BEMF current reversal.

A Pint is a pound the World around.

No it isn't! Some impudent smug snorts. No two things can be the same. We're constantly bombarded by such preposterous inanities.

A pint is equal to a pound in weight. 1 Coulomb is equal to 1 Gauss of magnetic force.

Negative values such as Henries of inductance or current in Ampere's have negative values on our measuring instruments we're forced to assign values to.

A negative Henry is a measure of magnetic force. Negative current is measured as equal to positive current simply moving backwards. These are positive values expressed in the negative range; Not imaginary terms.

Energy in an Inductor

"When power flows into an inductor, energy is stored in its magnetic field. When the current flowing through the inductor is increasing and di/dt becomes greater than zero, the instantaneous power in the circuit must also be greater than zero, ( P > 0 ) ie, positive which means that energy is being stored in the inductor.

Likewinse, if the current through the inductor is decreasing and di/dt is less than zero then the instantaneous power must also be less than zero, ( P < 0 ) ie, negative which means that the inductor is returning energy back into the circuit. Then by integrating the equation for power above, the total magnetic energy which is always positive, being stored in the inductor is therefore given as":

Here he is again restating the preposterous claim that Inverse is not Negative:

Nelson, I'm glad we agree on this basic algebra.

And now we are beginning to see where synchro has gone off the rails. He clearly doesn't get that the Inverse is not the Negative. X-1 is equal to 1/X, not some negative value. And the H (scalar unit of induction) of the Henry is not the same as the H (vector quantity)of the magnetizing field strength. He apparently has confused these two very different things in his mind, because of the use of the same letter for both. But the H of the field strength is a letter chosen at random by Lord Kelvin in 1850, and has nothing to do with the assignment of the name Henry and the letter H as abbreviation for the unit of inductance.

For Synchro: When letters are Bolded like that it is not done for emphasis. It is a common way to indicate that the quantity referred to is a _vector_ not a scalar. But I don't expect you to understand the difference, since the math is obviously over your head. You should however be capable of clearly understanding that the "H" of inductance is not the same thing as the "H" of magnetic field strength. Or am I giving you too much credit?




@Tinselkoala,

"A negative correlation means that there is an inverse relationship between two variables".


A quote from TK:


"has nothing to do with the assignment of the name Henry and the letter H as abbreviation for the unit of inductance"/


Definition from "Magnetic Reluctance":


"It's an SI derived unit it's the henry (the same as the unit of inductance), although the two concepts are distinct)".

I told him the negative Henry was a measure of a magnetic field, now he's trying to teach me my lesson back.

Pulsed &quot;Negative D.C. Current&quot;.

I've finally arrived at a description of 'Flyback Current Reversal" that everyone should agree on.

Thanks to Lawrence Tseung for his advice:

A Reed switch pulse motor would first close the contacts and pulse the coil with "Positive D.C. Current". Next, the Reed contacts would open, interrupting the current and causing the magnetic field to collapse. A "Negative D.C. Pulse" would then exit the coil in the same direction the "Positive Current" traveled. Connecting a reverse biased LED between the two coil electrodes would illuminate the LED flickeringly.

Tinselkoala's " Coil Current Direction when Power is Interrupted (2)" video contains the following "Slight of Hand" remark from TK in the video comment section:


"The fact that the Blue LED flashes, indicates that the current continues in the same direction through the coil as was flowing when powered. The fact that the Green LED does _not_ flash indicates that there is no reversed current hiding in there somewhere".

Naturally, everyone can see how the truth has once again been sneakily distorted by TK.

""I think there is only a magnetic field and an electric field, but no electromagnetic field. There is electromagnetic interaction tho. The creation of a magnetic field around a conductor is a sideeffect that by its own is for free, but when this field induces current flow externally (be it eddy currents, a coil, any ring...), this current flow causes the secondary magnetic fields, basicly following Lenzes law and counterinducing an opposite current flow, partially neutralizing the primary field."

I think you could have worded this better. Just saying.

@Doug1,

That's a quote from a comment made by member Dieter at the Overunity site. I agree with you that it could been wored better, but on forgiving Dieter, it's only fair to point out that English is just his second language.

@Citfa,

Why not jump Dieter's bones over at Overunity where you act like a moderator?

Eddy currents, being 1turn shortened coils, will basicly generate heat waste, as in induction cooking plates.


But iron, even tho passive, truely holds the key to various OU concepts, as it is a temporary magnet or magnetic vector deformer.


I myself use Iron to actually violate the law of conservation of energy. But you cannot simply plug a cord to it, it takes a bit more.


See my latest pdf in the files download section if you're interested in how I do that".

[Allen Burgess]

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.

Look at the stinking rubbish this fraud cooked up to condem the simple facts presented above!

[Allen Burgess]

"Let us consider another experiment. In Fig. 3 (below) a large wooden spool wound with a large number of turns of fine, insulated wire is connected to a galvanometer. A small spool wound with a few turns of insulated wire is connected in series with a dry cell and a contact key. Let us put the small spool down inside the large spool and press the contact key, closing the circuit. The galvanometer needle will be deflected, showing that a current has been induced in the large coil. What has happened? When we closed the switch and current started flowing in the small coil, that current caused a magnetic field to develop around it, and that developing magnetic field induced an emf and current in the large coil. If the key is kept closed, the induced current in the large coil soon stops. When the circuit is broken, the strength of the magnetic field quickly falls to zero and an induced current flowing in the opposite direction occurs. In both cases the induced current stops flowing when the magnetic field stops changing".

Faraday's induction:

"The direction of movement of the magnet altered the direction of the induced current, and similar results were achieved with the South pole of a magnet although the induced current was always opposite to current induced with the North pole of a magnet".

Viewing the two diagrams below demonstrates the correctness of the current reversal claims in each case. The movement of the primary field into and out of the secondary coil on the left causes the same current reversal as the magnet causes in the coils on the right when the magnet reverses direction.

Floyd Sweet's V.T.A.

Look at the nearly identical similarities between Skycollection's oscillating bifilar ferrite core transformer, and Floyd Sweets V.T.A.: "The exciter coil absorbs energy from the magnets in the BEMF". Floyd's exciter coil is connected to his output coil, and they're both oscillating at the self resonating frequency of the "Barium Ferrite" magnets.


"A resonant property is established to allow the exciter coil to absorb energy from the oscillating magnetic field from the barium magnets".

There's a strong chance Skycollection's transformer is 1.5 million times OU (like the V.T.A.) when it's self oscillating on the mildly magnetized ferrite cores alone, toward the end of his video, after he removes the neo spinner!

[Allen Burgess]

&quot;Negative Energy&quot; from ferrite core.

Here's "Skycollection's" latest video. Look at the power his BEMF's generating in a 12 volt bulb from a stack of ferrite core coils in oscillation:

https://www.youtube.com/watch?v=Ev-E84Mn_IY

Look at the large negative spike in Itseung's scope shot of the coil with the magnet inside below:

"Waveform for the case of magnet inside coil but the current was too small to make it jump. The DC Voltage was 4V. The Large Negative Voltage was observed".

Typically it is arbitrary. In circuit analysis you assign a direction to each current at the nodes. Typically one uses arrows on the schematic to represent these assigned current directions. Then when the actual values of the currents are calculated, if the assignment arrow was backwards, the numerical value will be negative.

Study Kirchoff's Laws of circuit analysis. KCL & KVL.

Well i would have to say its not arbitrary, you could dismiss it or ignore it if your not trying to truly understand whats really happening.
This is where the water analogy doesnt hold water (pun intended) 😁

Charge

We could have 6,241,500,000,000,000,000 electrons or many more in a state of stillness, paused, without an Intensity (understand as force, potency, power,etc) behind them effecting a specific pressure at a specific section (not closed, not looped) of a circuit...and how do you (and the rest of the world) call that.

Hi Ufo,

As usual, your question is not clear. So let's use a capacitor. I could connect that cap to a circuir and put a voltage across its terminals such that 2 Amperes flow and the cap is charged for one second. 2 Amps times 1 second equals 2 Ampere seconds abbreviated 2As. An Ampere second (As) is equal to a Coulomb of charge (C). Disconnect the capacitor after we charged it. It sits in a static state with 2C of charge or 12,843,000,000,000,000,000 electrons ready to discharge when a circuit is connected to the terminals such that current can flow.

Similarly batteries are defined by the charge they can store and deliver (independent of time). Normally battery charge is given in Ah (Ampere hours). One Ah = 3600C. Or one Ah = 22,469,400,000,000,000,000,000 electrons.
