Default Contrary current flow within a radiator

This question may have been asked before, but is there a physical
experiment that is good for verifying skin effect?

Initially, It seemed pretty straightforward, but giving some thought to
the matter indicates it "ain't necessarily so".

I'm assuming that any thick conductor is going to have "skin" to any
where I can put a sensor, so even if I drilled an internal sensor, the
drill tunnel would form a part of the skin.

Giving that some thought, is it possible to make say a ribbed conductor
that resembled a tubular heat sink, would this device allow for more
current flow because of the greater amount of skin exposed compared to a
solid tube?

Just a little thought experiment.

Mike;

The short answer is "YES". It's called a "Faraday Cage"....
