Coolest Superconductor Demo Ever!

Today's post is a link to the coolest demonstration of supercondutor levitation I've ever seen.  Demonstrations of superconductors usually levitate a small magnet over a superconductor.  Here they've levitated a fairly large superconductor over a magnet.  They also demonstrate how the superconductor isn't just levitated above the magnet but is actually "locked in space" relative to the magnet, such that you can tilt the magnet and the superconductor tilts with the magnet.  To top things off, they construct a track from a series of magnets and show how the superconductor will smoothly follow the track when pushed.  Very cool!

This all takes place at Tel-Aviv University, Israel.

Finally found it!!

This is by far the best show I've ever seen on magnetic levitation.  I saw this show years ago on Discovery Channel and have wanted to watch it again ever since.  I didn't know the name of the show, and wasn't even sure what channel I had seen it on.  I tried to search for it on youtube a week ago but without knowing the name of the show, I wasn't able to find it.  Then, a couple of days ago, accidentally stumbled across it while researching maglev.

The first half of the show is a history of magician levitation and pretty interesting in itself, but the really good stuff about magnetic levitation is in the second half of the show.

Here the program is in its entirety.  Enjoy!

Sweet inductive maglev

I've been researching maglev again lately and stumbled across this video of an aluminum plate levitating over huge coil that's operating at 800A and 900hz.

Check it out.



This guy's got a GREAT series of videos on his youtube channel.
