That first answer wasn't very good, was it?  "Magnetic Circuit" kind of explains the phenomena,
what ever that is. Had to think on that one abit for a {hopefully} more fundamental view.

Try this -> The magnetic field "in" the iron is like the magnetic field in a bar magnet.

The field, - ""as we see it"" - , is not really "in" the "iron" or "bar;" it's the field in close proximity to, or
around, the iron or around a permanent bar magnet.  If 'the field were only inside the iron or bar, it would
not do us much good. Atomic Magnetic Domains reside within the iron (a.k.a. sort iron or electrical steel)
and is easily magnetized and de-magnetized, whereas a permanent magnet bar will maintain it's magnatism.

The magnetic field will also "couple" between other unattached "iron" close by. The space
seperating these two, or more, "irons" (the gap) results in losses - that's where the "Magnetic Circuit" analysis
helps us to determine those losses and adjust our design accordingly (e.g. saturation, etc.).

Note we can control the (magnetic) field around the iron but the (magnetic) field around the
permanent bar magnet is always there. Also, since the "u" in air is a lot less than that found in metals, often
times it's almost invisible in CAE simulation cartoons, even for small "gaps," but the Field will traverse
from one "iron" to another close adjacent "iron," and in some cases the gap loss with not be much.

The field rapidly falls in air (air u~0) so we configure our pick-up windings (induced) in the "close
adjacent" iron in some fashion that affords good/reasonable magnetic field coupling with the windings.

If we left the pick-up windings in the air close to the "inducing iron" the coupling would be very inefficient,
plus the field would be partially blocked by the close copper layer and the outer copper layes would see
much less of the magnetic field. This appears to have been a drawback in the early Gramme generators.

Instead, we surround (as best we can) the pick-up coils (LAP) by the coupled magnetic field from the Rotor
Coil Poles to capture as much of the field as we can (e.g. by using stator slots). Lots of various schemes
for this but that's the basic idea.

Sounds simple enough; but these basic things seem to stump, it appears, even some of the experts here!

Edit: added clairifications and corrected spelling errors.

Hi SL,
In your most recent post you said "Except, I can't seem to find any of your claimed "knowledge and experience" in your posts - what have I missed?" It didn't take long to find an example where you could benefit from me. I didn't post it at the time, last week, because you're unappreciative and the post wasn't directed at me. There are numerous examples where, mostly, you call me picky or petty and insult me just for giving valuable information.

Your whole explanation is, let's say, confusing from the technical side, but in particular, these parts are incorrect.
You say "air u~0"
I presume by u, you refer to permeability, or relative permeability. If so, air has a relative permeability of very, very nearly = 1.0, which
means it is essentially equal to the permeability of free space. See the chart and reference below.
You say "field would be partially blocked by the close copper layer"
Copper will not "block" magnetic field. Copper also has a relative permeability of essentially 1.0, very, very close to that of air.
Your comment about Gramme generators is total misinformation.

No wonder you like Holcomb so much. His and your gibberish sound very much alike.

WOW - another Earth Shattering find! (u~0)...  Keep digging, it just gets better by the post!

It will stop thousands from going down the wrong path... or, possibly keep them from discovering an
easily built and simple to understand excess energy scheme.

Disadvantages in the Gramme Generator are common knowledge, BTW. [drop a magnet down a copper pipe]

Give it up man! Leave it up to those that "can" and "are" doing it right now. Wantabees only get in the way!

 

Hi SL,
You don't have a copper tube, do you? Try your magnet drop down a solenoid coil of #28 copper wire, similar to the context of the application at hand.

Care to support your claim about the Gramme ring with more than generality. Gramme ring had drawbacks but magnetic blocking effect of copper was not one. Look it up.

You never did have big boy pants, did you?
bi

Let me ask, before I forget: 

How did your posted Linear graph of the GO-35ZH135 change anything from the posted Log graph?

I didn't quite catch that. Give it up man! Your getting in too deep with your limited knowledge...

Sticks and stones are giving away your Troll shield, BTW. Those kind of things don't work anymore.

SL

Hi SL,
You really don't pay attention or are easily confused. I didn't post a linear GO-35ZH135 graph. You did.

You say I have "limited knowledge". Maybe I should limit what I pass to you. If you study up on it and can ask an intelligent question, I'll do my best to explain.

You're the guy who says he has big boy pants, but can't answer simple questions and seemingly can't tolerate criticism. Did you buy that steel yet?
bi

You didn't even attemp to answer my question - instead changed the subject - what does that indicate?

So again - How does your posted graph alter the B-H analysis of the material?

"Maybe I should limit what I pass to you." -  Well that would be more than nice; great in fact - your
infomation is, well, silly and of no value what so ever, to me or anyone else. That would be great - thanks!

SL

Hi SL,
You have yet to ask an intelligent question.

Why ask me anything if my information is silly and of no value?

How much GO-35ZH135 did you buy?
bi

Wow.

CLOWN - TROLL Exposure and What To Watch Out For

Normally I would cut the nonesense posts off before they propagate to a stupid level,
however I let this series roll to bring out a very important point that we all face when using these
public forums. The following is from a old lecture but is still valid today.

How to Quickly Spot a "CLOWN" (some insight from the Experts(?)) Just so you can recognize it for what it is.
The term "CLOWN" as used here is generic and includes "TROLLs" and "LARPs,."

Don't get suckered into wasting your time. Hardened anons should already know this stuff; This is
more a crash course for new visitors.

Good stuff to be aware of; even if it would never happen here!

They will:

- Attempt to get a divisive or emotional response from you to derail research.

- Concern troll and copy/pasta spam shill to contradict confirmed findings.

- Employ faux debate tactics: Generalizations, gas-lighting, projection, misdirection, false equivalences, confusing
correlation with causation, appeal to authority, transference, false precepts, personal attacks, straw-men, red herrings, etc.

- Promote social ethics that are disingenuous like doxxing, "reverse psychology", or promoting propaganda.

- Promote tactics that are unethical, illegal or involve methods outside the scope of the Law.

- Employ Fear, Uncertainty and Doubt to dissuade research.

Topic sliding - If information of a valuable or informative nature has been posted on a discussion forum, it can be quickly
removed from public view by topic sliding. 

In this technique a large number of unrelated posts, or posts aimed at diluting the information presented, are submitted in
an effort to trigger a topic slide to literally push content out of view. Operators can control several fake UIDs via the bots they
make use of; these can also be called upon in the other techniques to mask the intent of the operator from the users at large.

Although it is difficult or impossible to censor the posting, unless the thread is moderated, the post is now lost in a sea of
unrelated and bogus postings.

Seeding bad information - Operatives will insert flawed or bogus information from time to time as an ongoing tactic, depending
on their skill set and the needs of their mission. Their most common ruse is providing information or evidence which is backed by
bad source material in the hope that the "source of the source" is never checked. This serves several objectives,
mainly resource consumption, evidence pollution, discouragement and misdirection.

Astroturfing consensus -This is a technique that attempts to build a manufactured consensus around a flawed set of statements
or compromised information. This is related to consensus cracking, where false evidence is injected in an attempt to dispute or
discredit what the current consensus is, and push it towards the desired false consensus.  Misleading and false evidence and
information are often salted into the evidence pool, with an aim to impede organic consensus building, while also poisoning the
available information and evidence.

Cultivating tacit approval (The legal term for this is 'silent agreement') - Attempting to attain this state is done using a
technique where operators will try to convince the user population to ignore, or not respond to bad information or false assertions.
This is done in a bid to reduce push-back against the above mentioned tactics.

It's worth noting that the reply filtering mechanism of the boards (which currently can't be disabled without code changes from
the site admin) is used as a weapon of sorts in this tactic: Filtering with software prevents anons from defending against seeding
bad information and astroturfing consensus. This is why the CLOWNS (operators) push so hard to condition anons into filtering
material they disagree with.

Also worth noting is it can be proven in many cases that the vast majority of these CLOWNS are well trained, well paid,
some are highly skilled, and they will often accuse you of the very "things" that they, themselves, are engaged in...
and they often work in groups while using numerious synms...

So be vigilant - it only takes one Clown to ruin a discussion or thread. Many good posters will not post or
simply leave once a Clown invades the thread.

Have a good day and happy posting...

I just thought, if we are an ordinary DC motor with permanent magnets, we will fix the rotor to the fixed support on one side on one support, and we will rotate the stator.
Then we will get a multi-phase sinusoidal signal on the fixed collector of this engine with a frequency proportional to the speed of rotation of the stator.
Which we can output with the help of wires to our Holcomb device under study.
I don’t know if you understood me, maybe you can’t do without a drawing ...

 Further to my "CLOWN - TROLL Exposure and What To Watch Out For" post above:

Since many of these Clown/Trolls are paid for posting and sometimes paid even more when you respond to their posts;
they can be quite persistant, as we have all seen, even to the point of being pesky. This is easily observed in many cases.

The best defence against this is to "Simply DO NO RESPOND" to them. Often times they will just "move on to another
thread" where they can gain a little more for their time and effort.

Clown Trolls can be a real problem, but exposing them and knowing how to mitigate their affect on a subject goes a long
way in combating this plague.
