Think About Water...
One way to visualize the action of an inductor is to imagine a narrow channel with water flowing through it, and a heavy water wheel that has its paddles dipping into the channel. Imagine that the water in the channel is not flowing initially.
Now you try to start the water flowing. The paddle wheel will tend to prevent the water from flowing until it has come up to speed with the water. If you then try to stop the flow of water in the channel, the spinning water wheel will try to keep the water moving until its speed of rotation slows back down to the speed of the water. An inductor is doing the same thing with the flow of electrons in a wire -- an inductor resists a change in the flow of electrons.
Explanation of inductance needed
I need a simple, yet comprehensive explanation of how basic inductance works.
I'm going to drift from carbonzit's request slightly too.It seems we all have our favorite & despised analogies. I don't particularly like the water one, but if it helps the visualization... all good.
OK, I'm going to try to focus like a laser beam on the one aspect of inductance that I really want to understand. I think it's clearer to me now, since I sat down and drew some pictures (see below). For me, that always seems to help.
The one aspect I was having trouble with was this: the effect that a changing voltage has on a coil.
As we all know, when a changing voltage is impressed on an inductor, either increasing or decreasing, the inductor acts to oppose that change (hence the analogy to "inertia").

While the explanations in your last post appear to be true, taken as a whole,
they appear to be convoluted and unnecessarily complicated. I think you should look at how both coils and capacitors work from an energy point of view.
If you apply a voltage across a horizontal wire with plus on the right, you first get a field that is increasing, and that increasing field induces a voltage in the wire just like the battery, only in reverse.
I think you are correct.
The expanding shape of the lines of force around the conductors is responsible for the back EMF.
********
As to your next paragraph about missing a few details .....
I dont think you missed anything.
And your drawings are too good to have been drawn with a mouse.
Although they are clearly drawn by hand.
My guess is a touch screen.
This is not exactly correct, the back EMF is due to the rate of increasing magnetic flux density surrounding the inductor [conductor]The expanding shape of the lines of force around the conductors is responsible for the back EMF.
