Does Dielectric Displacement Current generate a magnetic field?
Reiyuki:
Here's the question for everyone:
"Does displacement current generate a magnetic field? If so, where and at what angles?"
Either answer can have some wild ramifications, so think carefully.
(I'll be updating this post with new information as the topic evolves, but I'd like to see what your own thoughts are on the matter)
Dog-One:
I'll step up to the plate. No guarantees, only a swing or two at the ball.
We mostly know what an electron does right? As far as electrical current goes.
Okay, so think for a moment. An electron has a negative electrical charge.
Now ask yourself this: Where does this charge come from that the electron
carries around with it?
???
Does it matter? Something gives it charge right?
So is there any reason this thing that gives an electron a negative charge
have to be bound to an electron? I don't think so. Charge is charge. It
can be associated with a particle of matter like an electron or a proton or
be completely on its own without any association with matter.
So charge can create current and it can be massless, or mass, or a
combination of both. Current is the key here. It's not just sitting
there. It is displacing, changing, moving. The current creates the
magnetic field. Then the current must be charge in motion. I would
say lightning is charge in motion, but does it create a magnetic field?
I think so. I do not know for sure. Not something I have played with,
but once and I lost four hours of consciousness doing it.
Your question is a good one, because with more than one type of
current, the magnetic fields created by these varieties may have
different properties, each with their own utility.
A couple years back I looked at a concept known as Tetryonics. I'm
not convinced this theory is accurate, but it did promote some
imagery that helped to understand what things might be doing.
The way in which charge moves is very likely the key to understanding
how a magnetic field forms. My hunch is the magnetic field always
works at right angles to the vector of charge motion. When the
charge is associated with a spinning mass, you can imagine the
field it creates is likely rotational in nature. The interaction of
multiple spinning masses would then produce a very complex
pattern of magnetic flux. These would line up in a way to create
minimal stress within the localized area. The rules would be
obeyed, whatever those rules truly are.
Looking forward to reading what others have to say about this
topic.
Some may want to spend some time with this one:

Thanks Dog-one and Lanca

That's a good way to explain it.
With this explanation, it would mean that charging a plate capacitor would create two opposed axial fields (twisting/spiral magnetic fields), one on each plate. One plate CW, the other plate CCW.
Those fields would disappear as charge is built and current stops flowing as the cap is charged.
@lancaIV
You see exactly where I'm going with this, eh? ;)
Lets take the above analysis where a charging/discharging cap creates a CW and CCW magnetic field, and apply it in reverse:
If we create an expanding CW field and CCW field opposed to each-other, does that mean we just synthesized a capacitor?
Dave45:
Why does an electron only create a magnetic field when its moving, why not at rest?
When its energized is it spinning and not at rest?
