From the Ted Talk by Boaz Almog: The levitating superconductor

Unscramble the Blue Letters


Now, now that we understand that this so-called levitation is actually locking, Yeah, we unrsdnaetd that. You won't be surprised to hear that if I take this circular magnet, in which the magnetic field is the same all around, the superconductor will be able to freely rttoae around the axis of the magnet. Why? Because as long as it raeotts, the locking is maintained. You see? I can adjust and I can rotate the sncpeutdrouocr. We have frictionless mitoon. It is still levitating, but can move freely all around.

So, we have quantum lncokig and we can levitate it on top of this magnet. But how many fluxons, how many magnetic strands are there in a single disk like this? Well, we can calculate it, and it turns out, quite a lot. One hundred billion strands of magnetic field inside this three-inch disk.

You won't be surprised to hear that if I take this circular magnet, in which the magnetic field is the same all around, the superconductor will be able to freely rotate around the axis of the magnet. Why? Because as long as it rotates, the locking is maintained. You see? I can adjust and I can rotate the superconductor. We have frictionless motion. It is still levitating, but can move freely all around.
