A second form of induction known as "Maxwellian Induction" where a
changing electric field creates a magnetic field is also believed to
exist. This is related to the fabled "displacement current".
These two forms of induction are believed to be the result of the
ability of a changing magnetic field to create an electric field and
of a changing electric field to create a Magnetic field. Furthermore
it is widely accepted that the E field of induction is basically the
same E field as in electrostatic attraction or Coulomb's law.
Therefore equations can be derived by freely substituting these E
fields at will.
This leads to the calculation of induction through the use of "Flux
linkages". The number of "flux lines" that pass through a given
surface and the rate of change of them therefore determines the
induced emf. In modern form we'd calculate the surface integral of
the changing magnetic field over the loop in which the induction is
induced.
Hence it is widely believed that this "model" explains Induction
effects.
------------------
Unfortunately nearly all of the above ideas are utterly wrong.
Virtually ALL of the established explanations of Induction actually
make no sense whatever. Sorting it all out takes some work. Here are
the facts.
1. By reason of causality a changing electric field cannot create a
Magnetic field and a changing magnetic field cannot create an electric
field. In truth BOTH are created by a source current and once created
no longer interact with each other.
2. In spite of the nifty appearance of iron filings in a magnetic
field, "flux lines" is a bogus concept with no quantitative value.
Furthermore, 1 above proves that the use of the integral of a magnetic
field (Faraday's law) over a surface to find induced emf, while a
method that usually produces correct answers has no basis in the
physics of induction. The magnetic field cannot and does not "cause"
the E field of induction.
3. Maxwell induction and the displacement current have never been
demonstrated to exist and therefore have no experimental basis in
reality. Therefore we are reduced to having just Faraday Induction as
the ONLY form of induction.
4. Faraday induction exists only in non-moving systems and the Lorentz
force equation describes the case where things are in relative motion.
However it can be shown that the Lorentz forces are really just a case
of a transformation of reference frames from stationary to moving in
Faraday induction. It is the moving currents (charges) in moving
systems that create the induction fields. (See Jefimenko) Therefore,
non-moving Faraday induction is sufficient to describe ALL induction!
The Lorentz forces like "flux linkages" are merely mathematics that
give correct answers but have no REAL basis in the physics of the
situation.
5. Finally we must observe that the E field induced by changing
currents in Faraday Induction is NOT the same E field found in
electrostatic Coulomb attraction. It has different properties and
force directions. To blindly exchange these two E fields in equations
is clearly nonsense. A few researchers have made this point for a long
time.
6. We might also mention that the Vector Magnetic Potential, A, is
also non-causal to the induced emf of induction. This means that the
changing current to induced current effects of induction are operating
not through the intermediary of B or A and hence represent a current
to current mechanism that is NOT "explained".
The bottom line of all this is that the 'standard' Maxwellian
explanations and "model" of electromagnetic induction is completely in
error and any new "model" that might provide a "point of view" for the
current to current action of Faraday induction has not been
forthcoming. This therefore appears to be the current
"understanding" (or more exactly lack of it) of Electromagnetic
Induction and the physics that might lie behind it.
Let me thank all who responded to my recent thread. Even those who
responded with the wrong answers contributed because even arguing the
wrong things still causes one to rethink the whole issue to try to
prove what is "right" and what is "wrong". Hence the argument creates
the progress, while the various points made within it are merely
stepping stones to shaking out a better viewpoint! Thanks all.

Maybe we should cut the OP a break, because (no slight intended) but
it seems clear that he doesn't have a sufficient math background to
grasp Faradays law of induction or Maxwell's Equations, and
consequently doesn't understand the physics that they describe.
This seems reinforced by his constant citation to current carrying
conductors rather than tiime varying E fields or B fields.
Still, the enigma to me is this. Both of the cited articles contain
not only the mathematical description, but a text explanation
sufficiently clear enough to be grasped by a middle school level
student, so why doesn't he grasp the basic concept, or is it that he
doesn't want to? Is he perhaps a troll, because the quality of his
writing suggests that he isn't retarded and only pretending to be.
This is more or less a common signature of a troll.

Which means what? Are the form in which Maxwell's equations are
usually written causal? Sorry dumbass, they are not! They only show
that the right side of the equations EQUALS the left side. The right
side does NOT "cause" the left side or vice versa.
You know "Unc." unless you start to learn to think, you are never
going to amount to shit in science. A Handbook is filled with huge
amounts of data just like your photographic memory, and similarly
nobody ever saw a handbook develop any new theories on its own without
help.
You think simply repeating pat bumper sticker slogans over and over is
some kind of argument or debate? Just how ignorant are you?
<snip rest of "Unc. Al's" unthinking nonsense.>
Oh yeah.

Of course I do. Start with P.W. Bridgeman "the logic of modern
physics" 1928, then move on to "New horizons in Electric Magnetic and
Gravitational Field Theory" by W. J. Hooper, and finally get the
icing on the mathematical cake from Oleg Jefimenko "Causality,
Electromagnetic Induction and Gravitation".
But are you sure you'd really like to understand what I'm talking
about? Most of the replies here are by people whose idea of "research"
is to dig out their freshman class notes and look up and repeat what
the professor told them was "true". If faith isn't spoon-fed to them
they can't deal with it. You need to remember that although the

"went bad" after they got tenure, becoming insane "cranks" who started
publishing ideas that did not have the stamp of approval from

the braying crowd here and simply note that there is nothing that this
bunch of cranks could possibly say that might change your already made-

you certainly don't need to read any of their books to know that they

Eric, you know you can buy a course in reading comprehension that will

electrodynamic references, you "debunkers" have been listing nothing
but baseless charges and accusations that border on libel.
What are we doing here? Having a contest in who has the most
impressive library? OK. Lets make it real then. What was the last
electrodynamics textbook you PURCHASED (your own money is a
requirement here) and when?
Here's a hint Eric: We are not having a contest here about who has the
most abstruse books, nor who has taken the most advanced courses, or
who has the highest degrees or employment titles. We are having a
debate about IDEAS. If you and the other morons would like to join the
debate then you'll actually have to get down and dirty and start
discussing the things that are RELEVANT to those ideas. I'm sorry,
but "proof by assertion" only shows the person to be egotistical and
arrogant. "Proof by reputation" is only evidence that you stopped
doing any real work years ago, and an ad hominem attack, only
demonstrates that clearly you have nothing of value to add to the
subject in question.
I put the same question to you I put to Sue. Do you really enjoy

Yes Sue, those ARE the "intermediate values" in the Ewald method. That
is obvious. Which is exactly why I asked you to PROVIDE them not just
tell me the obvious. I suppose you thought I'd be snowed by your
little reference and have to go back to my Burger King mop once I
realized how much your brilliant brain could comprehend? You KNOW you
can't provide the coordinates I asked for, which means that your so-
called "ultimate proof" is nothing of the sort. It's a very limited
mathematical numerical approximation at best. The fact that it's the
"fastest computer in the world" means nothing in this discussion.

You need a new model. Many need because that made by Faraday, Ampere, Gauss,
Weber, Maxwell, Hertz, Jefimienko are not perfect.
It is time to come back to Aepinus (gravity and electrostatic are the same)
and Ampere (magnetism is an ilusion).
I see one model for all actions. Why you need the two different electric
actions?

Well, maybe not useless. Just useless for practical understanding.
It's still mathematics and it still stands on it's own as mathematics.
It's not that math is not an interesting and enlightening thing to
study, it's just that one needs to be aware that it is man-invented
systems and deep connections to "reality" have not been demonstrated
for it. But on the other hand people have recognized enough of an
analogy between maths and physical phenomena, that it does at times
become important in the mensuration of phenomena including useful
predictions of what physical systems might do before they are actually
built. The problems arise when people get too comfy with this and
start to look at the various philosophical systems of math as somehow
closer to ultimate reality than physical observations of reality.
Experiment is considered to be the "error" and math is taken to give
the "correct" answers. Needless to say that is upside down.
> You need a new model. Many need because that made by Faraday, Ampere, Gauss,
> Weber, Maxwell, Hertz, Jefimienko are not perfect.
I agree. Although it seems that Maxwell and Jefimenko have done the
most THINKING about things. Nevertheless there are problems. With
Maxwell it's the displacement thing, and I'm convinced that Jefimenko
somehow has his model backwards ( or you might say "reversed")
although I believe it is essentially correct in many ways. So yes,
while I've been presenting here what these gentlemen have said, my
personal view is that they are not yet perfect.
> It is time to come back to Aepinus (gravity and electrostatic are the same)
> and Ampere (magnetism is an ilusion).
This is a long-standing idea among many especially the "anti-gravity"
crowd. I do not agree with it. But I do agree that to understand the
nature of both gravity and electrostatic does require the addition of
a fourth or more dimension. Of course Jefimenko agrees with Ampere
that magnetism is an illusion, (non-causal) but this is where I
believe he is reversed. I believe magnetism to be the fundamental
phenomenon and not the current-current action at a distance of
induction that he promotes. .
> I see one model for all actions. Why you need the two different electric
> actions?
Because I see two different phenomena arising out of the properties of
the aether. So in a sense I'm talking about a SINGLE model which is an
aether model, but electrostatic forces and inductive forces are NOT
produced by the same aetheric phenomena IMHO. Two actions, two names.
That they both have been named 'electric fields" in the past has been
unfortunate because it created the temptation to mix them up
mathematically and substitute them around where they shouldn't have
been. That of course led to error. Even Jefimenko seems to fall into
this trap at times.

Many people want to write his own theory. It is like discusssion. But it is
nothing wrong to continue the old ones.
Now we know much more about ether waves. We are able to generate full
spectrum, from radio to X-rays. Here should be find all information about
eter.

It is a next new theory. Ampere made the artifical magnet (selenoid) and we
know that no magnetic monopoles.

-Hey, I love that Centipedal Field ring! I'm getting ready to build

I'm curious as to what the purpose is. To date i have only found one
mechanism remotely close to it and the ones building and prototyping it are
doing such for the anti gravity effect. www.ganid.com However their
mechanism is plauged with friction and has too few fields to interract with.
However they will reach the same limitations as any common mechanism given
the level of friction and the following. The drive system of their mechanism
is pulsed. Their mechanism is incapable of inducing energy in it's current
design.
-As I recall your

The field arrangement of my mechanism Superconducting Rotory Toroidal
Transformer,
SRTT for short is actually the toroid armature. The toroid armature is the
only moving part of the SRTT. The centipedal drive really is a simple
interaction between coil and arranged permanent magnetic fields. the toroid
armatures field arrangement is a ideal arrangement for driving multiple flux
fields through induction coils cyclic.

All the formulation in the world could never stumble across this. the main
problems are that physicists think singular or basic pairs and believe
everything is finite. The toroid armatures fields of the SRTT are in essence
duplicating the electron in a orbital path in a multiple arrangement with a
predetermined and controled path that does not allow entropy.
In short it is a closed system of transformations. The SRTT is the first and
only closed system to grace mankind with it's presence. however it may never
be realized unless it has some serious concideration by the scientific
community. I understand my methods of introduction are crude in the sense
that I cannot provide the formulation to back my claims.
however this doesnt take from the mechanics involved in this mechanism.
Mankind does not tell nature what to do. nature defines what mankind can do.
In reality all our vast knowledge is but a fraction of what is to be known
of nature.

And you didn't bother to respond to my question did you? What was the
last electromagnetic textbook you purchased with your own money and
what year was that? Well? Note that the text above (along with many
others) were purchased by me with my money. They were not
"complimentary freebies" or things I got my employer to buy for me.
So. Just how serious are you about electrodynamics?
