You know that scene in “Back to the Future 2” when Michael J. Fox’s character Marty McFly skates on a hover board? It’s no longer just movie magic.
Tel Aviv University scientists demonstrated quantum levitation at the Association of Science-Technology Centers annual conference held last week at the Maryland Science Center in Baltimore. The researchers from the Superconductivity Group at TAU’s Schools of Physics and Astronomy wowed conference attendees with their demonstration of superconductors locked in a magnetic field.
They showed how a disc frozen with liquid nitrogen can be made to hover over a magnet in any position. Similarly, it can “fly” over a track at any height or at any angle. It even appeared to defy gravity as it circled underneath the track.
