Coronal holes

[tolenio]

Hello,

I have a question on coronal holes. I was looking at a recent image from NASA and I flashed to a UCLA image mapping of a plasma discharge magnetic field. They appear to overlay. The coronal hole aligning with the null magnetic point of the z-pinch. Am I correct in this correlation?

Hello,

Coronal "holes" tend to be regions of the surface where less (or no) coronal loop activity is taking place compared to the rest of the surface. Since it's rotating over time, and it stays relatively consistent, I'm not sure how you could associate it with a specific z-pinch or a specific magnetic point. Pretty much every single coronal loop is in the process of a "z-pinch".

FYI, Hannes Alfven called the whole concept of 'magnetic reconnection" a form of "pseudoscience" a total of 7 different times during his keynote speech at the conference where he presented his double layer paper which makes the entire reconnection concept obsolete and irrelevant in all current carrying environments. He explains the double layer kinetic energy process *without* resorting to reconnection. The mainstream now routinely uses the term "current sheet" to describe such events, and a "current sheet" is definitely a current carrying environment.

I'd say that the biggest hurdle with trying to associate coronal holes with z-pinch processes begins with the fact that there are *fewer* z-pinch processes occurring in coronal holes than occur in the areas that are outside of those holes.

Magnetic 'null points' are real however. Google images of 4, 6, 8, etc, magnet configurations.
When the the configuration of magnets is changed, then the configuration of the resultant fields
also does change, with disassociations and re-associations taking place.

The EU community really does need to move beyond the old "magnetic line Reconnection" canard,
and understand what the term "separatrix " describes.

The "disassociation and re-association taking place is between to *current channels*, not just two magnetic "lines". Alfven's double layer paper describes the physical process that is taking place *without* the need to invent new terms like "reconnection" which ignores A) the total circuit energy, and B) the particle physical *reconnection* that's *actually* taking place. In terms of topology changes, the magnetic lines are just along for the ride. The changes in the particle flow patterns are doing the real "reconnecting". The magnetic fields are *created by* the currents and they are *changed by* the changes in the current flow patterns over time.

Birkeland's experiments used *circuits* and electric fields to do all the real work in his experiments. The moment he and his team cut off the power, the party was over, and the sparks stopped flying. The mainstream continues to try to put the magnetic cart in front of the electric horse, when in fact it works the other way around.

The mainstream really only understands the *B* orientation to Maxwell's equations at the X point, whereas the E orientation is much more useful in terms of calculating circuit energy and in terms of describing the real *work* that is occurring. Maxwell's equations let them "dumb it down" to the B (magnetic) orientation, but that's not what's really driving the process. Electricity and electric fields are actually generating the corona and solar flares as wells as Earth's aurora and changes in the Earth's aurora, not "magnetic reconnection".

Magnetic 'null points' are real however...

That is because the total magnetic field is ZERO at these points. There is no magnetic force.

The field-lines themselves are just imaginary lines. They have NO physical meaning, but
sadly astronomy has mixed them up inside the complex behaviour of plasma.

Change of magnetic field can induce a current: DxE= -dB/dt
So a CHANGING magnetic force causes an electric force.

So due to the interaction between electricity and magnetism (maxwell equations),
if we have flowing particles in the form of plasma or anything else, we have all kinds of side effects.
The electric field caused by the changing magnetic field of the current,
gives a change in the flow of the current, which again changes the magnetic
and electric field.
This produces all kinds of interesting pulsating phenomena as we see on the sun.
In the video you can see how the charged particles move back and forth along certain pathways.
These pathways are not magnetic field lines, because these lines are charged particles. They are visible
because they are electrically active.
To visualize magnetic fields we would need ferromagnetic particles, which are scarce on the sun.
The lines are also layered. Some kind of layering system is going on.
This hints on the fact that not a magnetic field is active, but some bipolar phenomenon.
Mozina already hinted on the "Double layer" system described by Alfven.
The electrons move in spirals in a magnetic field, as we can see in particle accelerators.
The particles do follow some semi-circles. This might hint on huge magnetic fields.
In a single field, many different circles and spirals can be formed.
As you can see in the beginning of the video.

It seems that modern astronomy mixes these spirals and semi-circles of charged plasma, with
the flux-lines that you would see with ferromagnetic material.
But as we can see in the laboratory, a static magnetic field can create
beautiful spirals of charged particles in CERN. (It also works in an old TV).

The black areas on the sun are in 193 angstrom (19.3 nanometer) ultraviolet light.
This means that electrons of 64 electrovolt are less present for some reason.
Why I don't know.

Reconnection occurs between flux ropes to use their Jargon.

Magnetic field line reconnection in the current systems of flux ropes and Alfvén waves

Abstract
Magnetic field line reconnection is still considered, by some, to be one of the most important
topics in plasma physics. It has been in this category for close to 30 years and the ‘problem of
reconnection’ has still not been solved. Magnetic field topologies are part and parcel of the
current systems within a plasma whatever their source. Plasma currents may initially be
induced or injected but they soon become entangled or part of the currents of plasma waves,
flows and structures. We first present experimental results of undriven reconnection, which
occurs when two magnetic flux ropes are generated from initially adjacent pulsed current
channels in a background magnetoplasma (length 18 m, diameter 60 cm). The second example
presented is the three-dimensional (3D) magnetic fields and currents associated with colliding
laser-produced plasmas. The currents in this situation are those of shear Alfvén waves. The
wave magnetic field is a small fraction of the background field; nevertheless, reconnection
regions, multiple magnetic ‘X’ points (which are 3D) and induced electric fields are observed.
The first involves the interaction of magnetic flux ropes and the second localized reconnection
sites in the current system of Alfvén waves
