Magnetism

@ Michael V,


Regarding your field effect diagrams, how would you describe a sphere that has two positively-charge poles, and a negatively-charged equator? Also, how would your thesis describe the activity of a homopolar motor, or in reverse, an object being a homopolar generator?

[Michael V]

mharratsc,

Regarding your field effect diagrams,

That should be "field emission" diagram. The interaction map or "force field" is the traditional pole to pole curved force lines diagram. My point is that the magnet does not emit the force, the mutual force occurs due to an interaction between the magnet and other magnetic/magnetisable objects. So the "lines of force" do not contain any force and the emission "fields" of two magnets do not and can not interact. The forces are forces of mediated interaction, not forces of influence belonging to the magnet, and in this respect the supposed "curved field" is highly misleading.

... how would you describe a sphere that has two positively-charge poles, and a negatively-charged equator?

I don't understand the question. What sphere,? Where? What's made of? Can you be more specific?

Also, how would your thesis describe the activity of a homopolar motor, or in reverse, an object being a homopolar generator?

The motor is a magnetic interaction resulting in a force. The generator is the application of a force to a magnetic interaction to produce electricity. Nothing too mysterious.

"an object being a homopolar generator" seems to be loading the question for a particular non-stated reason. Again, do you wish to be more specific?

Michael, have you come up with an explanation of magnets "attracting"?
I got the "repulsion" part..

[Michael V]

Sparky,

Yes.

However, I am being secretive about until I have completed my papers, which will hopefully be sometime this century.

If you would be so kind, would you please remind me what the cause of the repulsion is, thanks.

Good question about "mass" in the other thread. I was is the course of typing a reply, when all of a sudden I fell down a rabbit hole. I'll get back to you on that when I've finished checking for rabbits.

-what the cause of the repulsion is, -

hmmmm, well I thought is was the result of the aether emissions of aligned electrons, opposing the same from another magnet.....did i misunderstand or not see an additional process?

idonno..

MichaelV,

Just a note for clarification:
your magnetic "fields" are not the same as magnetic 'domains' ,

[Michael V]

seasmith,

Would you please describe/explain, in as plain and simple terms as possible, what you mean by "magnetic domains".

Michael

[seasmith]

M,

I'm still working on a more precise topology, but to use a crude 3d terrestrial analogy, ' emission fields' are where the corn is propagated, the 'domains' are (volumetric farms) in the natural terrain, that are disturbed by the plowed fields.
In other words, emission flux fields characterize their domains, but are sustained and contained by their ambient aetheric terrains.
That would be why different substances support different degrees of 'magnetic permeability';
and why i agree with your term "interaction".

seasmith,

Cryptic and ever dude. I did say "plain and simple terms", you little tinker. Nevermind, my understanding of "domains" is that they are caused by a random inhomogeneity in the structure of the magnetic material. I don't see this as of any particular interest with regard to magnetism and lies more within the realm of materials science. I stand to be corrected if you are able to convince me that it is more interesting or important than I have initially concluded.

Random ??

Many modern data storage devices, like hard disk drives, rely on the ability to manipulate the properties of tiny individual magnetic sections, but their overall design is limited by the way these magnetic 'domains' interact when they are close together.

You find that "cryptic" ??

The heliospheric sheath is a domain, but of course uninteresting and unimportant

[Sparky]

The heliospheric sheath is a domain,-

Now confused again.....I thought domains were homogenous within each?

Does the sheath exhibit such property?...thanks

[seasmith]

Sparky,

I was quick to hit submit and late to editate there.
Should have said 'in effect' a domain. In fact we have almost no topology on the heliosphere and are not even sure of it's general form.
Function, however, fits with that of 'magnetic' domains. It is the dynamic interactive interface between the flux of the sun and the ambient aetheric terrain (and magnetic topography) through which it is traveling.
Since there are no real magnetic lines, it would appear to be the contingent magnetic deformations/formations (ie domains) of local [and ambient] aetheric matrix
which are interacting. A little bit like two soap bubbles meeting within a a third encompassing bubble, but much, much more dynamic.

For our heliosphere, you have the local magnetic generator (the sun), with variable output, bowing out a non-homogenous 'sphere', and traveling through a non-homogenous spatial terrain; which is itself an intricate swirl of merging and diverging galactic and cosmic electromagnetic domains.

[Of course the E and M cannot be separated, but it is the flux fields, not Efilaments, which really fill up the heliosphere.]

The "sheath" may well be typical electric double-layer. We do not have a clear picture of magnetic interactions in either one, so your question is ?

Comparing interactive domains- Heliosphere and CME models



(a) An interplanetary coronal mass ejection (ICME) and (b) the outer heliosphere both present shock (CME-shock and termination shock) and sheath (CME- sheath and heliosheath) features. In this work, we draw on analogies between the two structures. The effect of the interstellar magnetic field (BISM in the outer heliosphere) corresponds to the effect of the magnetic field in the ICME (Bejecta). See the Introduction section (Section 1) for a detailed discussion. This figure has been adapted from Opher (2010).

The HP is distorted by the interstellar magnetic field pressure due to the compression of the magnetic field against the HP by the slowdown of the approaching interstellar flow. This slowing causes the magnetic pressure to dominate the thermal pressure close to the HP, forcing it to align with the interstellar magnetic field (Opher et al. 2007, 2009). The subsonic heliosheath flows downstream of the TS are immediately sensitive to the shape of the HP and therefore can probe the interstellar magnetic field direction (which is poorly constrained). The Voyager 2 spacecraft crossing of the TS (Stone et al. 2008) provided the first in situ data of the heliosheath flows. Opher et al. (2009) used a global simulation and Voyager 2 observations of heliosheath flows to constrain the interstellar field magnitude and direction.

The analogous quantity to the interstellar magnetic field in the ICME case is the ejecta magnetic field. The photospheric magnetic field from synoptic maps, specifically the neutral line of the source active region, is used to constrain the ejecta field direction near the Sun. The presence of a sigmoid can constrain the CME's orientation, as the material often aligns with the neutral line of the active region (Sterling et al. 2000; Gibson et al. 2002). However, the neutral line structure is often complex, especially for active regions which produce fast CMEs (Wang & Zhang 2008). Additionally, studies have found the ejecta's field orientation to lie both along and across the neutral line of the source active region (Zhao & Hoeksema 1998; Wood & Howard 2009). There is also an example of in situ flux rope signatures with no identifiable source active region (Robbrecht et al. 2009).

seasmith:

Well, my picture is very vague, so anything that would clarify is helpful.

Thank you, even though i am having difficulty digesting your posts...Will keep rereading...

Interacting magnetic fields may be too abstract for me...

All I can see is that the sun is a domain of domains...

Thanks

[seasmith]

Me too ...

Sparko mi bro, sometimes a [mere] representation appears obtuse, but perhaps it is just unfamiliar in the sense that words are fungible. and institutional techno-jargon is entertaining tho not absolutely necessary .
Just look again at the twin images above. They stress the dual effect of each: solar wind ≠ solar ejecta
and B-ism ≠ B-sw.

But back to the crude and clumpy molecular analogy, bubbles.
"Fields", like air in a balloon, don't contact the air in another balloon. Whatever that interface/interaction is, are 'domains', and are impelled by electromagnetic fields. Hope that is clearer.
You ask some challenging questions.
