BEMF current reversal.

[BroMikey]

Quote from Tinselkoala:

"A negative correlation has nothing to do with "negative Henry" nor does it imply that one or the other of the correlated variables is "negative". By posting what you have posted you reveal that you do not understand correlation or inverse relationships".

Tinselkoala can not find a correlation between the "Inverse Henry" term of magnetic reluctance, and the minus sign that appears before the number on the inductance meter when set to read in Henries. He always couples his misstatements with some kind of personal insult. (He's revealing his stupidity again) to help make his malarkey stick.

TK has been known to disagree with any extra energy thinking and is
stuck like so many on the conventional theories. I like what you say
Allen and you give a great explanation rather than doing what so many
other do, just one liner body slams. Your words are an alternative view
so many of us enjoy.

Stay cool and keep up the good work.

Allen specifically said meters. I have a very nice DSO. It will show a positive or negative current but only my training has taught me how to interpret that as a current direction. And Allen doesn't seem to believe the dozen or so scope shots he has been shown that clearly show NO reversal of current when the power is removed from an inductor.

Let's see some scope shots and meter readings to prove that theory. A video demonstrating this idea would be even better. Making up stuff is good for fairy tales but in the real world most of us want to see some proven facts demonstrated, not fantasy ideas.

@Citfa,

I'm awaiting service here in Costa Rica for calling you a liar. I'm doubling down on that insult.

We hope this can be resolved peacefully as it is against forum rules to insult other members here.

You've stated your case and probably can't add anything to your claims so if valid, should speak for themselves.

You did start this thread so you can request in your first post what topics you would like to cover and any disagreements can be made respectfully.

Clueless

Re: what is the physical meaning of "Negative Inductance"?

"The most fundamental reason is that the electric energy stored in this element is more than the magnetic energy stored. Circuit designers interpret it as a capacitor".

Here's what I've gathered: Increased inductor field strength creates a reluctance to changing current, but some current that fails to pass is stored in the inductor along with the magnetic field. Now, this is referred to as "Positive Capacitance" except the frequency reactance is reversed. The amount of positive capacitance in an inductor of charged magnetic field strength is measured in 'Negative Henries" of inductance, and has to be proportional to the intensity of the flux field.

Hi citfta,

I agree with your post which follows the one from Allen which I quoted above. It is sad how he misuses the terms and draws invalid conclusions. It's obvious to those familiar with the science that he doesn't have a clue. Must be his ego as to why he wastes opportunities to learn the facts and truth. His loss.

Law Suit

It is absolutely amazing how mixed up a person can get when they let their ego over-ride their common sense. All these silly things you keep bringing up Allen have already been explained to you over and over again but you keep insisting you are the only one right and everyone else is wrong. At least 10 different people have told you that you are not correct in your use of electronic terms, your are not correct in your understanding of basic algebra and you are not correct in your understanding of electronics. But your ego will not let you admit you might be wrong and everyone else correct. You can continue posting another thousand posts with you mistaken ideas and all you will accomplish is to prove to more and more people you don't have a clue what you are posting about. Instead of wasting all that time why don't you actually study some real electronics books or online classes and try to really learn something. The things you have learned from DumbTube or wherever have not helped you to understand electronics.

Negative Inductance.

bi basically explains how to properly read the formulas. This is important because if you can't, you're cleuless.

Granted bi's way of sharing his knowledge is not the best way of handling things socially. I am sure he means well though...

Thank you, I think.

@bistander,

You're telling us Ohms are not part of the resistance formula arithmetic. This amounts to nothing more then ridiculous crap and I'm getting fed up with it.

Not

@bistander,

Look again on the bottem left you'll see Reluctance times H-1. This means Reluctance multiplied by "Inverse Henries". Look at the right for the equivalent and you see Resistance multiplied by Ohms!

"Magnetic reluctance, or magnetic resistance, is a concept used in the analysis of magnetic circuits. It is analogous to resistance in an electrical circuit, but rather than dissipating electric energy it stores magnetic energy".

What are the units of stored magnetic energy?

The units are Teslas and Gauss! Therefore the (Reluctance is the product of the stored magnetic energy). The "Inverse Henry" is a measure of stored magnetic energy that factors into Tesla and Gauss.

The stored magnetic energy is similar to numbers of Ohms in the resistance formula. Both in brackets [ ].

@bistander,

This is at least the tenth time you made me repeat myself and I'm getting tired of it!

The tesla and the gauss are units of magnetic flux density or B field, not energy. The unit for energy is joule.

[Allen Burgess]

The characters inside the brackets [ and ] are the units, not variables or constants in the equation.

[Webers] are units of flux.

[A] are units of Ni. (or [amperes] are units of mmf, magnetomotive force, Ampere turns)

[H^-1] are units of reluctance. The unit for reluctance is the inverse henry.

The units are not part of the equation which is why they are set in the brackets [ and ]. The units are not part of the arithmetic.

@bistander,

You're telling us Ohms are not part of the resistance formula arithmetic. This amounts to nothing more then ridiculous crap and I'm getting fed up with it. You are now officially on my "Ignore List".

[bistander]

Confusing units still

@bystander,

Look again on the bottem left you'll see Reluctance =H-1.

The characters inside the brackets [ and ] are the units, not variables or constants in the equation.

[Webers] are units of flux.

[A] are units of Ni. (or [amperes] are units of mmf, magnetomotive force, Ampere turns)

[H^-1] are units of reluctance. The unit for reluctance is the inverse henry.

The units are not part of the equation which is why they are set in the brackets [ and ]. The units are not part of the arithmetic.

[ohms] are the units for R. It does not mean to multipy R times Omega.

[V] units for v. (or [volts] are the units for emf)

[A] units for i. (or [amperes] are the units for current)

[Allen Burgess]

You have circled around to where I came in yesterday; to the very proof you're wrong. The link is to the University of Colorado Boulder lecture displaying and explaing (teaching) this graphic:



See the red highlighted line of characters? That is the definition of reluctance. There is no dependence on magnetic force as you claim.

Dead Thread

Allen you burn thru people ....trying to find support for your vendetta against
a man who only tried to help you [one of many ]

most have not got a clue what you are actually talking about
perhaps you can teach here and leave out the finger pointing

if your argument has merit ...
it needs no screaming yelling or funny movies

it should be able to withstand investigation.
I would imagine a build to prove your....Whatsit

just one mans opinion

@ramset,

The moderators killed the bifilar thread not the commentators. You did this with culpable bias. TK kept complaining about my "Fake Deaf Sign Interpreter" video parodying him, while I had to tolerate a video posted by Tinman of me in a straight jacket as Louis the 14th. Who moderates the moderators?

The only thing Tinselkoala would offer to help with is rearranging furniture in a home for the blind.

[Allen Burgess]

BS

Pure BS. You can show no supporting theory or derivation, or find anyone in the world agreeing with you. Could it be you're wrong?
