Superconductor Flux pinning/Meissner effect with electromagnets?

Click For Summary
The discussion centers on the Meissner effect in high-temperature superconductors, specifically whether it applies to electromagnets as well as permanent magnets. It is noted that the mechanism generating the magnetic field does not affect the superconducting behavior. The inquiry seeks to understand if the expulsion of magnetic fields occurs similarly with electromagnets. The consensus suggests that the underlying principles are consistent regardless of the magnetic source. Insights into this topic emphasize the universality of the Meissner effect across different types of magnets.

I was reading about high temperature superconductors expelling magnetic fields (Meisner effect). I was curious if this only works with permanent magnets or is there similar effects with electromagnets. I assume since the magnetic waves would be similar there would be a similar reaction, but everything I read or experiments involve permanent Earth magnets. Any insights would be appreciated!

What mechanism that generates the magnetic field makes no difference if that is what you are asking.
 

Thread '3D rendering of electric field lines of a swiftly moving charge'

Happy holidays folks. So I spent some time over the Thanksgiving holidays and developed a program that renders electric field lines of swiftly moving charges according to the Liénard–Wiechert formula. The program generates static images based on the given trajectory of a charge (or multiple), and the images were compiled into a video that shows the animated field lines for harmonic movement and circular movement of a charge (or two charges). Video: The source code is available here...
