Dose this feild have inertia?
Does the magnetic attribute within a volume of space have inertia?
Yes it does.
If yes, where dose it come from?
What did I say previously? I stated that all volumes of space have spin. Spin is the fundamental concept of inertia--things in motion tend to stay in motion. The curl of spin (the magnetic field) is a derivation of spin itself. So if spin retains inertia, guess what? It's extremely likely any derivation of that particular attribute also consists or is directly related to the property of inertia.
I see it has velocity according to your post, so the qustion is, what volicity is it?
Velocity implies a distance travelled over a period of time. We can deduce an instantaneous velocity, however this is still sums or averages of very tiny slices of time.
In the case of spin, we only have a distance travelled if we assume we have some radius that would give us some circumference. What if we have no radius, then what? Where is the distance? How would we then calculate a velocity?
No, velocity is not a factor here. "V' is in reference to volume, the vector field. The volume of interest would be any place where there is spin. That's a big box and I wouldn't make too many attempts trying to think outside of it.
If you have a verry long wire, (800 feet) and you put some current through it,
Dose it produce a magnetic feild around it That has volicity and inertia?
Gotcha! You fell right into the trap. You assume this piece of wire produces a magnetic field. It does not. It alters the spin in such a way where the majority of the alteration can be seen by looking at the curl of spin.
I want you to keep in mind there are two other very important attributes within any particular volume of space. There is the spin itself, the gradient of spin and the divergence of spin. The curl of spin is what we have already touched on, making the three essential attributes, all derivations from spin.
Think of spin as infinitely long rotating threads having no radius. The entire universe jam packed with these threads going every which-where, rotating at different rates, filling all voids. A spin field. An actual subatomic fabric that permeates all the universe. These are Newman's gyroscopic particles or gyrotrons. They are not points however, instead vectors. And where these vectors intersect or collide is where the action happens--those are the points. Think of them rubbing as they rotate and collide at different angles.
If yes, if that 800 foot of wire is now coiled up, and the same amount of current is applied:
By coiling up the wire and injecting a current source (also contained within your volume of interest), you have significantly altered the dynamics within that region of space.
Can I detail every single attribute you have changed and how it changed? Probably not, but with an accurate 3D model showing what the curl of spin looks like before and after, I think you'd see enough to be convinced.
Dose the magnetic feild have the same amount of volicity and inertia, more volicity and inertia, or less volicity and inertia?
Let's just think about what we have done to the spin within that volume of interest. Before the wire, coil and energy source was placed in that space, we had a fairly homogenous distribution of spin--no real pattern to speak of, call it white noise for all practical purposes.
We place all the components in that space and still things are fairly homogenous. When we apply the current source, that's when things get altered significantly. We don't have more or less total spin, but we do now have patterns forming. The spin angles are no longer in a dormant, neutral, random position. The electrical current has forced them to a new position. What does this mean big picture wise?
It means this volume of space is actively engaging everything in the universe having spin axis vectors going through this volume of space. That's a big deal. Your coil isn't operating on an island, it's connected to the entire universe. So do you suppose the universe is just going to let this coil do whatever it wants to? Probably not. The coil is only going to be allowed to do what the universe agrees to let it do--it's part of the same fabric. And walking right in the door comes things like the speed of light, inertia, etc.
Simple qustions, they should have simple answers...
Simple enough yes, but the concepts are huge.
