Skin Effect
(OP)
Who can explain clearly why skin effect exist? Does it exist less at dc current or none exist? Why there is more skin effect at ac current?
If there was no electricity there would be no internet. Good point, don´t you? :D

We can see it does not apply to dc because inductance does not affect dc circuits.

This effect increases with frequency, increases with conductivity of the material, and increases with magnetic permeability of the material.

RE: Skin Effect
Skin effect generally accounts for the change in current distribution in a given conductor due to the flux field set up by that conductor (not other conductors). Conductors can influence the current distribution in adjacent conductors.... that is a similar phenomenon, but goes by another name: "proximity effect"

"Throughout space there is energy. Is this energy static or kinetic! If static our hopes are in vain; if kinetic — and this we know it is, for certain — then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature". – Nikola Tesla

Why do you think temperature has such a big effect?

These days aluminum pipe is often used for substation conductors for heavy currents. The pipe is frequently made to Iron Pipe Sizes (aluminum IPS or copper IPS).

I am not trying to go O/T here, but does this lend any credibility to high end audio speaker cable manufacturers that sell flat speaker "wire"? Personally, I have never been able to tell a difference audibly and I think my friend wasted his $$$.

RE: Skin Effect
If you want a detailed mathematical analysis of skin effect and high frequency magnetic design then the book 'Soft Ferrites' by Edgar Snelling is worth finding. Old and out of print, but an excellent reference by any yardstick.

Good engineers spent efforts once to understand this and will be capable to apply this later in analysis and - even more usefull- in synthesis of their systems.
