Because these old JREF posts by actual astrophysicists reveal just how bad some of the past statements you have made about magnetic reconnection were, e.g. the really ignorant induction stuff, Michael:Why?
I have in fact supported my claim with several published references to magnetic reconnection in a vacuum. Here is a list of my posts on the topic, which the industrious reader may wish to peruse for the various references therein.

Still wrong, Michael: That is part of a definition of electrical discharge. No mention of plasma in that part of a definition. Some simple English for you, Michael, plasma is a word that does not appear in the text you highlightedAnthony Peratt's definition of electrical discharges in plasma:
An electrical discharge is a sudden release of electric or magnetic stored energy. This generally occurs when the electromagnetic stress exceeds some threshold for breakdown that is usually determined by small scale properties of the energy transmission medium.
Michael still cannot understand after a couple of years that "actual electrical discharges" = lightning etc.!
We either have that Anthony Peratt is the only scientist in the worldeek according to you Michael who thinks that lightning is possible in plasma....
Based on 26th September 2011: Where is the discussion of 'electrical discharges in plasma' in any other textbook?
We either have that Anthony Peratt is the only scientist in the worldeek according to you Michael who thinks that lightning is possible in plasma or that it is common knowledge that lightning is possible in plasma. That means that there will be many textbooks stating this.
Peratt's book was published in the 80's. It was not the first plasma physics textbook ever published!
Peratt's book was published in the 80's. In the last 30 years, many textbooks have been written on plasma physics. They should all include that all important 'electrical discharges in plasma' chapter with all of the physics and mathematics.
26 September 2011 Michael: Where is the definition, discussion, examples, etc. of 'electrical discharges in plasma' in any other textbook.
20th March 2012: Michael Mozina's idea that a reconnection rate exists without plasma
with the inability to answer a simple question:
20th March 2012 Michael Mozina, What is the Alfvén speed for a vacuum?
has 'plasma is a current' fantasy replies.
You need to learn some English and physics, Justatruthseeker.They do.
Michael's denial of science and English about MR in vacuum continues:
Cosmic plasma physics By Boris V. Somov has 2 sections called "4.4.2 Reconnection in vacuum" and "4.4.3 Reconnection in plasma".
The only "fantasy" in play is your fantasy about thinking that you understand plasma physics without ever educating yourself to the topic.
Those A) *currents* that Somov included in his "vacuum", and B) the movement of those currents are what differentiate your "toy" version of "reconnection" (AKA magnetic flux in a vacuum) from the "real" plasma physics process called "magnetic reconnection". Even Priest explained the difference between a *real* understanding of magnetic reconnection and a *toy/pretend* understanding of reconnection theory. The *real* one *requires* plasma, whereas toys are simply *toys*!
You apparently don't comprehend the meaning of a scientific debate. Handing me links to *yourself* and some *random website* is not a "scientific debate". Scientific debates require *published* material, like Dungey's electrical discharges in solar flare paper. You keep citing yourself and *unplublished materials*. Notice a problem? I sure do. Apparently you're incapable of citing any reference that claims that "real" reconnection is a plasma optional process. Preist's paper even clearly differentiated between *toys* and *real* processes, but you simply ignored it. You heard the term "vacuum", and ignored the word *toy* entirely. Your selective listening skills are just pathetic.
Michael's denial of science and English about MR in vacuum continues...usual insults and delusion about electric currents being plasma snipped...
Justatruthseeker: What is worse is people who read plasma textbooks and persist with delusions about magnetic reconnection in vacuum that looks based on ignorance about what plasma isYes, people never bother to read about plasma physics, then think they understand how it behaves.
No plasma in the example - just a vacuum and two parallel, equal electric currents.Chapter 4. Motion of a Particle in a Field
4.4.2 Reconnection in Vacuum.
X-type points consist a topological peculiarity of a magnetic field. They are places where where redistribution of magnetic fluxes occurs, which changes the connectivity of field lines. Let us illustrate such a process by the simplest example of 2 parallel electric currents of equal magnitude I in vacuum as shown in Figure 4.17. The magnetic field of these currents forms three different fluxes in the plane (x,y). Two of them belong to the upper and the lower currents, respectively, and are situated inside the separatrix field line A, which forms the figure of the eight-like curve with zeroth X-point. The third flux belongs to both currents and is situated outside of the separatrix.
If the currents are displaced in the direction of each other, then the following magnetic flux redistribution will take place. The currents proper fluxes will diminish by the quantity dA, while their common flux will increase by the same quantity. So the field line A2 will be the separatrix of the final state.
This process is realized as follows: Two field lines approach the X-point, merge there, forming a separatrix, and then they reconnect forming a field line which encloses both currents. Such a process us termed reconnection of field lines or magnetic reconenction. A2 is that last reconnect field line.
Magnetic reconnection is of fundamental importance for the nature of many non-stationary phenomena in cosmic plasma. We shall discuss the physics of this process more fully in chapters 16 to 22. Suffice it to say that reconnection is inevitable associated with electric field generation. The field is the inductive one, since
[equation 4.65]
where A is the vector potential of magnetic field,
[equation 4.66]
In the above example, the electric field is directed along the z axis. It is clear if that if dt is the characteristic time of the reconnection process shown in Figure 4.17 then according to (4.65)
[equation 4.67]
the last equality will be justified n Section 9.2
Reconnection in vacuum is a real physical process: magnetic field lines move to the X-type neutral point and reconnect in it as well as
| the electric field is induced and can accelerate a charge particle or
| particles in the vicinity of the neutral point.
Yes, people never bother to read about plasma physics, then think they understand how it behaves. Treating it like dust and gas and wondering why they require 95% ad-hoc fluff. My bad, they don't even wonder why, they just religiously believe they need all that ad-hoc fluff, because they fail to understand plasma physics in the slightest.
Michael's denial of science and English about MR in vacuum continues!
I am rather shocked that you do not know that an electric current is not plasma, Justatruthseeker.
Just how deluded is the statement that "electric currents are plasma", especially in the context of Somov's example of magnetic reconnection in vacuum where the magnetic fields are generated by two parallel, equal electric currents?
Some rather incoherent posts just repeating the delusion that MR in vacuum includes plasma, Michael....posts repeating the same delusions...
