if earth center is 1000's of grades hot and the magnetism in iron is lost when reaches 600 +/- ºC, from where come from the earth magnetism??
oh, no!!! from big hematite or other magnetic magnetic rocks deposit??? :-D

pneumatician, have you ever considered that your theories are just too radical and visionary for plodders like us?
There must be better places for discussing these things, and better people to discuss them with.
How do you think Einstein felt as a young man trying to discuss his theories with ordinary physicists?
Many of them probably reacted with extreme skepticism, even derision.
Maybe you should try to find people more willing and able to accept your theories.
People more ready to accept that the mainstream of science is not the be all and end all.
You could have profitable discussions with people like that.
They could learn from you, and you could learn from them.
There seem to be few people like that around here, but they must be out there.
Find them, and they may be able to help your theories come to fruition.

of course, the problem is: not my own theories, only reality, if people here do not want to search truth ignore my messages. I don't want to talk with
any person in particular, I are only searching for what reason if iron lost magnetism at 600 ºC */- and the earth core, according to official
science, say is at thousands of degrees from where come from the earth magnetism??? Do not lost your time with paternalism, I read others boards, web
pages, podcast... and nobody has an answer, do you have it? for your peace of mind, places like this normally are last place where I ask.
Also for your information I have some more questions but, I think, maybe can cause brain malfuntions in many guys so I are prudent and I don't ask
them :-)
I'm not asking for malice or trolling people, it's just to find out if anyone here has a new theory, call me romantic.
It's a question that makes you look at it if every time that someone asks anything out of your mental corpus makes you nervous.

Somewhere in the internet you will find videos of a research group that has been spinning a large ball of liquid sodium or NaK or mercury - I forget
anyway the result is that magnetic fields are generated by hot spinning non-ferromagnetic, but electrically conductive fluids.
The ball does exist within the Earth's magnetic field so that may be involved,
just as the Earth spinning in the magnetic field of the Sun
and possibly the Sun in the field(s) of the galaxy ... universe ...
or it may be irrelevant.
Whatever the physics is, it demonstrably works.

Son, you're not nearly as clever as you think you are. Did you even check with Wikipedia? It's all there.
Short story: Yes, iron looses it's permanent magnetic properties above the Curie-temperature (770C for pure iron). However, the earths magnetic field
is generated by induction. And this still works above the Curie-temperature.

The mechanism generating the magnetic field has been described as a self excited dynamo. Like the dynamos in old cars, the field coils where driven by
the output. Similar to alternators in most present day cars.
Below is diagram of a Bullard's disk dynamo from https://www.researchgate.net/publication/226464525_The_Riga_...
What I have wondered is how could this be arranged in a container of liquid metal with a rotating impeller and stationary baffles.
PS: I have now read part of the paper above. Below is an interesting part of it.
"Leaving aside the specific technical realization, the general question of magnetic field self-excitation is how is it possible for the electric
current (Equation (1))
which is generated by the magnetic field also to produce the very same magnetic
field. The simplest illustration of such a bootstrap effect is given by the homopolar
disk dynamo (Figure 1), basically consisting of a rotating metal disk which is
slidingly connected to a wire wound around the rotation axis of the disk (Bullard, 1955). This simple device can work as a self-excited dynamo if the
angular
velocity ω of the disk exceeds a certain critical value ωc = 2πR/L, with R and
L denoting the Ohmic resistance of the circuit and the mutual inductance between
the circuit and the rim of the disk, respectively. Although this device looks very
simple, one should note the presence of insulating spacings between the conducting
parts forcing the current in the desired direction. In contrast to multiply connected
and asymmetric technical dynamos of this sort, cosmic dynamos work in singly
connected domains with uniform conductivity.
It was after the strong magnetic field in sunspots had been detected by Hale
in 1908 that Larmor (1919) suggested self-excitation as the source of magnetic
fields of large astronomical bodies, such as the Sun. Later, the dynamo process was
adopted as an explanation of the geomagnetic field, too. Early contributions to dynamo theory based on the equations of magnetohydrodynamics (MHD)
were made
by Elsasser (1946) and Bullard (1949). Since then, much analytical and numerical
progress has been made in the understanding of homogeneous dynamo"

No. The laws of thermodynamics still apply. You simply cannot pull energy out of nothing.

Yes Fulman is correct.
The detail is: dynamos convert rotational energy into electrical energy. So the energy to drive the current through the one turn field coil of the
Bullard's disk dynamo comes from the the energy required to rotate the disc. The magnetic field created by the current flowing in the disc interacts
with the magnetic field of the one turn field coil to generate a torque. Thanks to Lenz's law that torque opposes the rotation of the disc. As always
no free energy, no perpetual motion machines.
See wiki for the details of Lenz's law.

And what causes it to go from the lower energy level to the higher energy level in the first place? Is it not by heat, collisions (cause by an
increase in heat?) or excitation by exisitng photons? |
From just an average joe with an interest in chemistry I believe it has to do with the correct UV (?measurement?) contacting the atom=reach different
excited states/energy levels. Too high/low would pass right through.? Keep in mind I have <year Tech. edu level. Just like to learn.

how was that?, the easiest explanation is the most plausible?

Your posts remind me of that old Star Trek episode where the alien woman is yelling, "Brain! Brain! Brain! What means brain!?!"
Are you honestly suggesting that there is a miniature sun inside the earth, and that this is the easiest explanation for anything?

Damn I can't believe I forgot this sht.. But what's the equivalent for the other way around? Electron from lower orbital to higher?
And even though this is quoting a guy from 12 years ago, does anyone know if Sedit an expert at this? This can't be the only method?

The other way around would be excitation, which can be done thermally as well as through absorption of photos.
That's how you get emission spectra, but you can also get electromagnetic radiation by blackbody radiation, and nuclear decay (although that generally
gives off gammas and X-rays).

exist many other theories, nobody can prove the official shit so any other theorie have the equal value no matter from who come from if from a sacred
cow or a illiterate as long as it sounds consistent, logical, and reasonable. if you do not want or can accept them is your problem.

I think that's a nice way of avoiding the use of the word bullshit unlike the OP.
Here are some interesting facts: There are several hot springs in Britain for example 45°C in Bath but its about 50 million years since there was any
volcanic activity in Britain. Wow 50 million years have past and the presumably once molten rock that was near the surface of Bath can still heat
spring water to 45°C.
Below is paper that describes the geology that creates the hot springs:

i can come up with an infinite amount of different theories about every natural phenomenon, that doesn't mean they are valid.
science by itself works on approximations, every theory we have isn't the real truth, but something that gets close to it more than other theories.
you are totally free to come up with different theories, but a theory to be valid has to give a better explanation than the current accepted theory,
and it has to predict a behaviour that the current theory can't explain.
why do you think that we are looking for a relativistic quantum theory? because quantum mechanics works well at the quantum scale, while relativity
works well at huge scales, when you have relativistic events with quantum scales like black holes, ahhh everything breaks, that's a clear sign we are
missing something.

this just sounds like stuff you pulled from your ass, to get even a speck of credibility you have to expand your argument and give solid statements,
otherwise i could do the same:
or no!!! but yes, FIRE ELEMENTALS :-) science hasn't disproven spirits so that clearly is the solution, they gather energy from the Immaterium
Dimension and try to melt their way out of the earth core, that's why volcanoes erupt.
sounds the same to me
