The London penetration depth which arises from the relation of the curl of the density to the magnetic field gives an exact description of this effect. In a mixed-state version of this effect, the magnetic field is constrained within filaments in the material, if it is a type II superconductor. By combining the London equation with Maxwell's equation, it is found that the value for B, the magnetic field inside the superconductor, must be identically zero unless the penetration depth is infinite.

FTP, identify this effect where the magnetic field disappears as a material becomes a superconductor.
