Probably talking about potential. So you can have an accumulation of charges on one side(surface) to determine the potential and then you could have either a positive or negative electric field depending on the balance of charges.

Assuming that the Earth has an excess of electrons "the field is then independent of the radius."

Learning as I go about this charge/polarity thing, and it gets quickly more complicated.
The rock below us is layered and of widely varying compositions. The orientation of the crystal latice of the various layers changes the electrical characteristics completely, making it very difficult to predict a consistent voltage gradient or polarity. What we end up with is a very complex multi-layer ceramic capacitor, where voltages could build up to multi KV levels at the boundaries of some layers. Charge may also migrate laterally in some layers over large distances and accumulate in specific formations, causing mechanical stresses and even changing the crystal structure of layers if a dielectric breakdown occurs. Then there are localised piezo electric/mechanical effects. Apparently a good percentage of earthquakes at some depths are due to large masses of rock re-arranging their crystal structures and contracting by cubic miles in volume. This isnt just any old piece of rock we live on!

Hmmm.. this sounds like what I've been looking for:
Since electric field is a function of distance from charge, we conclude that it will be the same at all points that are equidistant from the charged shell. Hence, the electric field has a spherical symmetry around the shell. This means that it is radially directed, either outward if is positive, or into the shell if is negative. Therefore, the angle between the field direction and the outward normal to the surface is either (for positive ) or (for negative)

Embarrassment of Riches. Birkeland Currents Verified AGAIN!

Unread postby MGmirkin » Thu Apr 23, 2009 4:39 pm

(New Finding Shows Super-Huge [Electric] Space Tornados Power the Auroras)
http://www.universetoday.com/2009/04/23 ... e-auroras/

I can't help but laugh... i mean it's serious science, finally, but it's just so comical to see them "finally" figuring out what we've been trying to tell them for MANY, MANY YEARS. I mean, Birkeland predicted this over a hundred years ago.

Image

The Triad satellite verified it in 1973. THEMIS already re-verified it in 2007-2008. Now they're finally calling it like it is!

...electrical funnels which span a volume as large as Earth produce electrical currents exceeding 100,000 amperes. THEMIS recorded the extent and power of these electrical funnels as the probes passed through them during their orbit of Earth. Ground measurements showed that the space tornadoes channel the electrical current into the ionosphere to spark bright and colorful auroras on Earth.


Space tornadoes are rotating plasmas of hot, ionized gas flowing at speeds of more than a million miles per hour, far faster than the 200 m.p.h. winds of terrestrial tornadoes...


Both terrestrial and space tornadoes consist of funnel-shaped structures. Space tornadoes, however, generate huge amounts of electrical currents inside the funnel. [Actually there's plenty of anecdotal evidence that tornadoes have electrical stuff going on inside too, but that's another story...]


These currents flow along twisted magnetic field lines from space into the ionosphere where they power several processes, most notably bright auroras such as the Northern Lights, Keiling said.


The THEMIS spacecraft observed these tornadoes, or “flow vortices,” at a distance of about 40,000 miles from Earth. Simultaneous measurements by THEMIS ground observatories confirmed the tornadoes’ connection to the ionosphere.

I'm so cheering these latest in situ findings Michael. 100,000 ampere Birkeland currents. I think Birkeland would kick back and enjoy this as much as I DO!!! :D

Excellent information!!

http://www.nasa.gov/images/content/2037 ... er_400.jpg

From many moons ago now.

Now, on another note, I might have been slightly off... But not by much. This new report, if I understand correctly, talks about the magnetotail with respect to the currents.

However, it still appears to be the same process as the "magnetic flux ropes" yadda yadda... IE, field aligned currents. And we know that the field-aligned currents trace all the way back to the sun.

We also know that the auroras shine 24-7 in the UV portion of the spectrum. Even if we can't see them in the visible band, satellites pick them up in the frequencies they see...

(Auroras in Broad Daylight)
http://science.nasa.gov/headlines/y2008/06mar_polar.htm

Why is that important? Well, the auroras are an electric phenomenon. If they're constantly lit up, it means they're constantly receiving a current. Take away the current from a neon tube and it quickly turns off and stops emitting. So, it seems the current input into our auroras is a constant thing. Sure there are power surges that give more impressive visible light shows. But it's always there. That seems to argue for a continuous circuit, rather than an intermittent electrostatic discharge. The question then becomes where the driving force behind the circuit comes from to sustain it...

I tend to think that the electric sun model is the right one. More or less, the sun is the central electrode od the system and the planets constitute minor loads in the overall solar system circuit diagram.

Kind of like the really old analogy I used a year ago of the solar "plasma lamp," with the planets acting like fingers pressed against the glass attracting more-or-less permanent currents to those points.

Get to the basement, a SPACE TORNADO approaches

Unread postby rcglinsk » Fri Apr 24, 2009 1:07 pm

http://www.cosmosmagazine.com/news/2713 ... ly-auroras

The good people at cosmos magazine managed to suspend their disbelief and observe...

A cluster of NASA probes have revealed the existence of vast "space tornadoes" which – at 70,000 km in length – are big enough to envelop the Earth, and produce electrical currents exceeding 100,000 amps.

The five THEMIS (Time History of Events and Macroscale Interactions during Substorms) probes recorded the extent and power of these electrical funnels as they passed through them.

Ground measurements further showed that the tornadoes channel electrical current into Earth's ionosphere to create bright and colourful auroras.


That's three sentences, two "electric currents" and one "electric funnel;" truly groundbreaking comprehension.

"Space Tornado" could use some work. It is nice to see though that THEMIS has confirmed space electric currents take the same form as field alligned currents in labs.

THEMIS Discovers What Triggers Eruptions of the Aurora

Unread postby mharratsc » Mon Apr 27, 2009 1:49 pm

Herein lie the words of our best and brightest, armed with the most advanced technology our world can develop... and yet completely devoid of an elementary physics education...

[url2=http://www.nasa.gov/mission_pages/themis/auroras/themis_power.html]THEMIS Satellites Discover What Triggers Eruptions of the Northern Lights[/url2]

This is the best part:
These observations confirm for the first time that magnetic reconnection triggers the onset of substorms. The discovery supports the reconnection model of substorms, which asserts a substorm starting to occur follows a particular pattern. This pattern consists of a period of reconnection, followed by rapid auroral brightening and rapid expansion of the aurora toward the poles. This culminates in a redistribution of the electrical currents flowing in space around Earth.


Spoken with such confidence, too :\

Pure Electric Universe does NOT include magnetic reconnection. Magnetic reconnection doesn't exist, it's a fabrication like dark matter/energy, black holes, etc.

http://members.cox.net/dascott3/IEEE-TransPlasmaSci-Scott-Aug2007.pdf

It is clear that a rigorous understanding of the real physical properties of magnetic fields in plasmas is crucial for astro
physicists and cosmologists. Incorrect pronouncements about the properties of magnetic fields and currents in plasma will be
counterproductive if these conceptual errors are propagated into publications and then used as the basis of new investigations.
There are some popular misconceptions.

1) Magnetic “lines of force” really exist as extant entities in
3-D space and are involved in cosmic mechanisms when
they move.
2) Magnetic fields can be open ended and can release energy
by “merging” or “reconnecting.”
3) Behavior of magnetic fields can be explained without any
reference to the currents that produce them.
4)Cosmic plasma is infinitely conductive, so magnetic fields
are “frozen into” it.



Many astrophysicists, when presented with these ideas, will
acknowledge that magnetic lines of force are only abstractions and not real-world extant objects. However, there is no
justification for statements such as “For many years [these
lines] were viewed as merely a way to visualize magnetic
fields, and electrical engineers usually preferred other ways,
mathematically more convenient. Not so in space, however,
where magnetic field lines are fundamental to the way free
electrons and ions move. These electrically charged particles
tend to become attached to the field lines on which they reside,
spiralling [sic] around them while sliding along them, like
beads on a wire [14].” This erroneous concept becomes doubly
dangerous when the magnetic field lines themselves are also
thought to be able to move, as in magnetic reconnection.

Did you actually read the Wikipedia article? Though they label it "magnetic reconnection" they explain it is pure plasma physics. No mentioning of "open ended" magnetic field lines anymore. One can create the effect with two refrigerator magnets even.

Yet they still seem to refer to field lines as real entities that can be "spliced together"

field lines enter the separator from two of the domains, and are spliced one to the other


they also refer to

bundles of field lines that connect from a particular place to another particular place


Magnetic fields are solenoidal. That is they never begin or end. They form continuous uninterrupted loops. The net magnetic flux is ZERO. Ergo, the same number of field lines entering a closed surface must also exit it. The same number of field lines exiting a surface must also re-enter it. One-way field lines with no equal but opposite field line going the other way violates Maxwell's equations.

http://farside.ph.utexas.edu/teaching/e ... ode35.html

B is a solenoidal vector field. In other words, field-lines of B never begin or end.


In fact, permanent magnetism is generated by electric currents circulating on the atomic scale, so this type of magnetism is not fundamentally different to the magnetism generated by macroscopic currents.


In conclusion, all steady magnetic fields in the Universe are generated by circulating electric currents of some description. Such fields are solenoidal: that is, they never begin or end, and satisfy the [second of Maxwell's field equations]


The Wikipedia page speaking of field lines that "begin here" and "end there" appears to be in error (unless of course they're being as sloppy as usual), with regard to Maxwell's equations. There are no magnetic monopoles, and there are no magnetic fields that either begin or end. They are continuous loops.

Field lines are only visual constructs and DO NOT exist in 3D space. Ergo they cannot "reconnect." The field lines are redrawn each instant as the underlying currents change. As Don Scott says, it is not the "same line" that has merged with another line. The entire set of lines has been redrawn for that instant in time, taking into account all the various interacting things that happened in the previous instant. I see they cite no sources for the "refrigerator magnets" line talking about "constant reconnection" of moving nearby magnets. Do they claim that subatomic magnetic fields are generated in a way different than macroscopic fields? If not, then it seem that any changes in macroscopic fields between the magnets likely come from the changes in the charged particle behavior around the nuclei of the atoms of the magnets themselves. Sine it's that charged particle net differential motion that (most likely) leads to the magnetic moment of ferro-magnetic materials.
