Transcript
Quantum Locking, or Flux pinning, is the phenomenon where a superconductor is pinned in space above a magnet. At higher temperatures the superconductor allows magnetic flux to enter in quantized packets through points in the magnet known as flux tubes, but at extremely low temperatures these flux tubes are locked into place to conserve energy causing Quantum Locking Superconductivity Superconductivity occurs when an object is cooled to a low enough temperature to allow an electrical current to pass through it with absolutely no resistance . Another effect of superconductors is the repulsion of magnetic fields. Flux Tubes A flux tube is a generally cylindrical region of space containing a magnetic field. Flux tubes can easily be created using a superconductor’s characteristics of magnetic repulsion. By placing a superconductor over a magnet, flux tubes are created through the minute cracks in the superconductor for the magnetic flux lines to pass through. • A disk that is half a micron thick, with a diameter of three inches, can support over 70,000 times its own weight when placed over a magnetic field of 350 Oe • That same disk, if made two milimeters thick could support 1,000 kilograms, the weight of a small car. • In a superconductor three inches in diameter, there exist an estimated 100 billion flux tubes when placed over a magnetic field. • Boaz Almog Levitates a Superconductor Hoverboard
