Are you willing to be educated ?

It's entirely possible that after reading Dungey's paper or Paratt's quote, or any of the other references that I've provided that you'll come to understand and accept the fact that electrical discharges can and do occur in plasmas.
That *SINGLE* revelation/piece of knowledge would put you way ahead of every EU hater in this thread.
Of course! How else can the magnetic lines change their topology, if lines are not broken and reconnected? However, whether reconnection is a "feature of attraction and repulsion" -- as you phrase it -- or whether it is a simultaneous event not involved in the forces -- I'll allow the physicists answer that. Clearly both attraction/repulsion occur while lines are breaking and reconnecting.
I have not dodged this question; it simply makes no sense. It seems to me to be a naive way of looking at this. I cannot imagine other than reconnecting happens as soon as there is any movement, even if it is on a microscopic level. You seem to be implying that attraction happens and then reconnection happens at different times, which makes no sense. As I said above, clearly both attraction/repulsion occur while lines are breaking and reconnecting.
Are you willing to be educated ?
1) Explain to me how you can have electrical discharge without electrons.
2) What does it have to do with me ?
"Hater" ? What does that mean ?
J W Dungey's 1958 paper (to which Michael Mozina refers almost daily) contains even clearer examples of magnetic reconnection in the B field.
I can't believe your still trying to use DUNGEY to support your claims.
...
Do you have the mathematical formulas that were used to create those images you've posted? AFAIK, they are simple "cartoon-like depictions'' (not real in any way) of what actually happens to the magnetic lines. If those images do happen to be created mathematically (which I doubt), the formulas themselves should resolve the issue. Do you have them? Do you have ANY background information on those cartoons/images?
PS,
If I understand your argument correctly, you're associating a "topology change in the magnetic lines of attraction (and repulsion?) between the two magnetic fields" with "magnetic reconnection". Do I properly understand your argument? Are you including or excluding the lines of repulsion in terms of "flux" and/or "reconnection"?
When we go from: [N<<<<<<<S][N<<<<<<<S]
to: [N<<<<<<<S] ................................................. [N<<<<<<<<S]
if you accept ∇∙B = 0, every time magnetic lines break they must instantaneously reconnect. What more is there to say?
The mathematical formulas that were the basis of the actions in those animations must start with this fundamantal law of physics.
What? Magnetic lines are magnetic lines; there is no distinction between those of flux, repulsion/attraction, reconnection, etc. The only difference I can discern (from your abuse of these terms) is that in reconnection and when in flux, the magnetic lines are moving, whereas in repulsion/attraction they may or may not be moving.
James Dungey, whose name is generally not shouted by legitimate scientists by the way, was one of the pioneers in assembling the theories of magnetic reconnection as it applies to activity in the solar atmosphere.
Either Dungey can be used as a reference here,.....
(Whether they withdraw or merge depends on whether you reduce or increase the current in the rods.
FYI PS,
I can't for the life of me figure out how you decided if an individual line actually "broke" somewhere away from the magnets and "reconnected" to a different broken field line away from the magnets. For all I can tell from your simple cartoon, the lines simply form, stretch, dissipate over distance, and new B lines form between the magnets to compensate for the movement. I have no evidence from your simple cartoon that any lines were actually "broken" in space or "reconnected" to other individual lines.
Look, the animations are not presented as evidence. They are illustrations intended to focus the mind on the processes going on. Using Humanzee's two still pictures from that animation, how can any lines dissipate as they evolve from the first into the second picture?

Look, I'm not using this cartoon/illustration as "evidence", but how can Yosemite Sam take those cannonballs to the face and that not be a real physics demonstration that cannonballs to the face are not lethal?![]()
Using Humanzee's two still pictures from that animation, how can any lines dissipate as they evolve from the first into the second picture? Can you posit any way that ∇∙B = 0 can be maintained when a line breaks if it does not instantaneously reconnect as shown below?
The only way I know that magnetic lines can dissipate is if a current supporting it decreases. There are no currents here to decrease, since the magnetism is due to the intrinsic properties of the magnets. How can a magnetic line from a bar magnet dissipate?
This is the kind of adolescent debating that makes you so infamous as a nuisance and a fraud. You made no effort to address the substance of my comment while taking my use of an illustration out of context. Do you have any genuine interest in this subject or are you just here to gain pleasure from your obfuscating? My patience is running thin. Do you have any serious response to my comment (repeated below) or are you admitting magnetic reconnection is a real process?
I initially posed a question involving two bar magnets to gain an understanding of what is meant in this thread by magnetic reconnection. I used a simple diagram to pose my question. Then, I found the animation in question and posted it because it provided a good image for my question. My question was (and still is): The magnetic fields of two separate magnets has a different topology than when they are combined. How can the these two different topological shapes come about if magnetic lines do not break and reconnect? Perhaps, if you have not studied topology, you do not understand the significance of this point -- is that the problem?Oy Vey! You're trying to use SOME RANDOM IMAGE YOU FOUND ON THE INTERNET to make your *ENTIRE* case PS! No published paper comes with it. No math comes with it. Nothing at ALL comes with it. It's just a CARTOON for all I know! Talk about BLATANT FRAUD!
You never even responded to the paper I offered you to EXPLAIN that process.
OK, that's fine. There is nothing wrong with not understanding. Obviously, you do not know why or how the magnetic fields topologically change when bar magnets are brought together and then pulled apart. That is really the end of this discussion. Others here have made it clear that the process comes about through magnetic reconnection. Thanks for playing.As best as I can tell, the lines FORM, stretch, change shape and eventually new lines take the place of old lines and old lines simply "fade away". I really can't tell ANYTHING about what occurs between two CARTOON/ILLUSTRATION images PS. It's not even rational to ask me to "explain" some random image you found on the internet without a SHRED of background information about the image.
I have no idea why you think my opinions about the above have any value, but I'll do my best even though I am not a plasma physicist and I know very little about electrical discharges and plasmas.It seems to me that what you're describing PS amounts to nothing more than "changing magnetic fields over time". Add a conductor like plasma to the mix and like Somov suggests, an E field will be INDUCED between the magnets. So what? Do you agree with Somov that an E field will be induced at that X point? Do you agree with Dungey that induced E field will eventually result in an "electrical discharge" in plasma?
Don't dodge my direct questions this time. Answer them.
Yes, and he explained as Somov explained that an E field was INDUCED at that X point and an ELECTRICAL DISCHARGE occurs as a result.
Mozina, read this carefully so you understand my position here:

We also have Gauss (∇∙B = 0), which makes it impossible for magnetic lines to break without simultaneously reconnecting.
You're right, I'm sorry, I should have explained. The relevance is that it addresses those magnetic field topology changes you're worried about. The topology changes will induce an E field in plasma. Nothing much is going to happen in a vacuum in terms of a release of energy, and Clinger's experiment is DOOMED because he's trying to change dB/dt "slowly" and nothing much is going to happen. He doesn't have a single electron to his name to work with, so I have no idea how he expects to release energy from that contraption yet. All I know so far is that he's painting himself into an energy corner in terms of kinetic energy and it's nothing like the electrical discharge process Dungey describes.The paper you "offered" had nothing to do with bar magnets and you "offered" no accompanying comments to reveal its relevance.

I can say that if a conductor is introduced in a changing magnetic field a current will be induced.
Whether that current is a discharge (if the conductor is a plasma -- based on previous discussions here) seems to be a matter of semantics.
