Re: Cusps of Earth's magnetosphere

Mingling lines of magnetic force from the sun and Earth criss-cross and join to create the openings. "X-points" are where the criss-cross takes place. The sudden joining of magnetic fields can propel jets of charged particles from the X-point, creating an "electron diffusion region."
Thanks for the info., but this makes my brain hurt, trying to understand how it works.... :?

Will just have to accept the data of the effect. :|

_ A so-called electron diffusion region. It is a boundary just a few kilometres thick that occurs at an altitude of approximately 60000 kilometres above the Earth’s surface, where electrons can be accelerated to approximately one hundredth the speed of light. On 25 January 2005, and for nineteen times in one hour, the Cluster quartet found themselves engulfed in an electron diffusion region.

“Understanding the structure of the diffusion region and its role in controlling the rate at which magnetic energy is converted into particle energy remains a key scientific challenge,” says Dr Michael Shay, University of Delaware, USA.
Until recently, theoretical scientists believed that the electron diffusion region was relatively tiny (width about 2 km, length about 10 km)...

Comparison between observations and simulation
On 14 January 2003, the four Cluster satellites were crossing the magnetosheath, a turbulent plasma region located just outside Earth’s magnetosphere, when they encountered an electron diffusion region. The length of the observed region measured 3000 km, 300 times longer than the earlier theoretical expectations and four times longer than seen in recent simulations. Nevertheless, the observations strongly support new simulations.

Sparky,

Apparently they have been working on this data forawhile and have just recently decided that these cusps, forming periodically at junctures of the solar magnetic flux and the earth's magnetosphere, can form "portals" which conduce a rush of ions ("accelerate the plasma away from the X-line") right through our magnetosphere.

Here the electrons are provided by the current sheets which collimate the earth-magnetosphere like the layers of a big green-onion / shallot,
~ but comes to mind the physics of an old TV picture tube where diffuse electrons (from the the wall outlet) are collimated by the magnetic yolks (cusps) and and shot down tube, like a portal to our eyeballs.

Magnetic Field Decline Started in 1860
* That's what this article says: http://www.newscientist.com/article/dn9 ... cline.html. It says before 1860 the decline was negligible. So it's been declining only for 150 years.
* What caused the decline to start at that time?
* Wikipedia says: Its magnitude at the Earth's surface ranges from 25,000 to 65,000 nanoteslas (0.25 to 0.65 gauss); ... the present strong deterioration corresponds to a 10–15% decline over the last 150 years and has accelerated in the past several years....

The ships logs only measured the direction of the magnetic field, which could include the angle into which the field entered the ocean. And then the article goes on to mention that the major difference is located around South America. And the article mentions measurements of bricks and pottery, etc, without mentioning more ancient measurements of such, or producing a graph of these results.

So all told - a pretty poor article.

How the EUT deals with Earths Magnetic Field

Unread post by project722 » Thu Oct 11, 2012 7:50 am

In the EUT, how is the earths magnetic field generated? Does the dynamo effect still hold water in this model?

Earth's magnetic field is an even bigger mystery. Some mechanism obviously generates the field, and many scientists think the field is formed from fluid iron in Earth's main outer core acting like a giant electric dynamo, or motor. The geomagnetic field, as it is called, shuts down periodically and sometimes reverses its polarity -- with the North and South poles exchanging their magnetic charges.

The energy sources previously thought to power the dynamo are unable to decrease and then increase again, Herndon explained, so scientists have had to resort to assuming the dynamo mechanism is inherently unstable.
Interesting idea, supported by evidence.

Longevity of Earth's magnetic field.

Unread post by cantdrive85 » Sun Aug 11, 2013 11:10 am

The question pertains if the Earth was captured from the protective environment of a dwarf type star a few thousand years ago into it's current situation around the Sun. The idea that the Earth's plasmasphere is protecting us from the Sun's plasma environment presents the question of what happens if/when the Earth equalizes to the Sun's plasma environment. I guess the first question is, will it equalize? Will the electromotive force produced by the the Earth's rotational "orbit" prevent an equalization? Or, will the plasmasphere weaken over time as the Earth slowly equalizes itself to the Sun's electrical environment, exposing the Earth to more and more harmful radiation? Or, does the Sun's variability ensure the needed difference will remain, given the catastrophic events Mars was surmised to experience does not happen. Any thoughts?

You might want to read the thing I posted a week or so ago about Troy McLachlan's take on intrinsic magnetospheres, particularly those of Earth and Ganymede. The intrinsic magnetospheres of rocky bodies appear to have been fused in by strong Birkeland currents which are no longer there. The Earth's magnetosphere in fact is weakening.

Troy and I assume that Ganymede's magnetosphere is fused into a deep outer mantel which we believe consists of pumice rather than salt water, and is conductive because of p-hole structures, the effect of which is enormously magnified by the huge surface/volume ratio of the pumice.

I was under the impression THEMIS discovered vast Birkeland currents not too long ago

Are these portals Z pinches?

Unread post by Sparky » Sat Aug 24, 2013 9:13 am

I was looking at this video and it seems that the magnetic field pinches, forming what is called portals.

What do you see? :? Thanks

What would you call them? The reference is to the moments when charged mass is exchanged from the Solar Wind and CME’s into the Earth’s Magnetic Field. The description is of the EM connection between the Earth and the Sun. Are you suggesting that doesn’t fit the EU model? Are they a Z Pinch? Plasma is exchanged from one magnetic field to the other, what is the EU description of the phenomenon?

Portals, magnetic reconnection... :roll:

Not sure if they even have a name. If you have two filaments in a plasma ball that al of a sudden join together, what would you call it? What about when they separate? These phenomena like so-called magnetic reconnection and I guess portals too, have to do with electricity (charge) seeking to reach the Earth. the magnetic field lines merely provide a path of least resistance. Since plasma is a gas (free to move charged particles), things can get turbulent out there. the question is why are these charges attracted to the earth, is it due to a charge imbalance? Or is it looking for a short-circuit? I disagree that plasma is "exchanged" from one field to another, but I think now I understand why they call them "portals". I don't know if there is an official EU description of portals. maybe someone else knows.

Well, I don't know... :? At 31 sec. the lines of force come together, in what I assume to be in reality, a pinch. At the 2:19 mark, the complex interaction appears to me to be plasma ropes, wound tightly and distorting the Earth's Magnetosphere. :? Is there more energy needed for a z-pinch? :?
At 45 sec. it shows a connection between Earth and the Sun. Is this a current with associated magnetic field? :?
Thanks ;)
