I am still waiting for you to show everyone why the kinetic energy in
electron flow causes *ZERO* voltage across resistive wire.
Why would I want to do that?

One little gem:
The electrical current has an average velocity. On average, one such
electron will collide with another electron thereby transferring some
of its kinetic energy.
What happens to the first one? Does it slow down now it's lost its
kinetic energy?
This causes a DC pulse, which traverses down the resistive wire.
(Passing lightly over what a "DC pulse" might be, and how it's related
to the electron motion)
The pulse dissipates due to electrical resistance,
So what happens to the electrons' kinetic energy? Where does it go?
which generates a voltage across the wire.
Oh? How do the electrons do that? Is the voltage proportional to the
kinetic energy, or is there some other relationship?
That is how you simplify the problem
To absurdity, in this case.

As the current increases the net magnetic field increases, thereby
increasing.
You don't say.
It's well known that a magnetic field in a certain volume of space
constitutes a certain amount of energy.
Sure. Where's it going?
