Demonstration of the Meissner effect (simple YBCO superconductor)

   The Meissner effect is that a constant magnetic field is pushed out of a superconductor. Since the field inside the superconductor is zero, there must be a source of the opposite magnetic field. This source is the superconducting current. Because of the perfect diamagnetism, a magnet can levitate above a superconductor.

Levitating magnet

Demonstration of magnetic field locking and power levitation force (Domain YBCO superconductor)

   The magnetic locking occurs in a domain superconductor when it is cooled in a magnetic field. If an attempt is made to change the magnetic field, a current will be generated in the superconductor that prevents this change.

  The power of interaction between the domain superconductor and the magnet is significant. (Note: there is also simple YBCO superconductor that can be used to show the Meissner effect)

   If you try to press the magnet against the surface of the domain superconductor, you can experience the power of the repulsion force. !!!On a simple YBCO superconductor, the repulsion force is very small!!!

   By taking the domain superconductor out of liquid nitrogen towards the magnet, you can see that it is stably captured by the magnet no matter how you rotate it. !!!This effect is absent on a simple YBCO superconductor!!!
