Does using a narrow hollow-metal-cylinder as a conductor,  multiply the power ?

An obvious question, but no one seems to have answered it .

  The electromagnetic-field rotates around a conducting wire,  so,   if using a using a narrow hollow-metal-cylinder as a conductor,  inside the hollow-metal-cylinder the electromagnetic-field would also be rotating,  and the result would be either -

      - The electromagnetic-field  rotating inside the hollow-metal-cylinder would push against itself causing friction / resistance etc,  resulting in less current being able to flow,  therefore the narrow hollow-metal-cylinder would act a as a resistor .

      - The electromagnetic-field  rotating inside the hollow-metal-cylinder would push against itself causing the field to be pushed back into the metal of the cylinder and generating excess / additional current .

Not sure what is meant by multiply power. Do you mean increase it's current carrying ability? The main reason that hollow conductors are used Is due to skin effect. Since the current flows in the outer part of the conductor there's no need for it be solid. This can  translate into considerable savings in weight and expense.
Not sure about the magnetic field question. From what I've researched the magnetic field inside a hollow conductor is zero. Try searching " circular magnetic fields - ndt resource center". Hope this helps.

- By multiplying power,  I mean getting more energy out of the cylinder, than you put in,  overunity.

- The first diagram for the skin effect on https://en.wikipedia.org/wiki/Skin_effect,  and it's description,  indicates the current flows in the outermost layers of the conductor,   so,  if the cylinder is made of very thin metal and narrow,  then maybe this concept has some validity .

-   Also,  what about coating the outer surface of the cylinder with a diamagnetic-? or dielectric-? coating,  to try and force the current to travel on the layer/surface inside of the cylinder,  to induce the effect .

Good idea .  When I initially thought of this idea ( after many other people I assume ),  I thought that if it worked as I described it in the first post on this thread,   that another way of collecting the surpass energy would be to run a wire through the center of the cylinder,  I should have posted it, however,  your idea may have a better chance of functioning .

Permanent-Magnet-hollow-cylinder
You could run a wire through a  hollow-Permanent-Magnet-cylinder ( a permanent-magnet in the shape of a hollow cylinder ), to repel the current and make it flow inside the cylinder.  that may be an easier and more guaranteed way to test the concept .

Or, you could place the  hollow-metal-cylinder inside a a conducting-coil in order to repel the current and make it flow inside the cylinder,  to test the concept .

EDIT -  Surely this must be related to metamaterials, maybe consider testing carbon or materials made of lattices/honeycombs or whatever, I assume it is not related to crystals and their claimed power amplification if you run current through them, that effect seems definitely due to the same alignment of their atoms/molecules .

EDIT - Also, consider wrapping an   Insulation-Coated-Thin-Sheet-Of-Metal  into itself to from a spiral, that would be interesting,  a cylinder/tube version of a spiral,  or,   maybe even a  Bifilar or Multifilar version.

You need to figure out what makes your ideas unique. Think of something that might closely resemble one of your ideas. Let's start with your current carrying coil of  wire inside or outside of a hollow magnetic or metal tube. Can you think of any device we have today like that? If so, in which ways are they different?
