Severns, QEX, Nov/Dec 2000, pp 20-29 does address the issue.
On page 22: "At some points within the wire, the instantaneous current is
actually flowing backwards (minus signs) due to the self-induced
eddy currents that are the underlying phenomena responsible for skin
effect."
These results were verified with Ansoft's "Maxwell" FEM software.
An excellent treatment of the math can be found at:http://www.g3ynh.info/zdocs/comps/zint.html

I read that last one Frank but I think it is aimed at computer geeks
which I am not.
Pleased to see eddy currents are the underlying phenomina responsible
for skin depth
presumably he explains how the secondary current can overcome that
which creats it.
At last we have a source for free energy
