A phenomenological magnetic-response law distinguishes Meissner screening from simple flux freezing while leaving microscopic/interface questions open.
Scientific scope
A phenomenological magnetic-response law distinguishes Meissner screening from simple flux freezing while leaving microscopic/interface questions open. The admitted result is a phenomenological magnetic-current/field relation giving screening over a material-dependent length instead of generic flux freezing. The 1935 electrostatic/covariant supplement and all proposed boundary/heat statements are historical model claims, not uniformly established modern facts. Original 76 restricts the potential representation to simply-connected bodies and defers multiply-connected extension. Sphere/infinite-wire examples assume stated geometry and interface conditions; the superconducting/normal interface radius is undetermined without an extra condition, and the minimum-heat choice is expressly a conjectural supplement. Quantum coupling/eigenstate discussion is a programme, not a solved microscopic origin. Qualitative transition-curve resemblance is not a certified measurement fit. All target 71–88 text read; Original Meissner experiment,1936 revision, later Ginzburg-Landau/BCS and applications are distinct. No universal exclusion of vortices, arbitrary fields, all materials or arbitrary topology claimed.
