Geomagnetic Reversals and excursions: The origin of Earth's magnetic field - Bruce Buffett

[@bobleclair5665]

Maybe it’s the mantle that’s shifting,,when it comes to the Milankovitch cycles,,what leads the spin,what has more inertia,,the inner core +liquid or the mantle ? how does a dynamo flip polarity?

[@garyliu6589]

What generates earth magnetic field, is the earth core a permanent magnet or electromagnet? If it is an em, where does the electric current come from? How do we deduce there is an iron core or magnetic core inside the planet? From the energy balance point of view, there must be some energy input to enable earth rotation or earth inner core rotation. Where does the energy come from? Gravity or from the sun?

[@docr8197]

At 40:28 his diagram is very reminiscaent of solar flare activity ?? Anybody else see this aspect ??

[@rewtnode]

What about interactions with the sun‘s magnetic field, which flips every 11 years or so? Can the dynamics of a magnetic flip be influenced by the sun during a period when the earth’s magnetic field is meta stabile ?

[@mysteryneophyte]

Appears as if it's influenced by The large scale galactic current sheet. we travel through that zone every 12,500 years or so. Their is a ton of evidence that it influences our magneticfield, orbit, spin direction, vulcanism and plate tectonic disturbances and our core directly. It Sounds crazy huh? Specially if you arnt at all familiar with the evidence of these cyclical occurrences and the seemingly catastrophic implications. You should take a look into the subject.

i don't understand how the reply you received from REX MUNDI is relevant to your comment. i especially find it difficult to put much value in a reply from one who doesn't know the difference between there and their. this value is further diminished when i discover the lack of knowledge of how to contract are not as aren't. i would like to hear the perspective on this from someone who went to the degree of effort as that Maurice Cotterell has done to find an answer for this phenomenon. ✌️🐝➕️

The entire construction of this lecture is predicated on a belief, and not on an empirical fact. Mathematics are so easy to make pyramids of untruths with, and it is very seductive to allow the subconscious mind to be drawn into this fantasy especially as it tickles the vanities of both mathematicians, and theorists . May I suggest that there is at least one way to begin this sort of lecture, which will not drift into the unreal, or the theoretical, but will stay with feet firmly on the ground of the empirical, and practical , and not allow the lecturer to float off into vanities constructed out of the mere simulacrum of truth, and that is to conduct a definitive ,scalable, repeatable, experiment. We are assured by those who profess to know the truth, that at the centre of the earth, there are materials undefined, which are the cause of magnetism, which manifests itself as moving compasses on the surface of earth in certain manner. In simple terms, the compass points or directs us towards a " north" or "south" and all points between. We are told that the reason for this is that the earth has a magnetic field, which the compass needle follows, wherever it is located. Furthermore, it is said that the metallic elements contained at the core of this earth, are molten, or at very high temperature, which in itself causes some sceptics to argue that molten metallic elements can not set up a magnetic flux of any kind. If we were to take a gobbet of molten iron, and pour it into a hollow ceramic globe, which could be suspended from a filament and this could be spun at any speed whilst magnetic sensors were placed in situ that would detect a magnetic flux, then the proof would follow the experiment. Why is it that this has not been done under impartial observation, and repeated to prove the theory, which until proven can not be referred to as a fact. When fact proves a theory, then we can call the experiment successful, but until then, these ideas are nothing more than informed opinion, and the world is presently saturated with informed opinion, which is in many cases not worth wasting time listening to, but it is entertaining to witness the act of tapestry being woven, even if it is full of holes.

During the initial phases of the arrival of the full effects, communication with your chosen affiliates is going to be advantageous - crucial, as nothing can be completely planned/prepared for and you can bet that most things will have unexpected set backs and/or unexpected problems. Now presuming you're in a lucky location that is spared from the more devastating consequences, I'm wondering which modes of communication may still be temporarily feasible? Ie: Any Radio bands/frequencies expected to possibly hold up under the massively disrupted ionosphere?

@@CherishedChristianLife fuzz this is a YT site that has a tun of good information on the subject is he right 100% no but the most informed that I found . It's not guaranteed that it will be a disaster there apeers to be a thing called an excursion that the poles do from time to time that has no real effects I personally believe that they have traveled to far for it to be that we will know for sure in the next 4-5 years as to how drastic it may be . The magnetic north pole has just about a year ago past the geological north pole and is heading towards the Indian Ocean where the south pole is heading also . If we start seeing drastic problems in the crust then my suggestion is to locate the nearest cavern system in a set of old mountains not young ons they may not be stable and make your way there . Must be in mountains because the size of possible tidal waves could be stupendous we are talking flowing over cities like you step on ants and there is evidence of this type of activity in the past . So there's no reason to be worried about it if it happens have a plan you may survive you may not but there is absolutely nothing we can do to prevent it so no sense in worrying about it . This is why the fake global warming is pushed to keep us occupied and focused on something that they tell us we can do something about so that we don't panic. So don't panic it will do no good . Stay calm get informed make your best plan hope for the best and maybe it will be all for not .

Yes, minimal effect,but not as important as the solar wind forcing down on our mag field, and the suns magnetic fields forcing or entangling themselves to our magnetic field. The fact that this guy did not mention the Suns effect on the earth and other planets magnetic fields, as well as the effects of our galaxy's magnetic fields on our solar system, makes me doubt his premises.

I'm sorry, but there is no need for currents on the order of giga amps to produce geomagnetism. All you need to do is have moving electrical charges.

Earth's magnetosphere is a general relativistic phenomena. First; 2:43 good illustration showing that matter stratifies by density within a gravity well. From the our atmosphere to the center of the core. This is very important. it puts all the dense matter at the core, much of it iron, cobalt and gadolinium (ferromagnetic elements and also very dense) 3:30 "By virtue of the planet's rotation and the low viscosity, the kind of convetion you get has this sort of helical structure and I think we'll see... that this is an important ingredient for driving magnetic fields". Close, but the Earth's magnetosphere is a General Relativistic Phenomena: First, Matter stratisfies by density within a gravity well, the aurora does a good job of illustrating this stratification in our atmosphere, but it continues (by elemental density) all the way to the earth's center (or core) The greater percentage of the heaviest and densest elements will be found there. Much of it ferrous. Back to Einstein and general relativity. It comes down to time / acceleration and the understanding that the earth is a gravity WELL with its deepest point at the center and not some newtonian ball of equidense material that's weightless in the the middle. If we have 2 identical clocks, one in deep space (unaccelerated frame of reference) and one clock on the surface of the earth (9.8 m/s2 acceleration). The clock on the surface runs more slowly than the identical clock under no acceleration. Not many scientists would argue with that as we have done experiments to prove it out. However, if you place a third clock at the center of the earth, you would note that it ran MUCH slower than either of the other two clocks. Here, time is slowest and acceleration is at it's greatest. What this means is that for a planet like the earth that rotates (not tidally locked), the deeper you go from the surface into the core the slower the time will be and the greater the acceleration. What this translates to is a body who's core rotates faster in the direction of the planet's rotation. and this all takes place in spite of immense friction AND in the vacuum of space. It's more likely that it's a lot of spin (faster rates of rotation the closer you get to the center) but it's this dissimilar rotation of dense ferrous material due to general relativity that causes our electromagnetic field and certainly every magnetic field on a planet in our solar system including the sun.

[@joelstanley3894]

The earth acts as a electric motor, not a dynamo. The electric power doesn't start with the core, it just completes the circuit.

[@kohlundkamera9556]

minimum 2 things, that do not match the model: 1) Magnetism: if there would build up magnetic dipoles because of convection, there should be rejection as well as attraction, meaning, that if the typical flow of liquid ores is to the outside, most dipoles should point to the outside as well - but their end then must reject/repulse each other thus that the center would be hollow. The earth should be hollow! 2) Liquid core? How? The more you get further to the earths center, the higher is the weight/pressure on the whatever matter. Because liquid ores are lighter (less dense) than solid ones, the inner core must be solid if consisting of iron (remember: water is special, a exception, behaving reciprocal, it is liquid in its most dense state, while all other matter is solid in its densest state!!!). If the inner earth is liquid ore, the more dense and thus heavier crust must dive into the liquid core, the lighter molten/fluid iron should flow on the crust, on the tectonic plates and flood those, because it is lighter in weight - the plates should be buried under the liquid iron/ liquid ores!
