“Andy takes a closer look at one of his favourite demos from the 2012 Christmas Lectures, bringing together a levitating superconductor and a bewildering Möbius strip made from over 2,000 magnets.
As his super-conducting boat whizzes along the track, Andy demonstrates the remarkable properties of the superconducting material (Yttrium barium copper oxide) which allows it to seemingly float both above and below the track.” (YouTube)
Ah, superconductors. Amazing, aren’t they? The above video by the Royal Institution demonstrates and explains what is happening in a levitating superconductor, and the Möbius strip enhances this explanation.
Supercool stuff. Onwards!
