Lightning connected with the magnetism of Earth core?

I know this is not directly related, but while I'm here I may as well clear up another apparent misunderstanding for the OP.

The Earth's core is not magnetized. The Earth's magnetic field is generated by the swirling around of liquid in the outer core (driven by thermal and, more importantly, compositional convection) in what is known as the geodynamo.

In 1819 Hans Christian Oersted observed that a wire carrying a current could deflect a compass needle, this implied that a current in a wire produces a magnetic field. It was later realized that the magnetism in a material could be explained by considering moving electrical charges on an atomic level.

Ferromagnetism: This is a special case whereby the atomic neighbourhood allows for spontaneous magnetization. In this case, the atomic moments are aligned parallel; few materials are ferromagnetic at temperatures above 0°C, some of which include: iron, nickel, cobalt, gadolinium, and chromium dioxide. In a material such as a rock, small groups of perfectly aligned atoms may exist in a spatial configuration; one of these zones is called a magnetic domain, and has a typical diameter of a few μm, these contribute to the magnetism of a material at a macroscopic scale.


In a ferromagnetic substance the alignment of atoms depends on a balance between thermal and chemical bonding energy. The chemical bonding energy acts to align the magnetic moments of the atoms, whereas the thermal energy causes the atoms to vibrate out of line. At temperatures below the Curie temperature the bonding energy prevails and the atoms are locked into a formation which enables spontaneous magnetization. At temperatures above the Curie temperature thermal agitation destroys existing magnetic domains such that the material loses its magnetization.

As pressure is increased the Curie temperature lowers; thus at the core where temperature and pressure are very high relative to the conditions at the surface, we would expect a material to be below its Curie point such that it is not magnetic.

This is a wonderful report. Well done.

A little problem, though. You describe ferromagnetism beautifully. You describe paramagnetism beautifully. While it is absolutely true that the magnetohydrodynamic fluids comprising the mantle and core materials in compositional convection are not ferromagnetic, this does not mean that they are not magnetized. It means only that they are not ferromagnetically magnetized. They are paramagnetically magnetized.

The important question now is how?

I know how but it is inappropriate to post it on this public forum. Richard Feynman and Murray Gell/Mann solved the problem in 1957 and it is related to the quest for detecting geoneutrinos. Have you read Learned's recent paper?

Thank you for your most useful post. It helped me immensely.

Guys, this argument is most unseemly. The process of geomagnetism is distinct from the process of helio- -- or I prefer "steleo-" -- magnetism. Geomagnetism is driven by a much different process than steleomagnetism. Steleomagnetism is plasmatically electromagentic in nature. The Jovian magnetospheres are quasisteleomagnetic in nature more akin to the Sun's process, yet far less efficiently -- or efficaceously.

Geomagnetism is an affect of magnetohydrodynamics, which is a distinct process from plasmatically-driven steleomagnetism. Billiards described it correctly and beautifully.

How magnetohydrodynamics actually works is in much heated debate. Though, I do have a strong hypothesis as to how it actually works. It's related to a collaboration between Richard Feynamn and Murray Gell-Mann in 1957.

OH. BTW, lighning is very simple to explain.

Severe storm systems most often travel with the prevailing tropospheric winds at right angles to the Earth's geomagnetospheric field lines.

The elementary electromagnetic/magnetoelectric classic binary tells us that any conductor with potential electric current flow can be induced to conduct an electric current by passing it at right angles to a magnetic field.

That's exactly what's happening when servere storms produce lightning.

Simple, right?

Simple enough, however it does not explain why the larger materia forms the negative charge below the lighter forming the positive. It suggests that lightning has a direction, something like the Earth's core is guiding it.

Why wouldn't lightning be discharged out into outer space rather than towards the ground? it woud actualy make more sense if lightning sought itself towards outer space rather than back unto the ground. Ofcoarse this is all speculation, but it would seem the Earth cores revolvement in speed and direction guides lightning in both direction and intensity. If one would calculate some kindoff pattern between these two, then it would be possible to calculate what speed and direction the eartch core is currently revolving.

it seems Earth's core generates the magnetism causing the discharge motion to be downwards rather than upwards, this would also suggest there is a intimate coaperation between the two.

This was the case until the NASA Space Shuttle missions began photographing the surprisingly plentiful phenomenon of severe storm cloudtop stratospheric "sprites." Directionality is only terrestrially misconstrued. Overall, discharges seem to go both ways. And don't forget, that those of us that have traveled extensively by air have experienced cloud-to-cloud discharges with some frequency that never reach the ground. What's important is the presence of potentially conductive piezoelectric materials in sufficient quantities and moving at right angles with sufficient delta "v" to the Earth's geomagnetospheric field lines to induce the discharges. The amount, frequency and durations would be related to the amounts of piezoelectric materials and magnitude of delta "v."
