Some superconductor help

  1. Feb 9, 2012 #1
    Hello!

    Me and some friends are doing a phyics project at school. The theme is superconductor. The school have a superconductor, but its broken i half (like two half moons). My question is: will this effect the result? And does the thickness matter how far above the surfice it will levitate?

    And does anyone have any suggestions were you can buy superconductor (cheap)?

    This is what we though about.



    Thank =)

    No, it won't look as pretty but it won't affect the main results

    No, not at the scales we are talking about here. As far as I remember there are some pre-factors that come into if the SC is very thin or very narro, but the length scale is set by the penetraton depth whihc is of the order of tens of nm, meaning this is not an issue here.

    Okay, we had some problems with our superconductor, it only levitated max 0.1-0.5 mm above our magnetics. Can we improve it in anyway?

    What was the strength of your magnets?

    Hmmm. Would stronger magnets have any effect?

    We got really strong magnetics. We suspect that we might need a stronger superconductor
