Magnetic Fields <-- Electric Currents vs Magnetostatics

I've find this. But I I haven't look at it enough to give an opinion on it yet.

JL: I agree with the EU concept that z or theta or Bennett pinches on a large scale (!) create stars,even galaxies, but I am not so sure that the pinch conditions remain. Is there any observable evidence that our sun is still in the grip of a z-pinch of two filaments, or are we perhaps centered more or less in one Birkeland current and simply maintained by the galactic electron drift through our position in space, in this arm? I ask this in complete ignorance of how we would find out such a condition. I have also wondered if the Milky Way has polar jets, while we're at this, and why astronomical images, at any wavelength, haven't revealed jets if they are there. If they do reveal jets, post a link, please! (No NASA or ESA "artist's impressions" !)

Perhaps the amount of activity of the currents is responsible in part for the expression of the 'pinch' that we can detect. An active galactic centre displays it's shape more dramatically than a centre at 'rest'. So it might be possible that we don't find active jets as with AGC's but perhaps there is the possibility to find them in a 'dark mode' or remnants of some sorts.
Maybe you where looking for something like this ?:

A letter to Nature provides supporting evidence for that model in the form of the infrared “double helix” nebula. The nebula is located about 100 parsecs from the Galactic Center. Its axis is oriented perpendicular to the Galactic plane and is apparently connected to the circum-nuclear disk (CND), which is conventionally thought to be an accretion disk harboring a “supermassive” black hole.

The double helix is the characteristic form of a Birkeland current filament. Like the filaments in the Galactic Center Radio Arc in the first image, it is a glowing section of the electric circuit connecting the central plasmoid to the galaxy and beyond. The CND is typical of a dusty plasma ring current circulating around a magnetized celestial object. There is no gravitational or dynamical explanation for the twin helical filaments. It has no place in black hole theory. The metaphors and language used in the scientific report are wrong and misleading. The title of the report alone highlights the problem—“A magnetic torsional wave near the Galactic Centre traced by a ‘double helix’ nebula.” As usual, there is no explanation for the presence of the magnetic field (which requires an electric current and circuit) or the source of the imagined “torsional wave.” The authors admit, “The absence of a negative-latitude counterpart is another potential weakness of the torsional wave hypothesis, inasmuch as such waves should propagate equally in both directions away from the driving disk, if that disk is symmetric about its midplane” and “One question that our hypothesis leaves unanswered is why the helical structure has two strands.”

Researchers also report that “the magnetic field in the central few hundred parsecs of the Milky Way has a dipolar geometry and is substantially stronger than elsewhere in the Galaxy.” Birkeland filaments align with the ambient magnetic field which is, in turn, generated by electric currents flowing into the central plasmoid.

The energy of the jets seen issuing from active galactic nuclei (AGNs) is attributed to conversion of gravitational energy of accreting matter into radiation. But that does not explain the character of the jets, or the puzzling “quietness” of our own hypothetical black hole. As recently as 26 March in Nature it was admitted “the mechanisms that trigger and suppress jet formation in [black holes] remain a mystery.” Meanwhile, the plasmoid is well known in the plasma laboratory as a high-density energy storage phenomenon that produces well-collimated jets after a time that depends upon particle collisions within the plasmoid.

"We see two intertwining strands wrapped around each other as in a DNA molecule," said Mark Morris, a UCLA professor of physics and astronomy, and lead author. "Nobody has ever seen anything like that before in the cosmic realm. Most nebulae are either spiral galaxies full of stars or formless amorphous conglomerations of dust and gas — space weather. What we see indicates a high degree of order."

A strong, large-scale magnetic field can affect the galactic orbits of molecular clouds by exerting a drag on them. It can inhibit star formation, and can guide a wind of cosmic rays away from the central region; understanding this strong magnetic field is important for understanding quasars and violent phenomena in a galactic nucleus. Morris will continue to probe the magnetic field at the galactic center in future research.

This magnetic field is strong enough to cause activity that does not occur elsewhere in the galaxy; the magnetic energy near the galactic center is capable of altering the activity of our galactic nucleus and by analogy the nuclei of many galaxies, including quasars, which are among the most luminous objects in the universe. All galaxies that have a well-concentrated galactic center may also have a strong magnetic field at their center, Morris said, but so far, ours is the only galaxy where the view is good enough to study it.

Morris has argued for many years that the magnetic field at the galactic center is extremely strong; the research published in Nature strongly supports that view.

The magnetic field at the galactic center, though 1,000 times weaker than the magnetic field on the sun, occupies such a large volume that it has vastly more energy than the magnetic field on the sun. It has the energy equivalent of 1,000 supernovae.

G'day

Z- pinch is an ongoing process that creates solar flares, spikes and axion/dilaton main flares.

I think some one wrote up on this in one of the posts.

Thanks, guys. Good comments and references. I think there should be a distinction between a jet (highly collimated; very high velocity, etc, found with AGN, and perhaps the 'normal' polar discharge which would be Birkeland currents completing the circuit up out of the center and back out and down to the rim at the arm terminations (in the case of a spiral galaxy, anyway). The first would be much more violent than the latter, and is not a candidate for our galaxy, from the evidence, even the spiral nebula, Stefan, which is an intriguing visual, although not well centered. That this current may be operating in glow mode or less is also an interesting lead for thought.

Excellent find.
I will make a seperate thread for this in the Science section.
Cheers

The excellent thoughts on Polar Jets from the Galactic Core are a constant mental stimulus of pictures of two probe pump beams that drive the original Faraday Disc of the Galactic Center which sends a powerful beam out to the stars and the phase conjugate from the stars is emitted back to the GC, which all then repeats itself due to the holographic grating field created from this arrangment we see in all universal forms. This four wave mixer scheme, from non linear optics research, is easily applied to what we see all the time from galaxies to sight. The structure of two longitudinal forms at the equator creating a phase conjugate standing wave transmission of energy non local in time, and two polar jets emitting (the probe "pump" beams) to keep the non linear event going.
