Speaking of "dishonest" and "ill informed", did you ever read Cosmic Plasma yet?
Unlike you, I and most other participants in this thread read and understood a freshman-level textbook on electromagnetism when we studied electromagnetism at university. That basic knowledge of electromagnetism is far more relevant to a discussion of magnetic reconnection than anything Alfvén or Peratt ever wrote.No Clinger, unlike you I actually read Cosmic Plasma. I actually read Peratt's book myself. I read and understood Alfven's double layer paper that puts more nails in the coffin of the "pseudoscience" called "magnetic reconnection" in any current carrying environment.
It's been almost 40 years since I took freshman-level courses in physics. Most of the physics books I read these days are research monographs or were written for upper division or graduate courses. I don't recall reading the highlighted statement in Purcell's Electricity and Magnetism, but I can assure you Purcell mentions ∇∙B=0 and explains what it means.You haven't read Alfven's book *AT ALL*, EVER! I don't know how long ago you actually read a freshman book on physics, but they all mention that magnetic lines have no beginning and no ending.
It does not mean what you think it means. You think it means there can be no magnetic reconnection. As sol invictus told you quite plainly, you're wrong about that.
You're the only person here who's confusing inductance with reconnection.They all mention that INDUCTANCE is called INDUCTANCE, not "reconnection" too.
You're the one who continues to demonstrate ignorance of the difference between ∇∙B and ∂B/∂t.I've already "admitted" that "FIELD ALIGNED CURRENTS" can and do change their topology over time. You're the one insisting that a line without a beginning or an ending somehow "reconnects".
You're shouting because you don't know and refuse to acknowledge the distinction between inductance and a units-specific magnetic constant.I was talking about your LAST line that is in fact BASIC INDUCTANCE, as were all the permeability variables related to a "vacuum".
Many people have tried to teach you rudiments of electromagnetism. All have failed. Why should I be different?You personally have absolutely nothing to teach me about electromagnetism.
No. What's extremely clear is that you don't understand the meaning of ∇∙B=0.It's extremely clear that you're completely ignoring the prime directives of magnetic field lines and their INABILITY to begin or end.
I actually sketched a proof that Gauss's law for magnetism holds throughout the experiment I've been suggesting to you for most of the past year. When you so ignorantly claimed that my proof demonstrates "inductance", I showed you most of the relevant calculation, leaving only a couple of easy steps for you to complete yourself. You ignored that calculation, probably because you are as ignorant of math as you are of electromagnetism.
No.It's clear you're confusing INDUCTANCE per unit length with "reconnections" per unit length.
That's one of the stupidest accusations you've ever made, despite plenty of competition. For example:
Until you understand the concept of a magnetic field, you won't understand how magnetic fields interact with charged particles in motion. Until you understand that the topology of magnetic fields can change over time, as in the experiment I've been suggesting, you won't be able to understand how magnetic fields can interact with plasma.You don't care one iota about KINETIC ENERGY and PARTICLES either.
Yet your irony meters explode whenever you say such things.You and RC are in fact arguing from pure arrogant ignorance, and you've both been doing it for MONTHS if not YEARS now.
If you had anything that actually "destroyed" Alfven's claim that MR theory is pure "pseudoscience", and irrelevant in current carrying plasma, you would have provided it by now.
Dungey did that in 1953:
That's from the introduction toYamada et al said:Dungey (1953) showed that such a current sheet can indeed be formed by the collapse of the magnetic field near an X-type neutral point as shown in Fig. 3 and suggested that lines of force can be broken and rejoined in the current sheet. This sheet is called a neutral sheet or diffusion region. When the field lines are reconnected, the topology of magnetic configuration changes and j×B forces result in the conversion of magnetic energy to kinetic energy.
Masaaki Yamada, Russell Kulsrud, and Hantao Ji. Magnetic reconnection. Reviews of Modern Physics, volume 82, January-March 2010, pages 603-664.
Their Figure 3 is essentially Dungey's Figure 1 from the 1958 paper you've been citing incessantly. The experiment I've been suggesting reproduces the magnetic fields shown in both of Dungey's figures, and also reproduces the magnetic fields shown in Wikipedia's animation of magnetic reconnection.
Without your ample stockpile of "pure, blind, arrogant ignorance", you couldn't continue your pure, blind, arrogant denial of those facts.
