercoductor to float above a magnet.

    Even when superconductors are used in maglev trains they are used for a different reason. In the tracks are permanent magnets, in the train is a magnetic coil repelling these magnets, supercoductor magnets could be used here because it is possible to make a very large electromagnet with no loss of power due to heating. But because of the difficulty of cooling the supercoductor it may be cheaper to use a regular magnet and waste the heat.

    It's certainly possible to levitate a car using a magnet - junkyard cranes do it all the time!
