I have already proved it.The science claim for the solid inner iron core at the Earth dynamo:https://www.scientificamerican.com/article/earths-inner-core-may-have-an-inner-core/"Earth's core consists of a solid iron-nickel ball rotating within a layer of liquid metal."
So far you and BC have totally failed to offer even a single article to support the imagination of none solid inner core in a dynamo.
Hence, based on their understanding the inner core has a solid dipole tangent cylinder shape.
https://en.wikipedia.org/wiki/Earth%27s_inner_core"Earth's inner core is the innermost geologic layer of planet Earth. It is primarily a solid ball with a radius of about 1,220 km (760 mi), which is about 20% of Earth's radius or 70% of the Moon's radius.[1][2]The temperature at the inner core's surface is estimated to be approximately 5,700 K"Do you need some more citations?If so, please read the following:https://www.universetoday.com/160317/the-earth-has-an-even-more-inner-core-and-its-a-ball-of-solid-metal/"In a paper that appeared in Nature Communications, the team reports finding evidence for another distinct layer (a solid metal ball) in the center of Earth?s inner core"Do you think that when this team reports finding evidence for a solid metal ball in the center of Earth?s inner core, they just lie to all of us?It is not assumption or simulation. They claim for - Evidence.
Thanks for that great article.It is stated:https://websites.pmc.ucsc.edu/~glatz/geodynamo.html"It has long been speculated that this mechanism is a convective dynamo operating in the Earth's fluid outer core, which surrounds its solid inner core, both being mainly composed of iron. The solid inner core is roughly the size of the moon but at the temperature of the surface of the sun."Hence, even in this article they discuss about solid inner core within spherical shell of the outer fluid core."Large zonal? exist on an imaginary "tangent cylinder" due to the effects of large rotation, small fluid viscosity, and the presence of the solid inner core within spherical shell of the outer fluid core.
Are you sure that we discuss about fair chance?
Why all of those clear messages including the "evidence" which proves that the inner core must be solid aren't good enough for you?

The quote that you have provided states that there is a solid core within the layer of liquid metal. What your quote does not say is that the solid core is an essential part of the dynamo. Therefore, this quote does not meet my requirement.
Last I checked, the fluid outer core is where the geodynamo is located, not the solid inner core: https://websites.pmc.ucsc.edu/~glatz/geodynamo.html
Yes, it states that the inner core is solid. We already knew that. That isn't what we are debating here. What we are debating is whether a solid core is needed for there to be a dynamo.
Yes. Three chances to cite a proper source is plenty fair.
I'm not asking for evidence that the inner core is solid. Again, we already knew that. What I'm asking for is a quote from a reputable scientific source that a solid core is necessary in order for a dynamo to generate a magnetic field (which is relevant because the Sun doesn't have a solid core despite having a dynamo).
Provide us with a quote from a reputable scientific source that a solid core is absolutely necessary in order for a dynamo to generate a magnetic field.
Do you care about keeping your thread open, Dave?
This is your last chance.
Conclusion:
Take out the solid core from the Sun
Yes, the Solid inner core is essential part of the dynamo!Without it, there is no dynamo.
It is stated:https://websites.pmc.ucsc.edu/~glatz/geodynamo.html"Large zonal exist on an imaginary "tangent cylinder" due to the effects of large rotation, small fluid viscosity, and the presence of the solid inner core within spherical shell of the outer fluid core.
Hence, It is expected that in any Geodynamo there must be a solid inner core within spherical shell of outer fluid core.
Well, it was already explained in the following video clip (offered by BC) that the fluid outer core is where the Electromagnetic is generated.https://www.thenakedscientists.com/forum/index.php?topic=86392.msg708000#msg708000At 1:33 - The magnetic fields is created at the outer sphere.
Yes, it is a mandatory request!In any real Geodynamo there must be a solid inner core within spherical shell of the outer fluid core, while the magnetic fields is created at the outer sphere.So simple and clear.
Sorry, till this moment, you all didn't cite even one single article to support the imagination of geodynamo that can work properly without solid inner core!
Sorry, you have a severe mistake with regards the Sun.Take out the solid core from the Sun, and it would stop immediately to generate its magnetic fields.Therefore, the sun MUST have solid inner core for its ability to generate magnetic fields!
Please provide one real article (ONLY ONE) where it is explained how a geodynamo can generate magnetic fields without solid inner core.
Do you care about real science?
You all have totally failed to show that a geodynamo can work without solid inner core and you refuse to accept the clear explanation from all the articles which you have offered so far.
The fusion activity could increase the heat at the core to over than 10^7k.
At that temp, nothing could be solid.
Even the vertical tidal force won't help the sun to regain its solid inner core.Therefore, just in order to support the fusion imagination, you hope that somehow the Sun can generate magnetic fields without a solid inner core.
A magnetic field is produced whenever an electrical charge is in motion.
Plasma is then a collection of the various charged particles that are free to move in response to fields they generate or fields that are applied to the collection and, on the average, is almost electrically neutral.
Magnetic fields are generated by the convective motions of conducting materials: plasma in most of the universe and conducting liquids in the case of planetary objects.
This is because the Sun?s surface isn't solid like Earth's. Instead, the Sun is made of super-hot, electrically charged gas called plasma.
Unfortunately, it seems that I would continue to accept the explanation which had been given by all the articles (which fully support a solid inner core), while you wouldn't accept the explanation by those articles as it would kill the idea of fusion activity at the Sun.
There is no need to argue on something that is so clear in all the articles.
As the master of this forum, you have the freedom to ignore the articles and decide that Geodynamo should work without solid inner core and close the thread.
