Movie when superconductivity ends

I think you have seen the image that the magnet is stopping in the air on the superconductor cooled to an extremely low temperature.

Well, it was a long doubt, will Potri suddenly fall down when low temperature is lost? Or is it just going down slowly with increasing temperature?

The answer is obvious in the movie below.

The nature that stops in this air stops is called "pinning effect". You can also check the strength of the pinning effect in the above movie.

The following sites are detailed about why the pinning effect occurs and superconductivity itself.

Superconductivity - Wikipedia

In addition, although it is about which notation is "superconductivity" and "superconductivity", it is often written as "superconductivity" in academic terms and "superconductivity" in practical genres.
