Because of Meissner effectthe Meissner effect, magnetic fields can only infiltrate superconductors as discrete flux tubes. 

Normally, a flux tube has two ends where magnetic fields enter and exit the superconductor, but what if the flux tube is circular with nowithout any open ends? Would such circular tubes collapse and disappear inside the superconductor? What

What if there are two circular tubes interlocked to each other?

Could there be a circular flux tube in superconductors?
