Why do you even use MHD?

Every time you tweak it something “new” is discovered.

Why do you link to a paper that uses MHD?
Really, the caption of the first figure in this phys.org article reads Reconnecting current sheets and magnetic flux ropes in MHD turbulence.
Everytime it is useful to you, you will accept MHD results a bit more.

So, electric currents, electric fields and electric curcuit.

How will this Tearing instability, apply to the mysterious AGN “Jets”. And their particle acceleration.

The Universe is electric.

Why should there be a tearing mode instability there?

And when a so call “expert” asked, crickets.

Electric currents flow in curcuits...true. You’ve should look it up.

Sure in the laboratory currents flow in circuits, with a battery, a resistance, a inductance, a capacitance, etc. And the current flows in wires, and is ONLY carried by the valence electrons.

In a plasma there are no wires, there are magnetic fields that will hold on to charges, make them run rings around them. But then the charges can still move in all kinds of directions depending on the electric and magnetic fields (something impossible in a lab circuit). In a plasma the charges carrying the currents are electrons AND ions (something impossible in a lab circuit).

Now where does the "circuit representation" come from? This has been explained to you before, but apparently you are not willing to remember it. We take the "whole system" (at least the whole region in which one assumes all processes are taking place) and then look at what in that system can be considered the battery, the resistance, the capacitance, the inductance, etc. and then one can create a representative circuit of that system. Here is a paper by Martens describing a solar flare as a circuit (which is probably the easiest to envision as a coronal loop rather looks like a circuit). With that representative circuit one can calculate some of the properties, e.g. how it will oscillate.

The question for a super duper space plasma physicist such as yourself is.

Why did the plasma current sheet tearing instability be mistaken for “reconnecting” magentic fields?

Are you able to answer?

Of course I am able to answer, but you will not believe/accept my answer.
Nor is "did ... be mistaken" proper grammar.

Nevertheless, the tearing instabiltiy is NEVER mistaken for reconnection. The tearing instability is one of the possible mechanisms that can lead to the onset of reconnection.

All the time, And then demands explanations he does not understand, if he reads them at all.

Nothing new here.

Because mainstream claim “magnetic reconnection”, in the plasmoid/electric current in the AGN regime.

But they are in actual reality are just plasma instabilities. Specifically current carrying instabilities, including the “kink” and “pinch” instabilities because, WHY NOT!

Just because your MHD FORBIDS such things then... update your model peoples.

:D

Understood. Do you even understand? I think not.

The implications here need no math.

Plasmoids appear to be plasma cylinders elongated in the direction of the magnetic field. Plasmoids possess a measurable magnetic moment, a measurable translational speed, a transverse electric field, and a measurable size. Plasmoids can interact with each other, seemingly by reflecting off one another. Their orbits can also be made to curve toward one another. Plasmoids can be made to spiral to a stop if projected into a gas at about 10−3 mm Hg pressure. Plasmoids can also be made to smash each other into fragments. There is some scant evidence to support the hypothesis that they undergo fission and possess spin.

Of great interest is the role the transverse electric field plays in “magnetic reconnection” and particle acceleration.

Plasmoids can and with no math involved, do the following;

Majik!
 
To be clear, your plasmoid quote from wiki is a quote of the abstract of a paper.

from https://doi.org/10.1103/PhysRev.104.292
A plasma gun has been developed which projects ionized matter (metallic and deuterium ions) at speeds up to 2×10^7 cm per second. There is some evidence to support the hypothesis that the plasma projected by this gun comes off in an expanding torus which is shaped by its own magnetic field. When the plasma gun is fired into a dc magnetic field, the plasma forms a compact geometrical configuration (a plasma-magnetic entity called a plasmoid) which proceeds across the magnetic field. Plasmoids appear to be plasma cylinders elongated in the direction of the magnetic field. Plasmoids possess a measurable magnetic moment, a measurable translational speed, a transverse electric field, and a measurable size. Plasmoids can interact with each other, seemingly by reflecting off one another. Their orbits can also be made to curve toward one another. Plasmoids can be made to spiral to a stop if projected into a gas at about 10^-3 mm Hg pressure. Plasmoids can also be made to smash each other into fragments. There is some scant evidence to support the hypothesis that they undergo fission and possess spin.

Did you read the paper?
 
Did we?

So a reconnection of different current sheets... got ya.

Why did mainstream only accept the magnetic bit?

Where do all the current sheet originate and return from? The Helioshpere as detected by Ulysses in the electric currents within a comets tail.

We now these sheets can also be cylindrical in cross section and connect planets to the Sun. Electrically.

Or

Are you still willing to accept snapping field lines as the cause for magnetic reconnection. Jd116 style reconnection.
 
For instance,

INTRODUCTION

Understanding the transfer of energy in magnetohydrodynamic (MHD) turbulence is crucial for tackling many outstanding astrophysical problems, such as solar and stellar coronal heating, star formation, cosmic ray transport, and the interstellar medium evolution. For more than half a century, it has been widely accepted that the energy cascade in turbulent plasmas, such as the Sun’s atmosphere, is controlled by MHD wave interactions (1–3). However, one essential feature of MHD turbulence is the ubiquitous presence of sheets of intense electric current (known as current sheets), which are preferential locations for rapid breaking and reconnection of magnetic field lines (4, 5), a fundamental physical process in magnetized plasmas whereby stored magnetic energy is converted into heat and kinetic energy of charged particles. It is yet an open question whether magnetic reconnection can substantially change the transfer of energy from large to small scales in a wide variety of astrophysical systems.

Understanding MHD? That model is busted.

:rolleyes:
 
Well, now you understand... :)

It’s electric not magnetic.
