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.

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.

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.

In chapter 16 of "Fundamentals of Cosmic Electrodynamics" Somov relates the whole process back to the E orientation, and uses the term "field aligned currents". In fact the chapter itself is entitled "Reconnection of electric currents". As I've said all along, I'm fine with that view of the process. I'm fine with "current reconnection" or "circuit reconnection". 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. Originally Posted by Michael Mozina I'm not fine with the term "magnetic reconnection" because it implies something that is misleading, specifically it implies B line reconnection, when in fact that is not the case. 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. Originally Posted by Michael Mozina I'm trying to look for a rational way to bridge our differences here. Let's start "easy". Would you agree that *BEFORE* the reconnection process begins, the plasma is flowing in two field aligned currents? 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. __________________ 20 minutes into the future This message is bra-bra-brought to you by z-z-z-zik zak And-And-And I'm going to be back with you - on Network 23 after these real-real-real-really exciting messages (Max Headroom) follow me on twitter: @tusenfem, or follow Rosetta Plasma Consortium: @Rosetta_RPC

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.

The term 'electrical discharge' in the context of his paper means a large current density. 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.

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!

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.

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. Originally Posted by Michael Mozina So far the math you have provided is CHILDISH.

Deliberate misrepresentation of others' conversations is a form of lying. Originally Posted by Michael Mozina 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! Originally Posted by Michael Mozina 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". 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.

Nope: http://www.internationalskeptics.com...postcount=4723 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.

Quote: Although I have explained how the B fields shown in Dungey's two figures can be replicated by the simple experiment I suggested to you last December, I have not yet explained their relevance to increasing current density at the neutral point (which is what Dungey meant by electrical discharge). 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: I will explain that in part 5 of my simple derivation of magnetic reconnection. 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. Last edited by Michael Mozina; 8th November 2011 at 04:44 PM.

Originally Posted by W.D.Clinger I have already sketched a geometric proof that Gauss's law holds for the magnetic field generated by a single current-carrying rod.

That result can also be confirmed by starting from the equation for B4 and calculating its divergence. As for your fantasy that there is plasma in his experiment to create Dungey's outdated term for large current density: Originally Posted by Reality Check 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) ! __________________ NASA Finds Direct Proof of Dark Matter (another observation) (and Abell 520) Electric comets still do not exist!

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. __________________ NASA Finds Direct Proof of Dark Matter (another observation) (and Abell 520) Electric comets still do not exist!

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)." __________________ NASA Finds Direct Proof of Dark Matter (another observation) (and Abell 520) Electric comets still do not exist!

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: Originally Posted by W.D.Clinger  \begin{align*} \hbox{{\bf B}}^{(p)} &= \hbox{{\bf B}}^{(p)} (x, y, z, t) = \hbox{{\bf B}}^{(p)} (t) (x, y, z) \\ &= \frac{\mu_0}{2 \pi} \frac{I^{(p)}(t)}{(x-x_0)^2+(y-y_0)^2} \left( - (y-y_0) \, \hbox{{\bf e}}_x + (x-x_0) \, \hbox{{\bf e}}_y \right) \end{align*}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  \begin{align*} p_E &= \langle 1, 0 \rangle \\ p_W &= \langle -1, 0 \rangle \\ p_N &= \langle 0, 1 \rangle \\ p_S &= \langle 0, -1 \rangle \\ I_E(t) &= I^{p_E}(t) = \hbox{{1000 amperes}} \\ I_W(t) &= I^{p_W}(t) = I_E(t) \\ I_N(t) &= I_S(t) = - I_E(t) = - I_W(t) \\ \hbox{{B}}_E &= \hbox{{B}}^{(p_E)} \\ \hbox{{B}}_W &= \hbox{{B}}^{(p_W)} \\ \hbox{{B}}_N &= \hbox{{B}}^{(p_N)} \\ \hbox{{B}}_S &= \hbox{{B}}^{(p_S)} \\ \hbox{{B}}_2 &= \hbox{{B}}_E + \hbox{{B}}_W \\ \hbox{{B}}_4 &= \hbox{{B}}_E + \hbox{{B}}_W + \hbox{{B}}_N + \hbox{{B}}_S \end{align*} To calculate ∂B4/∂x and ∂B4/∂y, Reality Check and I would have to know how tocalculate 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.
