SUMMARY

Vortices in Type II superconductors can indeed move, contrary to the common assumption that they are "frozen" due to the creation of eddy currents. This movement is facilitated by the pinning of vortices, which is a critical aspect of their behavior in solid superconductors. The discussion references visual evidence demonstrating this phenomenon, highlighting the dynamic nature of flux tubes within these materials.

PREREQUISITES
  • Understanding of Type II superconductors
  • Knowledge of vortex dynamics in superconductivity
  • Familiarity with eddy currents and their effects
  • Basic principles of flux pinning
NEXT STEPS
  • Research the mechanisms of vortex pinning in Type II superconductors
  • Explore the implications of vortex movement on superconducting applications
  • Study the role of temperature in vortex dynamics
  • Examine experimental techniques for visualizing vortices in superconductors
USEFUL FOR

Physicists, materials scientists, and engineers interested in superconductivity and its applications, particularly those focused on the behavior of vortices in Type II superconductors.

I'm used to astrophysics, where flux tubes in highly conductive materials are said to be "frozen" to such materials because such movement would create a very large amount of eddy currents. So you would think flux tubes in a solid superconductor could not move at all. But it seems that the vortices in Type II superconductors tend move and that some effort is made to pin them.

What am I missing?

They do indeed move as is seen in this video.
