FYI, it's going to take me awhile to get through this paper, mostly because it's an EXCELLENT paper and I want to enjoy it. From what I've read so far they described CURRENT and INDUCTION based processes. I haven't been through the whole paper yet, but I'm definitely enjoying it. It's a bit busy at work so bear with me a bit. I will get back to you, but I do want to finish the whole paper. As far as I can tell so far, they are using the term "reconnection" consistently with the way that Somov uses the term. Specifically it's an induced field generation process caused by 'magnetic flux' and particle movements. Cool paper. Thanks again for the reference.

With no math, you can't tell.

With math, plus a smidgeon of freshman (or even high school) physics, you'd know that what you wrote above was laughable.

But you don't bark math, so you have no clue.

My simple derivation of magnetic reconnection is chock full of math. To you, it looks like hand-waving because you can't tell the difference between math and BS.

I showed how a little freshman-level math allows us to reproduce the figures published by Dungey, by Yamada, and by many others who have written papers on magnetic reconnection. You don't understand such advanced math, so you don't understand what my posts have to do with magnetic reconnection or with plasma physics.

Which of your MATHS show a magnetic B line "reconnection" Clinger? Which one results in an ELECTRICAL DISCHARGE in a vacuum? All you've done so far is wave around a little circuit theory, wave around a couple of diagrams related to PLASMA physics and you've shown no actual B field line reconnection that might explain million degree solar flares, nor have you shown that any field BEGINS in your X point nor ENDS in your X point. So far the math you have provided is CHILDISH.

This is an empirical experiment creating magnetic re-connection in the lab using helium plasma and lasers.
This is a LONG paper, but I pulled a line from the abstract that applies here:

Quote:
A reconnection event is triggered by the collision and the electric field induced in this event generates a field-aligned current, which is the first step in the development of a fully three-dimensional current system.
I'm totally fine with the concept of "current reconnection', or even "field aligned current reconnection" as long as there is SOME MENTION of the current that does the 'reconnecting". This paper thus far is 100 percent consistent with Somov's presentation of field aligned current reconnection in chapter 16. This is essentially "standard stuff", but it's also directly related to a "current system", not just simple magnetic B lines. I'm fine with their use of INDUCED E fields. It seems to be another EXCELLENT presentation from UCLA. It's a great paper, but it's more based upon induced currents. I"m not quite done yet, but I don't think this actually helps your case.

I don't have that book, I only have plasma astrophysics, in which electical discharge is never useds.
And yes there are currents in the reconnection region, and no they cannot create the change of topology of the magnetic field as in reconnection.
I notice that everything is again in quotation marks, so it could be your own definitions.
At one point you really have to give a complete description of what you think is happening.

And in fact it is the case, and the whole of Somov's book is showing reconnecting B lines, if you like it or not. But keep in your denial, it is more than a river in Egypt.

That all depends, if you have a two currents like in Geemacks figure then there is a current along a rod or a field in the lab. and then you have to look at the superposition of this field and the generated circular field giving a spiral. Between the two spirals (separating them for the moment) there is also plasma and that is flowing perpendicular to the field as it should because of Maxwell.

However, that is not easy at all. The easiest way is the Earth's magnetotail where oppositly directed field is on top of eachoter separated by a current sheet perpendicular to the magnetic field. Then you have the simple petchek reconnection and unless you understand what happens in such a simple model, you cannot even start to understand what is happening in the more complicated lab set-up.

Dungey used math. That didn't convince GM that electrical discharges occur in flares. Alfven used math to do away with the whole need for 'magnetic reconnection" theory in current carrying plasma and that didn't convince anyone. Unfortunately all the math in the world is at their fingertips, but none of them understand it or bother reading it. Ask Clinger if electrical discharges occur in solar flares? He's been riding Dungey's coattails with this so called "experiment". Does he also agree with Dungey that electrical discharges occur in plasmas and solar flares? Does RC agree? What use is math when none of them are even interested in reading a book on plasma physics? They have all the math in the world at their feet. The refuse to read or comprehend any of it.

Could you start by explaining to me why it's impossible for one electron or charged particle from one field aligned current to physically jump current streams and "reconnect" with the other one? IMO from your last response, this is our basic area of disagreement. I'd rather we focus on one issue at a time.

FYI, Clinger also convinced him that solid magnet reconnection was the same thing as an electrical discharge in a plasma too. People in herd mentalities tend to convince each other of just about anything and everything. Math is optional in my experience, particularly when dealing with "haters" (hate being wrong, hate EU theory/evolutionary theory/whatever).

FYI, forget my earlier comments about that most recent paper by W. Gekelman, A. Collette, and S. Vincena being "basic stuff". Wow. This is REALLY an INCREDIBLE paper. The images they create are absolutely fabulous, and the depth of this paper is REALLY impressive. Two thumbs up! (Still doesn't help your case though).

There is SOME MENTION of the 3D current system that does not do the 'reconnecting". The reconnection event comes first, then an induced electric field (during the event) and then the development of a fully three-dimensional current system.

He states that
  1. Magnetic reconnection is the cause of solar flares.
  2. The term 'electrical discharge' in the context of his paper means a large current density.
  3. Large current densities ('electrical discharge') happen during the MR that cause solar flares.
Thus in the 1950's , MR caused 'electrical discharges' to happen in solar flares.

But this is a 60 year old use of the term. It is no longer used.
Thus in 2011, MR causes high current densities to happen in solar flares and there are no 'electrical discharges'.

According to your rather unique point of view, somewhere between the 1950's and today, 'electrical discharges' ceased to to happen in solar flares !

What really happened is that scientists realized that using the term 'electrical discharge' to mean a large current density was confusing because it already had a standard definition (see Anthony Peratt's definition of electrical discharge). So they now use current density instead as far as I have seen.

Dungey's 'electric discharge' = large current density in magnetic reconnection!

Since he's riding Dungey's coattails, handwaving away like crazy, talk to me again when he produces an electrical discharge from his vacuum contraption and he provides us the additional math we're waiting on.

So you now agree that solar flares are in fact "electrical discharges" in the solar atmosphere.

The term "reconnection" relates to an inducement of an E field due to FLUX and an ensuing electrical discharge. It has NOTHING to do with reconnecting B lines!

Who cares? Talk about pathetic rationalizations. Somehow the PROCESS is different today I presume?

A pity that you cannot read - this INCREDIBLE paper is about an MR experiment !
It mentions reconnection 30 times.
Abstract:
Quote:
A reconnection event is triggered by the collision and the electric field induced in this event generates a field-aligned current, which is the first step in the development of a fully three-dimensional current system.
...
As local currents move, small reconnection “flares” occur at many locations throughout the volume, but they do not seem to affect the overall system dynamics.

Introduction:

Quote:
In the present experiment, colliding plasmas produce effects not seen in a single lpp expansion. An intense current channel generated by magnetic field reconnection occurs when the plasmas collide.

Since you are impressed by the images, you will really be impressed by Fig 8: "The field lines are colored according to the local magnetic field in G. Two reconnection regions are visible above and below the central current channel."
(emphasis added).

What exactly don't you understand about the word "current"? They are clear that what "reconnects" are "field aligned currents". I have no idea what you think they said, but there is no way in hell you've been through that paper yet and actually UNDERSTAND it.

You claim that 'electrical discharges' happen in solar flares because you can cite a 60 year old paper where the term 'electrical discharges' was used for the large current density caused by the MR that causes solar flares.
But this term is no longer used in the modern papers about MR as a cause of solar flares. So 'electrical discharges' no longer happen in solar flares. The term has been replaced by large current densities.

One more time:
In the 1950's some authors desccibed large current densities caused by MR in solar flares = 'electrical discharges' caused by MR in solar flares.
Today there is no sign of any author using the term 'electrical discharges' in the context of MR causing solar flares.

Thus my coment:

What exactly about the sequence of events in the sentence you picked out can you not understand?

There is no way in hell that you cannot understand that there is no reconnection of field-aligned currents in that sentence.
There is a reconnection event that induces an electric field. The electric field generates a field-aligned current.

The "Summary and Conclusions:" makes this even more explicit:
Quote:
Two carbon laser-produced plasmas with initial density that is orders of magnitude greater than an ambient helium plasma were produced such that they collided in the center of the plasma column. The collision process occurs in two stages. In the first, two magnetic “bubbles” collide. The collision produces turbulent local magnetic fields. The morphology and wavenumber spectrum of this turbulence will be the subject of a future paper. The collision of the lpps results in an early magnetic reconnection event (Fig. 4). This creates a short-lived induced electric field parallel to the background magnetic field and drives a large field aligned current. After about a microsecond, the magnetic bubbles collapse but the cross-field collision continues. In the final state, the two plasmas coalesce and stream along the magnetic field away from the impact point.
(emphasis added to match my emphasis in the abstract)

It is idiocy to think that a large current density (Dungey's 'electrical discharge' term that is no longer used) in plasma in an experiment that has no plasma (is in vacuum) !

There is a reconnection event that induces an electric field. The electric field generates a field-aligned current.

The "Summary and Conclusions:" makes this even more explicit:

(emphasis added to match my emphasis in the abstract)
Anyone can parrot the term "reconnection" RC. The term is technically "magnetic reconnection", not "magnetic B LINE reconnection". Nobody disputes the fact that magnetic field FLUX can INDUCE (not reconnect) E fields which result in electrical discharges in plasma RC (except you). Nobody has shown any math to demonstrate that B field lines "reconnect".

You are lying - W.D. Clinger has. He has used math to describe the physics of the EM fields generated by current carrying rods.

W.D. Clinger has demonstrated that you can have a magnetic field topology that matches Dungey's and Yamada et al 2010.

I didn't call them parrots. They UNDERSTAND and explained the process clearly and BEAUTIFULLY. It's you that keeps parroting the term "reconnection" without any understanding of what you're talking about. They are talking about induced E field and field aligned current reconnection. You're still clueless because you believe that B field lines 'disconnect' even though they have no beginning and no ending. Evidently you also buy Clinger's BS about them "beginning" and "ending" in a "vacuum" no less. Talk about ditzy beliefs.

I will explain that in part 5 of my simple derivation of magnetic reconnection.

Thank you for acknowledging that all of the B fields I have diagrammed are relevant to plasma physics.

In part 4 of my simple derivation of magnetic reconnection, I will prove that the magnetic field lines of a B field can reconnect. As I am not a physicist of any kind, I will not try to show that magnetic reconnection can explain hot solar flares. I'm just trying to counter some of the denialist noise by posting a simple derivation of magnetic reconnection as discussed by Dungey, Yamada, and the current Wikipedia article on magnetic reconnection.

Although I have shown computer-generated graphs of the B field and some of its magnetic field lines, including the four magnetic field lines that begin or end at the neutral point of the X-shaped field in Dungey's figure 1, it is true that I have not shown every single step of the calculations that prove those lines begin or end at the X point.

On the other hand, I have stated all of the relevant equations, and I have explained how you can complete the proof yourself by calculating B's partial derivatives along the diagonals. That seems like a trivial calculation to me, but I can understand how it might be impossible for you.

If you knew anything at all about the subject in which you're pretending to be such an expert, you'd know that an unchanging magnetic flux does not induce an E field.

So what? He's never demonstrated that B field lines "reconnect" nor that they have a 'beginning' or an 'ending' inside of a VACUUM no less. He's buried himself in BS handwave claims that he can NEVER demonstrate mathematically.

Until you and/or Clinger has answered EVERY SINGLE ONE of the questions from that last list of questions, you two have done absolutely NOTHING in terms of showing "B field line reconnection", not to mention any of those BS claims about magnetic lines beginning and ending in a vacuum.

Lovely. I can't wait. I guess it will explain that confusion with the arrows at the X and it will explain how magnetic lines "begin" in a vacuum too I presume?

Your arrows at the X are FUBAR to this point in time since you have no plasma as Dungey did and no mathematical explanation for them. I have idea how you intend to justify your two directional arrows. I'll have to wait and see I suppose.

Quote:

Oh, so part 5 is one gigantic goalpost shift where you try to HIDE the fact that you finally realize that you NEED a plasma and your experiment doesn't actually WORK in a VACUUM as you first claimed? Is that it? Ah, the back-peddling and rationalizations have already begun I see. How sadly predictable.

Duh - I read and quoted the authors talking about induced E field and field aligned current!

You are still ignoring the reconnection event that comes before the field aligned current is created.

You are lying - there is no "field aligned current reconnection" unless you can answer:

Strawman. I didn't say a damn thing about "unchanging", you did. In fact you painted yourself into a corner by changing dB/dt slowly, remember?

The confusion with the arrows is all yours. It has been explained previously.
That magnetic field lines begin and end in in the magnetic field configuration (that happens to be in a vacuum) is easy so see - no field lines at the neutral point = they have to begin or end there.

Not a strawman.
It was you who have constantly neglected to mention a changing magnetic flux. Instead you have been going on about 'magnetic flux' and not stating that it was changing.
It is obvious that in magnetic reconnection, magnetic fields are changing and so magnetic flux through a given surface can be changing.
But Faraday's law of induction is
Quote:
and inducted E fields are generated from changing B fields.

Your last sentence displays some ignorance.
Magnetic flux is not dB/dt. It can change when B changes but does not enter into the induction of E fields.
Magnetic flux "(most often denoted as Φm), is a measure of the amount of magnetic B field (also called "magnetic flux density") passing through a given surface (such as a conducting coil)."

If by 'demonstrated' you mean 'detailed every step so that a child can understand it' then W.D. Clinger (and no one else) will ever be able demonstrate it.
If by 'demonstrated' you mean 'detailed every step so that Michael Mozina can understand it' then W.D. Clinger (and no one else) will ever be able demonstrate it because you have an displayed an abysmal ignorance of the physics and mathematics required to understand it.
Michael Mozina's ignorance of high school science (the right hand rule)
Michael Mozina's delusion that permeability is inductance!
Michael Mozina's delusion about "*RECONNECTIONS* per unit length").
If by 'demonstrated' you mean 'detailed every step so that Michael Mozina can accept it even if he cannot understand it' then W.D. Clinger (and no one else) will ever be able demonstrate it because you have an displayed an obsession with not accepting MR, e.g. ignoring or misinterpreting the scientific literature on it.

Oh my goodness. Is Michael Mozina really suggesting that Reality Check or I might have the slightest difficulty with a calculation he is utterly unable to perform?

To complete a rigorous proof that two magnetic lines of B4 end at the neutral point, and another two magnetic lines begin at the neutral point, we need only calculate the partial derivatives of B4 along the diagonals and draw the obvious conclusions.

Here's the definition of B4:

&= \frac{\mu_0}{2 \pi} \frac{I^{(p)}(t)}{(x-x_0)^2+(y-y_0)^2}<br />
\left( - (y-y_0) \, \hbox{{\bf e}}_x + (x-x_0) \, \hbox{{\bf e}}_y \right)<br />
\end{align*}<br />
\]<br />
where ex and ey are the unit vectors in the x and y directions.


Magnetic fields around multiple rods

Applying that equation to our four rods, we define
<br />
\[<br />
<br />
\begin{align*}<br />
p_E &= \langle 1, 0 \rangle \\<br />
p_W &= \langle -1, 0 \rangle \\<br />
p_N &= \langle 0, 1 \rangle \\<br />
p_S &= \langle 0, -1 \rangle \\<br />
I_E(t) &= I^{p_E}(t) = \hbox{{1000 amperes}} \\<br />
I_W(t) &= I^{p_W}(t) = I_E(t) \\<br />
I_N(t) &= I_S(t) = - I_E(t) = - I_W(t) \\<br />
\hbox{{B}}_E &= \hbox{{B}}^{(p_E)} \\<br />
\hbox{{B}}_W &= \hbox{{B}}^{(p_W)} \\<br />
\hbox{{B}}_N &= \hbox{{B}}^{(p_N)} \\<br />
\hbox{{B}}_S &= \hbox{{B}}^{(p_S)} \\<br />
\hbox{{B}}_2 &= \hbox{{B}}_E + \hbox{{B}}_W \\<br />
\hbox{{B}}_4 &= \hbox{{B}}_E + \hbox{{B}}_W + \hbox{{B}}_N + \hbox{{B}}_S<br />
\end{align*}<br />
\]<br />
To calculate ∂B4/∂x and ∂B4/∂y, Reality Check and I would have to know how to
  • calculate the partial derivatives of a sum
  • calculate the partial derivatives of a quotient
  • calculate the partial derivatives of a composition (using the chain rule)
  • calculate the partial derivatives of a low-order polynomial
To us, that looks like a trivial exercise in first-semester calculus. No wonder it looks so hard to Michael Mozina.
