I said the magnetic field of a pancake coil,would be the same as that of a ring magnet-and it would be.

Just work it out in your head and get it right.

@Tinselkoala,

So you're quoting Citfa for authority now?


He is certainly a lot more of an authority than YOU claim to be.


Quote

"A flux density of one Wb/m2 (one weber per square metre) is one tesla".

"Henry (H). Henry is the unit of inductance. 1H = 1Wb / 1A ... One ampere-hour is equal to 3600 coulombs".

Here's a question for you: How much magnetic strength will one ampere-hour of current generate in an inductor of one Henry of inductance?


I've got some news for you, genius. The Ampere-hour is not a measure of CURRENT.
Figure it out: An Ampere is a Coulomb of charge per second. So the units of the Ampere-hour are (Coulombs/second) x 60 seconds per minute x 60 minutes per hour = 3600 Coulombs. The Ampere-Hour is a measure of CHARGE.


See the wiki if you don't believe me. Units are important! At least to people who actually understand them.

What I wanted to try with a bifi pancake is put some maple syrup on it and eat it. ;D

In Teslas transmitter and receiver pat drawing, it shows what 'really' looks like each having a pancake coil 'with' a low number turn winding, 2 turns in the drawing as I remember, around the outer perimeter of the pancake winding, of which I believe the outer 2 turn winding is a primary in the transmitter and it is a secondary in the receiver. So if like the drawing, of which was depicted as such in comparison to many coils shown otherwise in his other works, the 2 turn outer winding seems like it was most certainly placed there so the 2 windings would have the best mutual induction, wouldnt ya think? ???

So maybe instead of just messing with a pancake coil to see what it does in comparison to others on its own, give the outer winding a whack and make it movable to see if it is on the same plain as the bifi if that gives best mutual induction, and try it both ways, like it were a transformer and see what ya get. Just wonder if it would be the same ole same ole just like a regular transformer, or maybe not. No core. maybe it is better than a cylindrical air core. maybe not.

But there must be a special purpose for a pancake coil, otherwise why take pics of yourself sitting in a chair in front of one. ;)

And if the 2 turn coils position on the outer perimeter of the pancake is the best for mutual induction, then what does that say about the pancakes field in comparison to other coils or magnets?

Contrary to what the resident authorities continue to shove down the throats of those who will not do their due diligence, there is something special about the bifilar coil.

Right, it's the familiar story.  "There is 'something special' about the bifilar coil but I will not say what it is."  Isn't that the essence of what you are saying?

Please, go ahead and state exactly what is special about the bifilar coil and how you can apply that to accomplish something practical in the real world.  Just go ahead and say it.

Neither of these wonders have seen the light of day, it's up to us to rediscover them. 

And this is the same old self-flagellation pitch.  You are not worthy!   I am NOT going to tell you how it works.  It's a mystery that YOU must figure out for yourself.  Why should "we" share information with the likes of YOU? 

Sorry, but I think the sarcasm is justified because I have seen you and many others on this forum scold people for simply asking for the alleged information.

@Mags: Sometimes the "best" mutual induction is not the "greatest" mutual induction. Rather loose coupling is required for better performance of certain (ahem) air core quarter-wave resonant transformer systems that take advantage of VRSWR.

Note the very specific claims in this video by TheOldScientist about the _DC Resistance_  and the _Inductance_ of the single layer Tesla Bifilar solenoid coil he tests in comparison to the single layer monofilar coil with the same amount of wire. And note that he does not allow comments on this video.

I'll have more to say about this, once people have watched and commented here about these specific measurements made by TOS.

Please continue this argument by yourself.  I have no use for you, nor your opinions.

There is a difference between asking a question and expressing an opinion. Why don't you just answer the questions that have been asked?

I know why, and you do too.

Dear All.

I have attached a pdf file from 2011.

Now before you all start lining up with the " butcher knives " did anyone, anywhere try this?

Wouldn't it be an interesting project to prove practically?

Cheers Graham.

@Tinselkoala,

Now you're outsmarting everyone again as a big genius on some technicality when you stated repeatedly that the Tesla and Henry
were like apples and eggs. You never understood anything about inductance the entire time. You proved that by your comments. No one's willing to use you any longer to teach here at the Overunity site. It's too late. Youv've been exposed as a fake for all time. 

That's not your only area of complete ignorance: You challenge the vortex PHI theory of Electro Gravitation, and apply Square exponent "Frequency Spectrum" math to spiral 1.618 ratios of magnetism. You challenge the "Unified Field Theory" and on top of that you're a "copy and paste" addict who covers his ignorance with insults and abuse. 

You want me to discuss the units of charge, implying that I'm the one who has no understanding of inductance, while you continue to confuse everybody.

An Inductor with a measured inductance of 1 Henry will generate a magnetic field if 1 Tesla in flux density with a fixed current input. Now you pretend you are better to determine what that factor is than I am after quoting things from Citfa like Henries are bananas not monkeys and reams of other utterly ridiculous things.

Now that I towed you and your "Lug of Nuts" this far, go ahead and tell us just exactly how much current it would take to generate 1 Tesla of magnetic flux in an inductor of 1 Henry of measured inductance. Pray tell us now Mr. I.Q.!

Don't accuse Synchro1 of "Flipping the Drag Bail" on you for continued play. Everyone knows as you say: "How important these units are"!

@Tinselkoala,

Here's something to help:

1.- "The basic unit of measurement for inductance is called the Henry, ( H ) after Joseph Henry, but it also has the units of 
Webers per Ampere ( 1 H = 1 Wb/A )".


1a.- "An ampere is a coulomb of charge per second".

2a.- "The weber /ˈweɪbər/ (symbol: Wb) is the SI unit of magnetic flux. A flux density of one Wb/m2 is one tesla".

@Tinselkoala,

Still waiting for your reply. Here's more help:

A Kilowatt of power collected in a bank of storage batteries would accumulate into a given charge. An Ampere hour of power fed into an inductor would be stored in a magnetic flux field and add up to a charge.

Are you having some kind of meltdown synchro?

An Amp-hour is NOT A MEASURE OF POWER. An Amp-Hour is NOT A MEASURE OF CURRENT.

The Henry and the Tesla are NOT EQUIVALENT, even if you put a minus sign in front of the Henry.

It is very clear that your words mean whatever you think they mean when you use them, not what they ACTUALLY mean. And you change what you think they mean whenever you finally get around to looking up the words you use in some kind of dictionary.

Your own words:
Quote
An Ampere hour of power fed into an inductor would be stored in a magnetic flux field and add up to a charge.
Quote
A negative Henry is the equivalent of one Tesla of magnetic strength. Both have positive values.
Quote
How much magnetic strength will one ampere-hour of current generate in an inductor of one Henry of inductance?
Quote
2.- One Tesla of magnetic strength in an inductor of one Henry of Inductance with one ampere-hour of current flowing through it reads as one negative Henry on the inductance meter. The minus sign indicates the level of magnetic strength. The inductance meter in the negative value acts as a gauss meter.


It is utterly impossible to have any kind of rational discussion with you because YOU DON'T KNOW WHAT YOU ARE TALKING ABOUT.

@Tinselkoala,

What's the answer to the question I asked you; How much electrical power would it take to generate 1 Tesla of magnetic flux in an inductor coil of 1 Henry of measured inductance?
