Yes I said that.
Yes except the core has plastic like qualities so it movement is more complex.
No doubt. Fluid dynamics. But it follows Faraday’s Laws. Moving charges create a mag field and a changing field causes charge flow. What about all of the beta particles flying off the Sun? - re moving charges. That should be added to the Suns mag field. Those particles hit the Earths atmosphere.
yes they do!
More then just Beta particles off the sun, thermonuclear processes so energetic heavy particles!
The atmosphere shields but not completely, the earth’s magnetic field re-directs charged particles (beta, proton, etc.), of course how much defection depends on their energy. Also there earth’s field is not static but dynamic, strengthens and weakness even goes to zero & flips polarity. (There is evidence that is now happening!) Also the field is not simple, earth’s field is not like a simple bar magnet there are other components project another field in a different direction much weaker but there.
As you said fluid dynamics governs the core, but not a true fluid has plastic qualities, also has internal currents, dynamics magnetic field therefore its electromagnetic fluid dynamics or MHD - magnetohydrodynamics. All very very non-linear mathematics very hard to understand it well.
Yet it all works for us and makes life possible on the earth.
Very true, the field changes but very infrequently relative to human existence. And when it changes, dramatic things happen on Earth.
Sorry if I am repeating myself here...
I am suggesting here that, as with Sun photon radiation which affects (heats the Earth and interacts with the atmosphere), so does the Sun’s mag field interact with Earths. And the Sun mag field is many times that of Earths. I am even suggesting that the Suns mag field induces the Earth’s mag field (maybe cancels it out if it is self induced).
Hey, there is a thought — does the Sun’s mag field affect the Earth’s orbit (in additional to gravity) and might the earth’s orbit radius shrink or expand based on this attraction. However, if the Earth’s mag field is a result of the Sun’s mag field, then equilibrium is reached. And, if the Earth’s mag field is independent of the Sun then the two bodies can attract or repel. I am guessing that the former is true. :)
“...I am even suggesting that the Suns mag field induces the Earth’s mag field (maybe cancels it out if it is self induced). ....”
The dynamics of the core gives the earth its field, the sun’s field contributes to the overall ambient field on the earth. If it induces a magnetic field here, given the tremendous difference in field strengths of the two fields any additional induced field would be so small as to be very difficult to measure. At least to my understanding, could be wrong.
Exactly. Suspect that the Earth’s mag field is very small in comparison to the Sun’s.
I heard or read recently that the Earths orbit is changing... and that might be the cause of “Global Warming.”
Maybe the mutual attraction “force” variable due to the H/B field is changing with the Sun’s mag field strength.
An interesting topic for a thesis. :)
Find a school & 3 to 5 advisors and go write it!
I am too old. :) But fun discussing it with you — thank you! Sounds like you have some background in this area.
I actually have a MS in astrophysics, never used it in a anything astrophysical. Now I am semi-retired living in a university town now. (PhD in engineering.) I might go sit in on some physics classes, depends on what wife tells me what my free time is.
reminded me to add this new link to my list.

Sitting in Physic classes sounds like fun. Not fun back when I was in college, though. The freshman and sophomore classes slam the students with information and it can be overwhelming.
What specialty in Engineering?
Actually it was Engineering Physics that way I could use a lot of my grad physics course the specialty was Electrical engineering. My thing was signal processing & pattern recognition.
Cool. Are you retired?
Me? EE — Power. But I took all of the Physics classes, through Modern Physics, Thermal, and even a Astro Physics.
I struggled with it as a Freshman but it eventually caught on and enjoyed it a lot.
“...Cool. Are you retired?...”
I view myself as retired though I have been giving time (too much!) to a small local company acting as their CTO. I am not doing this too much longer, no more then 2 moore years if that. Grandkids are starting to get interesting becoming more then eating pooping/peeing crying machines.
I like to think that I inspired him to become an EE. He has gone a lot farther than me, he is doing really well, and likes RF a lot. He'll probably end up in RF.
Me? I'll probably continue working until I die. :)
