Earth’s magnetic field is not produced by an internal dynamo within the planet
Dennis Brooks ^ | 2009 | Dennis Brooks

Posted on 10/27/2009 8:12:33 AM PDT by mudblood

The New Theory: Earth’s magnetic field is not produced by an internal dynamo within the planet. The magnetic field and the planet are separate parts of a complex dynamo system surrounding the planet. The system includes the planet, the magnetic field, radiation belts, and ring current. The same is true of the other planets. Saturn, Jupiter, Neptune, and Uranus are visible components of otherwise invisible planetary dynamo systems, which are all housed within a magnetosphere. According to this new theory, there is no internal dynamo within the planet. Planet Earth does not have a unique way of producing it’s magnetic field. Nor do the other planets. Each magnetic field of each planet is produced in exactly the same way, by its planetary dynamo system.

We’ve seen what happens when people accept established science as the end of all further inquiry (global warming).

True. While science has accumulated a vast amount of knowledge, even great theories like General Relativity are incomplete.

Mars and I believe Venus have almost non existent magnetic fields. In the case of venus its interesting due to the fact that we don’t understand what prevents the atmosphere of venus from being stripped away by the solar winds.

you wonder how a ball of iron the size of mars, spinning opposite to the Earth’s rotation at millions of miles per hour, could produce a magnetic field?

That view was popular, but never did make any sense.


Probably only because you are not up to speed on the equations of magnetohydrodynamics. Walter Elsasser would be disappointed in you.

Anybody can have theories.

To paraphrase “Rocky Horror Picture Show”:

“I’ve got theories, you’ve got theories, we’ve all got theories!”

I’ll believe it when he produces a scientifically accurate dynamic physical model that predicts the periodical pole reversals.

There’s a definite cycle but you would have to ask a geologist for theories on what causes it. I believe the name of the ship that discovered the magnetic banding of the sea floor was called the Glomar Explorer.

As far as magnetic field weakening is concerned, it makes sense that as a molten core cooled, the magnetic field it produces would weaken.

Then you shouldn’t believe that the liquid core produces the Earth’s magnetic field, because scientists cannot predict pole reversals either, nor explain why. From National Geographic:

“We can see reversals in the rocks, but they don’t tell us how it happens,” said Gary Glatzmaier, an earth scientist and magnetic field expert at the University of California, Santa Cruz.

Also:

“Our planet’s magnetic field reverses about once every 200,000 years on average. However, the time between reversals is highly variable. The last time Earth’s magnetic field flipped was 780,000 years ago, according to the geologic record of Earth’s polarity. “

Glad to have you on-board with us Dynamo-ers!

So, can this guy demonstrate then the magnetic movements and reversals the Earth experiences? Magentic North moves about 0.1 degrees per year where I am at. The Sun isn’t moving that much. He would need to explain the interaction between the Sun and the Earth in order to prove his theory.

So, how did you and Mars come to that conclusion? he he

It might be interesting to look at basalt deposits, say on the Moon and Mars and see if they can be corellated to terrestrial shifts.

Although there seem no appreciable tectonics on these two bodies, basalts ex/intruded at different times could then be compared to events of similar age on Earth.

If the events are synchronous, maybe this guy’s onto something.

But I personally doubt it.

The sun itself presents some problems for the guy’s theory. The sun isn’t a solid mass and doesn’t rotate at the same rate all over its surface. This causes a chaotic magnetic field that you would expect to make earth’s magnetic field just as chaotic.

Please tell us how Nikolai Tesla powered his “electric” car back in 1931. No battery pack, just 12 vacuum tubes and two ferrite rods I ass-u-me were cores for low frequency inductors/coils of some kind.

Basically the huge eddy currents created as the core interacts with the mantle.

Very true. IT also would give the guy’s theory problems in that the particles from the Sun also are not as constant as the magnetic field of the Earth.

I suppose if you could take deep core samples from the slope of Olympus Mons we might be able to find out if there’s any banding there.

I think we should build giant super conducting magnets to supplement or decrement Earth’s magnetic field so we can control the temperature on the planet. Because the Magnetic field affects weather and climate much more than CO2 levels. Heck, building this system would probably cost 1/100th as much as Cap Trade.

Of course there is the possibility that HAARP already does something similar.
