Magnetic field of a bifilar pancake coil

[Allen Burgess]

You can see the factor in the equation below:


"The Mystery of Inductance of Lead Wire We sometimes see "inductance of lead wire" in Electrical Engineering technical books. For example, the expression below is found in a book titled "Analytical Noise Mechanism" by CQ Publishing Co. at its 120th page".

L = 2*l*(log(4*l/d)-3/4) (nH/m) (1)

where, L = inductance of lead wire (nH/m)
d = diameter of lead wire (cm)
l = length of lead wire (cm)

So what?

@bistander,

Can you provide us with "Hyperlinks" to any of these so-called sources of yours with specific facts pertaining to the particular values under discussion?

@bistander,

Nice copy and paste job. So what?

So what? I did what you requested. Provided a link and copy-paste for your added convenience. Can you not read the formal universally accepted definitions for coulomb, gauss, watt and tesla? Do any of those appear equivalent?

@bistander,

First you told me I had a crappy Inductance meter. Now you're telling me I need to go back to kindergarten? When are you going to knock the wise guy routine off?

Here's the equivilency:

"The SI base unit for electric current is the ampere. 1 ampere is equal to 1 coulomb/second, or 2997924536.84 electrons per Gauss".

[Allen Burgess]

The High mind is in direct opposition to the experiment. Allen you are
an experimenter and are pointing out many things I like. Keep at it,
that is by repeating what you know so I can finally see this.

One thing I can tell you after being a public speaker for 40 years is
that the more you repeat a matter, the more refined your delivery
becomes. It is not as easy as you may think.

Frustration, slights and en undoes are incoming fire that stems from
being shot at by other high minds. Contamination. Don't let it disturb
your continuity. This is a war.

Thanks for presenting your view outside the box
Endless equations won't take us out there.

@BroMickey,

Thank you for your reassuring words. This is an extremely esoteric area of electronics. This is one of the few places the measurements I'm defining have any practical value. The bifilar gain is measured in units of negative inductance. Otherwise, we would never encounter the measurement.

I'm asking Tinman to measure his bifilar col inductance while under power and to take notice of the minus sign that should appear before his Henry value. We will be able to calculate the same gain in amperage this way, as a double check, without the oscilloscope.

"The SI base unit for electric current is the ampere. 1 ampere is equal to 1 coulomb/second, or 2997924536.84 gauss".

So you just claimed one ampere is equal to 100 times the highest magnetic field mankind has ever been able to produce on this planet or a level approaching the flux density on the surface of a neutron star.

The "C" on that chart is the abbreviation for Coulomb, the unit of electric charge, not the speed of light.

@bistander,

You're just a crank. Shut up!

[bistander]

Complex

@bistander,

Quote from bistander:

"The experimenter needs to use impedances with complex arithmetic for the circuit and power calculations".

We need bystander to confuse us with calculations that are too hard for him to deal with.

Look how simple this really is:

"Definitions. In both AC and DC fields, the reluctance is the ratio of the "magnetomotive force” (MMF) in a magnetic circuit to the magnetic flux in this circuit".

In this context, complex does not mean difficult. The experiment used AC in the circuit therefore the analysis requires the use of impedance. This article explains the method. https://en.m.wikipedia.org/wiki/Elec...plex_impedance. BTW, reluctance isn't even mentioned in the article.

Look how simple this really is:

Yes Allen, it is really simple to get wrong answers.

Allen and Bro Mikey
I think you two just want to fight ??
seems you like to fight ??

who said we take one mans build as Gospel??

Here as always there will be many fellows building
and []as always Brutal honesty will rule the day.

there are no claims [yet] just hunches.. well founded hunches[MEI work]

and I honestly have no idea what Allen is writing ...he seems to be mixing many things up.
and to be perfectly honest after all these years of reading these nonsense fights....

seems that's what this is really all about...fighting just because Allen Likes fighting, if he put 1 percent of the effort he puts into fighting into one well explained experiment he would probably save another ten years of useless fighting

enuff already
start a fighting thread, I'll sell tickets

as the admin stated to Allen a few days ago [RE His endless fights here]

prove it !! your work should stand alone...as an example of your claims.
--------------------------------------------

you want to set an example here ? Do it ....stop fighting with shadows

show what you mean on the bench

enuff of this shadow boxing and cluttering this mans thread
yeesh

@bistander,

That's electrons.

I explained the Coulomb to Gauss is equivalent to Energy times the speed of light squared.

@ramset,

You're like a dog returning to his own puke.

You wrote so many lies in the first sentence ,I could not read the rest

JUST One

please don't print lies here, there is enuff confusion already?

One example of your claim above about Me??

just one

you'll be looking for a long time...I don't do fights

PS to Allen below
Seems Admin doesn't like fights here either ...snitching is an Odd word to use in regards to following house rules

I would have called that "respect" just like respecting a mans thread,

@ramset,

You used the admin word! What right do you have to act as a "snitch" over here?

[Allen Burgess]

E=MC squared.

@bistander,

The number of electrons that it takes to generate a Gauss of magnetic force are equivalent to the ratio of energy in a unit of mass.

Oersted and Gauss determined the proportion of Albert Einstein's special theory of relativity; Energy equals mass times the speed of light squared.

Magnetism is mass.

THEY TOOK MY EYE OUT OF MY HEAD LAST WEEK SEWED A FEW DOZEN STISTCHED AROUND AND EMPTIED ALL THE FLUID OUT AND FILLED IT WITH OIL

YEAH
ITS REALLY HARD TO READ BECAUSE EVERYTHING THE GOOD EYE DOES IT MAKES THE SORE EYE MOVE AND HURTS LIKE HELL

Now I look up and see all big print

Yeesh

Im not writing it over

and I'm leaving for a few hours

Just one Bro
just one
In the meantime
here is a link to some work[beginning of MEI stuff
Investigating "anomalies" in Bifilar coils

I will open a dedicated thread here once the real experiment from Partzman gets shipped

sorry to Evo for the noise

House rules.

@ramset,

You're the extra "House Rules" cop, huh?
