Superconductor Flux pinning/Meissner effect with electromagnets?

[BigDogPhysics]

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.
