Magnetism creates a rotation of the path of the moving particles. It can also create magnetic breaking, like eddy currents. The rotation is always reducing the present magnetic field. That is because of EM and conservation of energy.
You can see that in the video of the article. The current follows circle around the magnetic field. And it is fed from the charged centre.
In the case that the magnetic field is reducing in strength, we get a different reaction. A decreasing magnetic field creates currents that sustain the field. This principle can also cause electromagnetic waves.
The NASA theory is that the plasma somehow sustains the magnetic field. And that this magnetic field is localized to long flux-lines.
Their theory is based on the observation of plasma ropes on the sun. With detectors one can find strong Zeeman effects at the start and end of these plasma ropes. And recently they found even stronger effects at the rope itself. The zeeman effect is related to the magnetic field. So their conclusion is that the rope somehow follows a magnetic field-line. This means that the electrons and ions must spiral through these solar ropes. They also assume for simplicity that no electric fields can exist.
When 2 solar-ropes connect, we sometimes get solar flares. So this creates the idea of magnetic reconnection. Some astronomers even go so far to claim that the flux-lines actually exist. And that these flux-lines create energy with a collision.
But because it is counter our laboratory observations, it seems to me that the problem is a lot simpler. The solar-rope are currents that create magnetic fields instead.
But we can go a small step further. The zeeman effect is also very similar to the Stark effect. And this might indicate that we have strong electric fields at the surface of the sun. And this means we have also found the driving force of the currents inside the solar ropes.
And if 2 solar ropes connect, we will likely have an electrical shortcut. Which is as we all know, very energetic.
But let's use the models on this big solar-rope (Loop) on the sun. https://www.youtube.com/watch?v=HFT7ATLQQx8
We can see movement of plasma very well in this video. The bright plasma follows some curved lines downward and sometimes upwards. You can also see other solar ropes behaving similar.
The plasma is probably fed by dark mode plasma (cloudy area). We see no spiralling. And I have no idea how we can explain this phenomenon with NASA's model.
If I use the corrected model, the plasma simply follows the electric currents. And the plasma follows gravity when it is neutral or almost neutral. That can happen when the particles combine as molecules. The currents create magnetic fields themselves that can cause the curve that we see. So we can expect quite some magnetic field here. The magnetic field even helps the curve to rise up from the surface.
But having other ideas is not the way to get into astronomy.
