I think it's you who doesn't know what he's talking about if you think flux and reconnection could somehow be confused with each other.

The mathematical representation of those magnetic fields is what we call magnetic field lines. Maybe it's difficult for some people to understand because it's a math thing. Quote: Both magnets have a full field around them. They can even physically "reconnect" when the physical magnets "reconnect". The mathematical representation of those magnetic fields is what we call magnetic field lines. The magnets don't have to touch for the field lines to change. When the magnets are moved apart those field lines do not simply get longer and longer and eventually extend onward to infinity. And in particular when one magnet is moved away from another then brought into the proximity of a third magnet, the field lines disconnect and reconnect. It can be done with a couple of refrigerator magnets. The results can be seen in a grade school experiment with some magnets, a piece of paper, and some iron filings. Maybe it's difficult for some people to understand because it's a math thing.

No current is induced as Sweet states, and no "electrical discharge" could occur as Dungey describes. Sheesh! magnets and fields are experiencing magnetic flux?????????? Magnetic flux is, to use words, the number of field lines that cross through a unit surface, it is a value, it cannot do anything, whatsoever. In math, if you can understand it, magnetic flux is: $ \Phi = \int \int {\bf B} \cdot d{\bf S}$ Flux can increase, or decrease, but it is just a number, nothing more nothing less. If you want to have a real scientific discussion, then get your terms correct. __________________ 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 Last edited by tusenfem; 2nd March 2012 at 03:37 PM.

 2nd March 2012, 03:36 PM #6608 Perpetual Student Illuminator     Join Date: Jul 2008 Posts: 4,852 So, I have not recieved a response from Mozina to my questions about Priest's paper. Specifically, I would like to learn how equations 16 and 17 from Priest's paper prove that plasma is required for reconnection. The first step is for me to understand the equations, so looking at equation 16 for starters, I have asked for Mozina to help define the terms in that equation. So far I've had no response. Since these equations are so straightforward in proving the requirement for plasma and Mozina is an expert in this area, it should be quite easy for him to help define the terms. So, again, Mr. Mozina, tell me about $\alpha$ and $\phi_r$ in the following equation 16: $\mu_0I(z) = 4\pi\alpha^{-1} cos(\alpha|z| +\phi_r)$ Either define these two terms or show me where they are defined so we can have a meaningful discussion and you can share your knowledge about this equation. __________________ It doesn't matter how beautiful your theory is, it doesn't matter how smart you are.

Any change in the topology of the magnetic flux is magnetic reconnection by definition. See my earlier post Magnetic Reconnection Defined and Described (24 January 2012). The terms "magnetic flux" and "magnetic field" are related to each other as shown by the passages below ... Originally Posted by "Electromagnetic Fields and Waves", Lorrain & Corson, 1970, chapter 7 The next three chapters will deal with various aspects of magnetic fields. We shall start by studying in some detail the properties of two vector quantities, namely, the magnetic induction B and the vector potential A, which are used to describe magnetic fields. { ... } As in electrostatics, where we used lines of force to describe an electric field, we can describe a magnetic field by drawing lines of B that are everywhere tangent to the direction of B. Similarly, it is convenient to use the concept of flux, the flux of the magnetic induction B through a surface S being defined as the normal component of B integrated over S: $\phi = \int_s \bold B \cdot \bold {da}$ In Classical Electrodynamics by John David Jackson (John Wiley & Sons, Inc., 1999, 3rd edition), he uses the term "magnetic flux density" ... Originally Posted by Jackson, 1999 Already in the definition of the magnetic-flux density B (sometimes called the magnetic induction), we have a more complicated situation than for the electric field. It is not clear to me that you are using the term "magnetic flux" properly. These two quotes show the proper context of the terms, flux, flux density and induction, for magnetic fields. What is evident is that B, which we call the magnetic field, is related to flux by a simple surface integral. Change the topology of B and you will change the topology of its integrated flux. Likewise, if you want to change the topology of the integrated flux, you have to change the topology of B. The mathematical representation of this change in topology is by reconnection of the lines of force. This is a point I have made several times now, evidently to no avail. Of course the physical magnetic field is a continuum, nobody ever disputed that. However, also see my earlier post Magnetic Field Lines and Flux Tubes Defined, where we see Biskamp define a field line as a flux tube of infinitesimal diameter. But consider this ... Originally Posted by Michael Mozina Even still, "reconnection" requires PHYSICAL THINGS ... Magnetic fields exist and are physical things with topology. There is no law of physics which prevents the physical thing we call a magnetic field from altering its topology in a vacuum; there are laws of physics which require the topology of he magnetic field to change in a vacuum (Specifically Maxwell's equations in a vacuum). In what sense do you assert that a magnetic field is not a "physical thing"? Finally, it would surely clear things up a lot if Mozina chose to respond to this ... Originally Posted by Tim Thompson Originally Posted by Michael Mozina I do not reject the math's associated with "reconnection" theory either Tim. I reject the STUPID NAME you folks assigned to the PLASMA PROCESS. OK. Reference my post Magnetic Reconnection Defined and Described In the paper Magnetic Reconnection by Yamada, Kulsrud & Ji, we find this statement: "Understanding magnetic reconnection, a topological rearrangement of magnetic field lines, provides a key to these questions. In magnetized astrophysical and laboratory plasmas, magnetic reconnection rearranges the magnetic field-line configurations restructuring macroscopic quantities of plasmas such as flow and thermal energy." Do you agree with this? Specifically, do you agree that the magnetic field lines reconfigure to change the topology of the magnetic field? In the book Magnetic Reconnection: MHD Theory and Applications by Priest & Forbes we find this statement: "As we shall discuss in more detail later on, magnetic reconnection is essentially a topological restructuring of a magnetic field caused by a change in the connectivity of its field lines. This change allows the release of stored magnetic energy, which in many situations is the dominant source of free energy in a plasma." Do you agree with this? Specifically, do you agree that the change in the topology of the magnetic field is caused by changes in the connectivity of the magnetic field lines? In the paper Review of controlled laboratory experiments on physics of magnetic reconnection by Masaaki Yamada we find this statement: "Magnetic reconnection is the topological breaking and rearrangement of magnetic field lines in a plasma and is the most fundamental process in the interplay between plasma and magnetic field (Parker, 1979; Priest, 1984; Vasyliunas, 1975)." Do you agree with this? Specifically, do you agree that the magnetic field lines break and then rearrange into a different topology? The plasma processes associated with magnetic reconnection happen because first the topology of the magnetic field changes to that of a lower energy state and then the energy is transferred to the plasma which reacts accordingly. So why is "magnetic reconnection" a "stupid name", when it is in fact the root cause of the plasma process to begin with? And if in fact you accept the math, as you claim you do, and the math shows field lines reconnecting, then again, why is it a "stupid name"? __________________ The point of philosophy is to start with something so simple as not to seem worth stating, and to end with something so paradoxical that no one will believe it. -- Bertrand Russell

It's not a complicated concept, it can be done in a sentence. You don't want to address the REAL PHYSICS issue. You will not accept the *FUNDAMENTAL PHYSICAL DIFFERENCE* between a "vacuum" and a plasma as the magnetic fields are being changed. If you start rotating those magnets inside of a vacuum, no currents are going to be induced in the vacuum, therefore no DISCHARGES/RECONNECTION processes can occur. You can't and won't embrace the mathematical evidence, all of which OVERWHELMINGLY (thousands to none) demonstrate that reconnection *REQUIRES* (fundamentally requires) PLASMA. MHD theory is all about PLASMA PHYSICS! Those maths that are related to "reconnection" are all based upon the behaviors of PLASMA and movements of PLASMA! Come on!

You can't go on because your show falls apart if you do. Who do you think you fooling? And yet it's not the people pointing out the failure of the against-the-mainstream proponents who are fixated on some archaic and dishonestly cherry-picked meaning for the term "discharge". Quote: Plasma (a conductor) is not OPTIONAL in the "reconnection" process. The magnetic fields change over time. In a CONDUCTOR that change over time int the field location INDUCES current in the conductor. Plasma is optional in the magnetic reconnection process, as anyone with the brains and gumption to perform the grade school kid experiment described before wshould understand. Quote: In a vacuum, *NOTHING* but flux. No induced current in the vacuum, no discharge in the vacuum. In a vacuum? If an astronaut took those grade school kids' magnets out on a space walk, that very same magnetic reconnection experiment would produce virtually the same results. Magnetic reconnection would occur, demonstrably, objectively. Quote: You folks cannot handle the truth. You therefore look for ANYTHING I say to TWIST LIKE A PRETZEL to suit yourselves. It doesn't take twisting. It's so wrong, not to mention incredibly uninformed and dishonestly assembled, that it starts out twisted. Quote: I'm definitely wasting my breath here. That seems like a reasonable assessment since the failure has been absolute. The entire argument to support an electric/iron Sun conjecture is based on misunderstanding a couple pictures and cherry-picking a half dozen documents, some over a century old. And each additional breath only results in more failure.

Furthermore, not being a physicist, I don't understand why the current, as a function of the position along the z axis, is multiplied by $\mu_0$ (the magnetic constant). Do you?

 2nd March 2012, 09:25 PM #6626 Perpetual Student Illuminator     Join Date: Jul 2008 Posts: 4,852 I have given Mozina a golden opportunity to demonstrate that his theory about reconnection has some merit. He has been adamant that the two equations (numbered 16 and 17) from Demoulin's and Priest's 1992 paper prove that reconnection cannot happen without plasma. My requests to review and discuss the equations so we can fathom their meaning and glean how they provide this proof have gone unanswered. Why would he pass on this opportunity to put this question to rest and vanquish all the doubters here? Could it be that the two equations at issue do not provide the alleged proof? Could it be that Mozina's ignorance of mathematics and physics renders him incapable of discussing these equations? Could the answer to both these statements be a resounding "yes," exposing Mozina and his theories as so much blather and wind? __________________ It doesn't matter how beautiful your theory is, it doesn't matter how smart you are.

NO, it is just because you don't understand electrodynamics, let alone plasma physics, that you discard any source about how magnetic fields work in a vacuum. Like Sweet, like Yamada et al., like Birn, etc. etc. Let's mention Dorelli et al. 2007 here. Ofcourse, because of the triviality of vacuum reconnection, nobody really looks at that, it first becomes interesting when plasma is present, however vacuum superpostition models are usually always the starting point for modeling. __________________ 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 Last edited by tusenfem; 3rd March 2012 at 05:48 AM.

Magnetic flux is, to use words, the number of field lines that cross through a unit surface, it is a value, it cannot do anything, whatsoever. In math, if you can understand it, magnetic flux is: $ \Phi = \int \int {\bf B} \cdot d{\bf S}$ Flux can increase, or decrease, but it is just a number, nothing more nothing less. If you want to have a real scientific discussion, then get your terms correct. Originally Posted by tusenfem If you really don't know what the difference is between magnetic flux and magnetic reconnection you really are a lost cause, and apparently never ever read a book on plasma physics. The fallacy of equivocation rests entirely with you & you alone. You are the one who is guilty of the misleading use of the term "flux". As for my definition of magnetic reconnection, there is neither equivocation nor ambiguity, and I once again refer the reader to my post from 24 January, Magnetic Reconnection Defined and Described as an objective substantiation of my assertion.

It's called "induction". It most certainly is not. And to the surprise of no one, we have already been down this road. The key to understanding why it cannot be induction is that induction can change only the geometry of a magnetic field, but can never change its topology. From 24 December 2009, over two years ago ... Originally Posted by Tim Thompson Originally Posted by Michael Mozina Yet you won't personally explain what's unique about magnetic reconnection, so what can I say Tim? That's not true, and you know it. It's no wonder that people keep calling you a liar. Are you trying to add me to the list? I have already done that many times. I said it was a change in the topology of the magnetic field, and that certainly is not induction by any stretch of the imagination. Besides, induction is strictly limited by the diffusion timescale of the plasma, whereas reconnection is impulsive. The two processes are distinctly different both in theory and in practice. Impulsive energy release, such as a solar flare, is quite impossible for any induction process. Had you bothered to read any of the source material you have been directed to (for instance the book Magnetic Reconnection by Priest & Forbes) you would already know this, since it is spelled out in detail (I would be more specific but I am 1000 miles from home and the book at the moment). That's why I say I don't believe you when you say you are really interested in learning. Anyone truly interested in learning would naturally consult the books & papers they are referred to. I see no indication that you do that. As it stands, you appear to implicitly assert that you know more about physics than everyone else, and simply ignore everything else. It should come as no great surprise that few people have confidence in your alleged expertise in this field. From 30 December 2009 ... Originally Posted by Tim Thompson Reference the book Magnetic Reconnection: MHD Theory and Applications by Eric Priest & Terry Forbes, Cambridge University Press, 2000. Magnetic reconnection is not induction. Here is the induction equation in a plasma as given in Priest & Forbes, page 5: $(1) \partial \boldsymbol B / \partial t = \nabla \times (\boldsymbol v \times \boldsymbol B) - \nabla \times (\eta \nabla \times \boldsymbol B)$ Here $\eta$ is the magnetic diffusivity. If $\eta$ is uniform then the induction equation reduces to ... $(2) \partial \boldsymbol B / \partial t = \nabla \times (\boldsymbol v \times \boldsymbol B) + \eta \nabla^2 \boldsymbol B$ { ... } The conversion of magnetic energy into a current always operates on a time-scale characteristic of the system, and that time scale is controlled by the ability of the magnetic field to move through the conductor, in order to create a dB/dt term from which the current is generated. That time-scale in a plasma is rather different than it is for a fixed conductor. Here we find the real deal once again in Priest & Forbes: "In space physics the distinction between ideal and non-ideal processes is important because simple estimates imply that magnetic dissipation acts on a time-scale which is many orders of magnitude slower than the observed time-scale of dynamic phenomena. For example, solar flares release stored magnetic energy in the corona within a period of 100 s. By comparison, the time-scale for magnetic dissipation based on a global scale length of 105 km is of the order of 106 yrs." Priest & Forbes, page 6 Induction is a motion of the magnetic field relative to the plasma as illustrated by the induction equation given above, which depends on the magnetic diffusivity of the plasma and is therefore limited to the diffusion timescale, and which cannot change the topology of the field. Magnetic reconnection is a change in the topology of the field and therefore cannot be induction in any way. And all of this was hashed out over two years ago, and here we are, right back to where we were then. I am right and you are dead wrong, just as wrong now as you were two years ago. Originally Posted by Michael Mozina Because it's NOT the "root cause" Tim. You're fundamentally relabeling an INDUCTION process 'reconnection". A simple coil in a car does the same thing Tim. It changes the field topology over time in the presence of a "conductor". Is that "magnetic reconnection" as well? To begin with, no the simple coil in a car does not change the topology of the magnetic field, it changes only the geometry, and it is therefore magnetic induction and certainly not magnetic reconnection. You could not tell the difference between a coil of wire and a plasma two years ago, and you still can't tell the difference ... Originally Posted by Tim Thompson Evidently, Mozina has never realized that a magnetized plasma and a coil of wire are not the same thing. So I will respond to Mozina's incredible ignorance of physics by quoting once again from Priest & Forbes, only this time with real physics, rather than the strange imitation of physics being promoted elsewhere. Given the equation I have labeled (2) above, we find ... "This is the basic equation of magnetic behavior in MHD, and it determines B once v is known. In the electromagnetic theory of fixed conductors, the electric field and electric current are primary variables with the current driven by electric fields. in such a fixed system the magnetic field is a secondary variable derived from the currents. However, in MHD the basic physics is quite different, since the plasma velocity (v) and magnetic field (B) are the primary variables, determined by the induction equation and the equation of motion, while the resulting current density (j) and electric field (E) are secondary and may be deduced from equations (1.8) and (1.10a) if required (Parker, 1996)." Priest & Forbes, page 14. So we come full circle? Two years ago you were ignorant about plasma physics. Today you are still ignorant of plasma physics. You can't use the basic words correctly, you have no clue to the basic physics, and cannot even tell the difference between a plasma and a coil of wire. So in conclusion, again from two years ago, ... Originally Posted by Tim Thompson This entire thread is just one constant repetition of the same tired old arguments: real physics vs. the pure prejudice of Mozina. It will never change because Mozina will never learn. So get used to zillions of pages to come with no change & no progress & no real physics ever from Mozina. That you can count on. And so my prophecy has come to pass. Zillions of pages and two years later we are right back where we started; no change, no progress, no real physics from Mozina, and Mozina, as predicted, never learned a thing. __________________ The point of philosophy is to start with something so simple as not to seem worth stating, and to end with something so paradoxical that no one will believe it. -- Bertrand Russell

The VERY FIRST EQUATION that they cite, (4.1), is based upon ohm's law and IDEAL MHD LIMITS! Furthermore the whole discussion is related to the PLASMA of the magnetosphere! You just shot your own argument in the foot. I think I need to really make this EXTREME SIMPLE for you to understand because you personally keep citing INAPPROPRIATE reference materials, in fact DAMNING references to your own case. In fact each of the last four references you have cited are *ALL* based upon *MHD THEORY*! The fact that the maths are based upon MHD theory LITERALLY DESTROYS YOUR ARGUMENT! Let's start by discussing the maths related to Magnetohydrodynamics. Quote: Magnetohydrodynamics (MHD) (magneto fluid dynamics or hydromagnetics) is an academic discipline which studies the dynamics of electrically conducting fluids. MHD is related to PARTICLES tusenfem, not VACUUMS that are DEVOID OF PARTICLES. Equivocation fallacy 1. You CANNOT USE MHD theories and maths to support your case T. The very fact that THOUSANDS of published works on RECONNECTION theory are all based on MHD theory SHOULD BE YOUR FIRST CLUE! Plasma, and the conductive and particle qualities of plasma, is NOT optional in the energy release process known as "reconnection/discharges". Clinger's empty vacuum experiences no INDUCED current. It experiences no ELECTRICAL DISCHARGE/CURRENT RECONNECTION. You folks are IGNORING the PHYSICS AND MATHS completely! Wake up and smell the coffee. Quote: And still if you don't understand in the simple case for the null to move to different values of A in Sweet's paper reconnection is a must then don't bother going to B&P. I guess the equivocation fallacy in play is the equivocation of magnetic flux change/time = "magnetic reconnection". This pretty much DESTROYS Clinger's claim (or need) for a NULL as some "special" place. It's not the "begging" or the "ending" of anything. It's just an evidently *UNNECESSARY* location in the first place. Sweet pretty much wrecked your argument from the start. He pointed out the REAL PHYSICAL DIFFERENCE between a non-conductive medium and a conductive one, namely the ability to INDUCE CURRENTS due to those flux changes.

Originally Posted by tusenfem NO, it is just because you don't understand electrodynamics, let alone plasma physics, that you discard any source about how magnetic fields work in a vacuum. Like Sweet, like Yamada et al., like Birn, etc. etc. Let's mention Dorelli et al. 2007 here. Ofcourse, because of the triviality of vacuum reconnection, nobody really looks at that, it first becomes interesting when plasma is present, however vacuum superpostition models are usually always the starting point for modeling. Quote: We investigate the global properties of magnetic reconnection at the dayside terrestrial magnetopause under generic northward interplanetary magnetic field (IMF) conditions. In particular, we consider a zero dipole tilt case where the y and z components of the IMF (in GSM coordinates) are equal in magnitude, using three-dimensional resistive magnetohydrodynamics (MHD) simulations to address the following questions: (1) What is the geometry of the dayside X line? (2) How is current density distributed over the magnetopause surface? The only way you can actually support your claim that reconnection occurs in the ABSENCE of all particles/plasma, is by coming up with *PUBLISHED* (not some guys website) maths related to the release of energy in "magnetic reconnection" *WITHOUT* MHD theory. Do you get that? You just yourself in the other foot too. It should be noted that you all do lip service to your love of math and physics. When confronted with the physics and the maths that destroy your case, you ignore them entirely. The fact that "reconnection" theory is based upon MHD theory DEMONSTRATES CONCLUSIVELY that plasma isn't optional, and "reconnection" can't occur in a "vacuum" devoid of all *PHYSICAL* particles.

You can't and won't own your own mistake and failure, such as your claim that electrical discharges cannot occur in conductors. That's your EPIC PHYSICS failure, not mine. Likewise, if you can't understand the horizon line color of a simple iron ion composite solar image after I've explained it to you several times, it's not my failure, it's your failure. Don't blame me for your epic failures in physics. Deny Dungey's claim that electrical discharges occur in flares and reconnection events all you like, but your Godfather of "reconnection" theory used both terms.

Are you making that claim? http://www.internationalskeptics.com...&postcount=370 This whole debate began when I offered what should have been a relatively simple definition of an "electrical discharge in cosmic plasma" that is congruent and "large scale" enough to apply to PLASMA COSMOLOGY THEORY AS A WHOLE. You're right of course that electrical discharges can occur with or without plasma. If however we are going to relate this all back to Dungey's original paper on "reconnection" theory related to solar activity, we'll have to introduce plasma (as he did).
