Instead of your crappy understanding of what MR is, perhaps you should link to a paper that shows what you are talking about?

Microwave imaging of quasi-periodic pulsations at flare current sheet Quote: The sun, an ordinary star closest to us, is a place where flares with QPPs appear frequently. In the standard flare model, magnetic reconnection plays an important role in releasing energy from the coronal magnetic field, ejecting plasmoid and accelerating electrons. After escaping from the reconnection region, those energetic electrons propagating along magnetic field lines will induce microwave emissions by a gyrosynchrotron mechanism. Thus, the temporal variation of microwave emissions is closely related to the process of electron acceleration. Once the magnetic reconnection happens quasi-periodically, the electron acceleration will also be quasi-periodic and QPPs will be generated. Poor jd116. Do you even know what a plasmoid is, jd116? I don’t. Except for Bosticks woo woo. Let’s find out together, ay? Seem important in the majority of space plasma’s. As the ELECTRIC UNIVERSE has stated. Best go read up on what a plasmoid is. __________________ “No rock. Any charge separation is limited. The electric field is pointing in the wrong direction.

Do you have an actual example? Or just theoretically on paper using incorrect assumptions? Magnetic fields DO NOT accelerate charged particles, electric fields do, always have always will. Quote: As well as mapping the magnetic structure of the Milky Way, the QUIJOTE data has also proved useful in other scenarios. The new data are also a unique tool for studying the anomalous microwave emission (AME), a type of emission first detected 25 years ago. AME is thought to be produced by the rotation of very small particles of dust in the interstellar medium, which tend to be oriented by the presence of the galactic magnetic field. A dusty plasma! Quote: "These new maps give a detailed description in a new frequency range, from 10 to 40 GHz, complementing those from space missions such as Planck and WMAP", comments José Alberto Rubiño, lead scientist of the QUIJOTE Collaboration. "We have characterized the synchrotron emission from our Galaxy with unprecedented accuracy. This radiation is the result of the emission by charged particles moving at velocities close to that of light within the Galactic magnetic field. These maps, the result of almost 9,000 hours of observation, are a unique tool for studying magnetism in the universe" he adds. Magnetism in an electric universe. What could cause this? Let’s read on... Quote: The maps from QUIJOTE have also permitted the study of the microwave emission from the center of our Galaxy. Recently an excess of microwave emission has been detected from this region, whose origin is unknown, but whose origin could be connected to the decay processes of dark matter particles The decay process from dark matter...

I guess there is no convincing you, but we already knew that. Fortunately, mainstream does know about magnetic field tension and the effects that it produces, such as bursty bulk flows (BBFs) in the Earth's magnetotail, and the oscillations of the more dipolar field lines close to Earth that are created by the BBF, and which can, again, be observed in the Earth's aurora. But don't let that bother you. And wow the only thing you take along from that phys.org blog is "dusty plasma" and "decay of dark matter". As we don't even know what dark matter is, you can easily delete that comment. It is most definitely NOT the mainstream "battery". Then again, YOU still have not explained to us what the Sun's battery is in EU. __________________ Scientific progress goes *BOINK* -- Calvin & Hobbes twitter: @tusenfem -- Super Duper Space Plasma Physicist

The thickness of such electron-dominated CSs may be as small as a few gyroradii of thermal electrons (Leonenko et al. 2021). Most of them are embedded in wider ion CSs, but single electron CSs can be observed too (Wang et al. 2018; Bandyopadhyay et al. 2021). Quote: Meanwhile, studying such CSs is especially important because simulations show that electron CSs most probably carry the largest electric currents in the solar wind (Podesta 2017b). Electron-to-ion Bulk Speed Ratio as a Parameter Reflecting the Occurrence So re-connecting currents layers. Quote: One may think that such objects have nothing to do with space weather and large-scale streams or flows that impact the terrestrial magnetosphere causing a chain of effects potentially dangerous for human be-ings and the technosphere. Meanwhile, recent observational studies show that CSs are intensively produced (i) in the turbulent region downstream of shocks, (ii) in corotating/stream interaction regions (CIRs/SIRs), and (ii) in magnetic cavities formed either by the HCS and an approaching high-speed stream/flow or by interact-ing SIRs and interplanetary coronal mass ejections (ICMEs). Such CSs are associated with so-called magnetic islands that represent 2-D sections of 3-D plasmoids/blobs/flux ropes originating from magnetic re-connection considerably intensified in turbulent plasmas and magnetic cavities compressed from at least one side (Khabarova et al. 2015, 2016; Khabarova & Zank, 2017; Adhikari et al. 2019; Malandraki et al. 2019). Figure 1a-c shows typical situations in which mag-netic cavities filled with CSs and magnetic islands can be formed, and Figure 1a-c illustrates distortion of the HCS that leads to confinement of CSs and magnetic islands.

Sympathetic Partial Filament Eruptions Caused by the Interaction between Two Nearby Filaments Citation Liping Yang et al 2023 ApJ 943 62 Quote: Abstract To better understand the physical connections in sympathetic solar eruptions, we investigated the interaction between two nearby filaments and their successive partial eruptions in the active region (AR) NOAA 12866 on 2021 September 9 by using data from the Solar Dynamics Observatory and the New Vacuum Solar Telescope. Based on Hα and extreme ultraviolet observations, we found that the right part of one filament (F1) became active first and experienced an obvious rolling motion. Then the whole body of the filament became wider and expanded toward another filament (F2). They collided with each other, and the interaction between them was accompanied by the brightening and bidirectional flows that appeared between them. This implies that magnetic reconnection occurred between the threads of two filaments. The interaction resulted in a rightward motion of F2 at first, and then its activation, and finally part of it erupted. Furthermore, when the erupted F2 deflected rapidly toward the middle part of F1, the left part of F1 erupted with its overlying magnetic fields pushed by F2. These observational results imply that these successive eruptions within a short time are physically linked, and this was caused by the interaction of the filaments. Nonlinear force-free field extrapolation reveals that the magnetic structure of the filament F1 was composed of several magnetic flux ropes with different twists. These results further advance our understanding of partial filament eruptions and sympathetic solar eruptions. Quote: Consequently, we conclude that the eruption of filaments involved in our study is likely to be sympathetic partial failed eruptions. Besides, the results from the NLFFF extrapolation demonstrated that both F1 and F2 have twisted magnetic structures, which are consistent with the observations that they manifested noticeable untwisting motions during their eruption processes. So....ELECTRIC CURRENTS as per Don Scott's paper. __________________ “No rock. Any charge separation is limited. The electric field is pointing in the wrong direction.

If you would go all the way back, you would find a description of how the currents are generated in the filaments .... by shear motion of the footpoints and possible rotation, again, magnetic field driving the current (tube in this case and not a sheet). __________________ Scientific progress goes *BOINK* -- Calvin & Hobbes twitter: @tusenfem -- Super Duper Space Plasma Physicist
