Permanent magnet trapped inside a superconductor

Click For Summary
SUMMARY

The discussion centers on the behavior of a permanent magnet when placed inside a superconductor, particularly when the superconductor is cooled to its superconducting state. It is established that the superconductor would confine the magnetic field generated by the permanent magnet, potentially creating a condensed magnetic field within the superconductor. The conversation also highlights the role of Type-II superconductors, which may allow for some flux penetration, provided the magnetic field strength does not disrupt the superconducting state.

PREREQUISITES

I was wondering what it would be like if you had a permanent magnet inside the core of a material capable of obtaining the superconducting state. And you cooled it down so that it becomes a superconductor.

Assuming it didn't explode; would it just condense the magnetic field into some contained ball? What about the portion of the field outside of the superconductor? Would that get squelched off? Where would it go?

The superconductor would compensate the magnetic field from the permanent magnet and therefore confine the field to the interior of it, maybe with some flux penetration in Type-II superconductors.
This assumes that the field is not strong enough to break the superconducting state.
