Magnetic field behind superconductors

[losbellos]

Hej Guys,

Is there a way to calculate the magnetic field behind a superconductor? I mean the model is like some simple block magnet and a bigger superconductor plate to try to shield the magnetic field. How strong the magnetic field would be above(behind) the SC?

B, H is given.

Also is the force of moving out an SC plate in between two magnetic field is significant? Dependent on polarity or not?

Thank you!

Not my field really. I couldn't google exactly what you asked but perhaps as an example see..
