Earth's magnetic field - 05/2007

[cblazer]

i have a question does the earth and sun's magnetosphere act like normal magnets.. like when you have a north and south that attract each other and south and south repel, north and north repel. Does the sun and earth react the same way and how does the polarization effect the solar winds, coronal mass ejections etc?

[thatonekid722]

may be a stupid question, but why is the magnetic field streched on one side and shorter on the side facing the sun?

So, the solar wind is a ionized gaz and so it interact with the earth's magnetic field. The field is deformed in the direction along with the wind blow, shorter on the side facing the sun because of the pressure of the wind as the air wind could do it, and streched on the other side.

Thank You for the reply.

While watching this, I suddenly realized that I'd seen an image much like the still frame representing the magnetosphere above. I did a quick Google search on it, and I found it. Within the region of the Nazca Desert are the infamous Nazca Lines. One of the geoglyphs there looks kind of like a spider but with 6 legs instead of 8. When I compared the above image with the glyph, I was amazed. Very, very similar. Makes me curious as to what the intended message is.

I wonder if we should be carving out rare earth magnets out of the planet and spreading them out across the world. Just a 1/8th inch piece is really powerful, I wonder if dissolving a mountain size piece could effect the whole planet. I guess it wouldnt matter. You cant stop the profit machine.

annoying music tbh

[enzo396]

@magnitooo What do you suggest ?

[magnitooo]

@enzo396 im suggesting a guy talkin and explaining wuts hapening

[OriMedian]

How far does the magnetic field of our earth stretch? or does that depend on solar activity?

[7Supernova7]

i dont get part two with the hour clock? what is he trying to show,? thanks for reply

@CommanderCody88 I don't know if I've understood you correctly, but the sun's and earth's magnetic fields aren't responsible of the orbital trajectory of earth around the sun. According to the most recent theory of Albert Einstein general relativity, it's because of the distortion of space-time by the earth's and sun's masses. But it's still a good question to know why it's more the gravity than the magnetic field who influences the orbital trajectory.

[enzo396]

@CommanderCody88 Finally, as we can see it the symmetry breaks appear during the earth's rotation in a day. Because the sun wind pressure is constant and uniform, the answer is somewhere in the description of the earth's inner core which is responsible of the earth's magnetic field, and the earth's position which is inclined in his orbital plane around the sun as we can see it in my new video.

[enzo396]

@CommanderCody88 The answer is not simple, as to describe the behavior of real physical objects. Imagine a falling leaf tree, which is influenced by his shape, his mass repartition, the complex distribution of wind pressure and maybe you if you touch it etc.

The videos of the earth's magnetic field come from the visualization of Dr. Nikolai Tsyganenko famous models, who aim to have a formal description of this object.

[majik2hanz]

Wouldn't the earth's magnetic field have a 'bloch wall'? In other words, wouldn't this model of magntic fields look more like a figure eight with concentric circles flowing out from each pole opposite in spin and then back inward at the equator?

Thank you. Very good modeling illustration.

The wonders never sease to unfold on this planet.

[Titttoh]

whats the name of the song? THX!

[xizb10]

@Titttoh I am not exactly sure wich part it is, but it is Vivalidi's  4 seasons. Sounds like spring does'nt it? ;)

[Symphonya90]

@Titttoh Vivaldi's 4 seasons - Winter :)

[JeremiahDaradal]

the earth is so beautiful! no wonder aliens don't want to destroy it! j/k

[RG15GOLF]

LoL... get back to me with more jokes!

[Hymanroth67]

that's scary.

[11moonelf]

it's actually quite beautiful~

[obserwator51]

No dobrze. Ale dlaczego magnetyzm Ziemi jest większy po jednej stronie, a po drugiej mniejszy? To nierównomierne rozłożenie pola zastanawia.

[ncreda]

Looks to me like we are on a beautiful vessel sailing through the dark sea.

[lloplop]

exact the we seem to be stationary

[11moonelf]

amen~

[tharnax]

Most people do not realize that Earth is a gigantic magnet.

[ftpaddict]

Excellent choice of music. Moby goes very well in this case. :)

[Russett420]

nice

[gotramaval]

Why isnt symmetric? its cause sun magnetic field?

Thanks

[enzo396]

I don't believe, even if sun and earth magnetic field are connected. Because as we see it the shape modification occur during a day.

[gotramaval]

But, the magntetosphere is elongated in the way of the line conecting sun and earth, isnt it? I think shape modification can occur with the variation of the sun-earth distance or with the earth rotation... Dont know...

[enzo396]

No, the only significant influence from the sun is the strength of the solar wind, which is responsable of the comet like shape. One probable parameter of modification of the shape is the earth inclination.
