Superconductor Flux pinning/Meissner effect with electromagnets?

AI Thread 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 'Inducing EMF Through a Coil: Understanding Flux'

Thank you for reading my post. I can understand why a change in magnetic flux through a conducting surface would induce an emf, but how does this work when inducing an emf through a coil? How does the flux through the empty space between the wires have an effect on the electrons in the wire itself? In the image below is a coil with a magnetic field going through the space between the wires but not necessarily through the wires themselves. Thank you.

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...
