Kooky questions |
1 Where does the earth get it's magnetic field?
2 Could it possibly be from it's core?
3 If the earth's core is molten iron, how might it keep it's magnetism?
4 If the centre of the earth is some miraculous ball of molten iron that
has maintained its powerful magnetic force all this time, why don't the
liquid s pole and the liquid n pole migrate toward each other and
neutralise each other?
5 How does a simple magnet made of iron manage to get its field through
so much cladding?

1 Where does the earth get it's magnetic field?
K-mart, blue-light special.
Almost as good as a dipole filed, but a lot cheaper.
2 Could it possibly be from it's core?
No. Not the way you meant the question, anyways.
For all the reasons you allude to in your following "questions".
Google, seach term "geodynamo".
Flip through a couple of the resulting links. They're quite interesting.

Take two permanent magnets, and try to push the poles together
and you will feel them push apart.
You can feel the force.
Yet it is invisible. But it is there.
You can put paper between them and still it is there.
Miraculously it appears to go right through the paper,
as if the paper was not in contact with magnetic force
at all.
But the em waves, which are on the same basic frequency
will affect each other, while the matter inserted between
them is unaffected.
When two waves cancel out, they create a low pressure area,
and the poles attract. Likewise, when two waves add together,
they form a high pressure system. The poles are forced apart.
The fundamental reason that planets are round, is due to the
expansion of the universe. Where not only the space between
objects expands, but so does matter itself.
But it doesn't expand all ay once.
For there is resistance.
But it is pushed along, on waves of expansion.
The waves themselves, are basically em waves.

The fundamental reason that planets tend to be spheroidal is
due to their self gravitation. Newtonian mechanics applies.

Ref: http://www.sigmaxi.org/amsci/articles/96articles/Fuller.html
The first evidence that the earth's magnetic field has reversed many
times in the planet's history was discovered in 1906 by Benard
Brunhes. Ninety years later, earth scientists are only beginning to
understand the nature of these phenomena. By studying the
plaeomagnetic evidence left in igneous and sedimentary rocks, the
authors study the behavior of the magnetic field during reversals and
find that there may be predictable patterns to magnetic polar
wander-along a corridor traversing the Americas. The implications
for our understanding of the earth's outer core, the electrically
conductive fluid that is thought to generate the field, may be profound.

Hey Al. Are you a graduate of the Attila the Hun Charm School? C'mon.
For crying out loud, the guy was just asking a couple of questions. If
he doesn't have quite the same background as you, why can't you be
civil, and help him out a little?

Uncle Al is a true ***** and a shitty physicst. A real physicst knows how
to teach.
The earth has a nuclear reaction at it's core. This reaction is what
creates the heat which makes the Earth alive. The molten core also happens
to rotate at a different speed than outer layers and thus create a potential
difference, and a magnetic field. Heavier metals continue to drop towards
the core and keep the reaction going. Every once in a while, the reaction
stops due to lack of density of fissionable material (because of build up of
by-products). Supposedly, we're due.

Know how you teach a mule? You hit it in the head with a baseball bat to
get it's attention FIRST!
Glad I'm just a dumb Field Rock-Whacker rather than a physicst! I too have
problems spoon feeding information to those so lacking in self-motivation to
even attempt to locate the information themselves, particularly since this
is an Earth Science 101 "Rocks for Jocks" First Week question! If that
makes me an *****....so be it!

Maybe. But I have the feeling the OP is the one having a laugh here,
so at least he has the pleasure of having made Uncle Al look silly.
Not that that makes the OP a cool guy either -- just a different
species of annoyance.

And just what would happen then? Is this another cataclysm to worry
about right up there with global warming? The long term effects
actually might be like global warming ... only worse: no nuclear
reaction, no heat, no vulcanism ... eventually ... no land. Of course
this would take some time, and extrapolating from current technology
we could probably overcome it in the time available ... dredging
material from the sea floor if necessary, fusing it using nuclear
power, and pouring new molten rock -- artificial vulcanism.

Given the foregoing top post (infallable symptom of assholiness), my
post was precise and exact. People who know nothing begin their
education by getting educated. Things do not get interesting until
one knows enough to ask a good question. Autodidact.
"Scientific American" has had articles on the Earth's self-priming
liquid dynamo and why its internal spatially complex magnetic field
looks much like a dipole field at the surface. The original poster
needs to screw his ***** into a chair and use Google to survey the
field. Read what the researchers wrote, not the talking heads. When
he knows something useful he can formulate more functional questions
to be answered.
If he does not, all he will get is sorry crap like the top post.

Wouldn't it be nice if you had a clue instead of 'spewing' your knee jerk
reactions? I doubt McNeil is embarrassed because he asked questions the
true answers to which are not available from the so-called mainstream

Is there some reason that you're full of so much hate?

I don't think its a particularly stupid question. Not a great deal is known
about the earths interior so to accept as proven that the earth has a
self-exciting liquid dynamo that is creating a magnetic field when deep
refraction seismology and magnetic inversions are the only clues seems a
little stupid. Especially if your not devoting your life to Geophysics.
When you REALLY think about it - suggesting that the earths outer core is a
liquid and is rotating inside us at a angular velocity that is tangible
enough to cause a physical effect that can be observed on the surface seems
a little extraordinary. And it is! Whether or not the original question may
have seemed slightly ignorant, I would be quite interested to hear from
someone more educated than myself explan or debate the finer nuances of the
earths interior. I thought these newsgroups had the purpose of sharing
information and educating one another - not hoarding knowledge.
