All those formulas and the theories and the generalizations (self admitted generalizations) in that wiki page on skin effect were idealized, tested, hypothesized, realized, etc (however one may wish to put it) with solidus lattice structures. Not conductive fluids.
One can make a hollow cylinder of conductive fluids and drop a magnet down that cylinder and the result will be different than if done with a copper tube. Lenz is still happening but...differently. Lenz, and everything else involving electrical formulae... as the vast majority know and expect it.... was based on the analysis of conductive solidus atomic lattice structure.
As the medium is not the same (with conductive fluids). The complexity of the mathematics shoots through the roof into the impractical and (currently) incalculable. We can make some general bits of analysis, but not much more than that, at this time.
Additionally, the page from wiki speaks not on the underlying meaning and origins of the observation of ’skin effect’. Just the practical engineering mathematics. If one wants to understand the limitations of the mathematics, then the page does exactly squat.
It’s very simple: The Map Is Not The Territory.
It is on the edge of such realities that the page from wiki can and does devolve into potential misrepresentation - as dogma. Big problem.
