Gauss's Law and Magnetic Reconnection

AI Thread Summary
Gauss's law for magnetism, which states that the divergence of the magnetic field (Div B = 0) allows for magnetic field lines to terminate at neutral points, does not contradict the phenomenon of magnetic reconnection. Magnetic reconnection is linked to the acceleration processes that create aurora borealis, as noted by the THEMIS project. The discussion emphasizes the importance of understanding the relationship between Gauss's law and magnetic reconnection in the context of electromagnetic theory. Participants encourage further exploration of existing resources for deeper insights. Overall, the conversation highlights the interconnectedness of magnetic laws and natural phenomena like auroras.

Hi, I have a question regarding Gauss's law and magnetic reconnection. From what I have heard Gauss's law for magnetism (Div B = 0) clearly states that magnetic reconnection cannot occur. Furthermore, according to the THEMIS project, magnetic reconnection triggers an acceleration that creates aurora borealis.

My question is in regard to what contradictions there are between Gauss's law and magnetic reconnection. I appreciate any help given.

Best regards//

NONE.

Gauss' law for magnetism (divB = 0) allows field lines to end at neutral points.

There's plenty of stuff on this on the internet, eg wikipedia and http://www.cesura17.net/~will/Ephemera/Nerdliness/MR/index.html
 
Thanks for answering, but how can I relate Gauss's law for magnetism to aurora borealis. The reason I emphasized Gauss's law for magnetism is due to the fact that I read about aurora borealis and stumbled upon magnetic reconnection and from there arrived at the lovely train of Maxwell's equations; Gauss's law for magnetism.

are you trolling? :frown:

there are plenty of websites where your can look this up, several of which you've obviously already seen

read some more, and if there's anything that needs further explanation, link to it and ask for comment
 
I see, it seems as I have already stumbled upon the answer. I just had to read between the lines. If there is anything else, I will not hesitate to ask. Much obliged sir.

Thread 'Venus and Jupiter Conjunction'

Today at about 4:30 am I saw the conjunction of Venus and Jupiter, where they were about the width of the full moon, or one half degree apart. Did anyone else see it? Edit: The moon is 2,200 miles in diameter and at a distance of 240,000 miles. Thereby it subtends an angle in radians of 2,200/240,000=.01 (approximately). With pi radians being 180 degrees, one radian is 57.3 degrees, so that .01 radians is about .50 degrees (angle subtended by the moon). (.57 to be more exact, but with...
