As featured on the Nov. 9 2011episode of the Colbert Report!
From the Low Temperature Lab: A flux-pinning enhanced superconducting puck levitates above and is pinned to a magnetic figure-8 track. This demonstrates the quantum physical effect of superconductivity and the Meissner Effect as well as magnetic flux pinning. The puck is accelerated using the motors from a toy car track set.

  • how much did this cost?

  • @9144386 The costs are listed in our paper, linked in the description. The only problem is the cheap superconductors we used are no longer accessible.

  • @IthacaCollegePhysics Please don't be so cryptic, what happened to the cheap superconductors?

  • @skdkskdk The company stopped making them; I don't know why. The only place I can find now is a place in Germany that sells them for about $700 each.

  • @IthacaCollegePhysics

    And can You tell me how much did it cost before 'some place in Germany' sell it for $700 now ?

  • @DeadlyRudy The costs are all in the paper linked in the description. We bought our superconductor for $125 from SCI Engineered Materials.  The company in Germany that makes them now is called Evico.

  • NOOOOOO

  • make one with part of the track upside down!

  • Haha

    NOOOOOO! Lol

  • Kill the oil industri!.. magnetic:)

  • take away the motor and try to figure out how to make it not loose energy between the joints, or can you have one long magnet with no joints

  • hotwheels

  • LOL 1:07

  • MOM! I want a Superconducting Magnetic train for christmas!

  • WipeOut

  • a smarter thing to say is its a cool floating magnet.
