The "MSJR" is an acronym for the "Mega Super Joule Ringer". Below I have schematics for Lasersaber's Joule Ringer 3, and Stafford's 3 battery system:

12 AA Energex rechargeable's wrapped bifilar and divided into 3 banks of 4 would permit us to replace the mechanical oscillator with a transistor and use Stafford's off the shelf switch system:

I can't seem to get anyone to understand what's going on with this thread topic. This is for ramset, TK and smOky2 :

Everyone can understand how the AA battery behaves like a ferrite core. I show an oscillator with 2 AA's in series attached to a 1" Neo magnet sphere and wrapped with a coil.

The inductance of the copper coil around the batteries with the magnet attached is lower then the inductance of the coil with no magnet attached. The Neo magnet sphere partially saturates the AA batteries and lowers the inductance of the coil. This is called "Negative Inductance".

Imagine we add additional magnets to the battery untill the inductance of the AA coil dropped to zero. We would read zero on the digital inductance meter right?

Let's say we add one more magnet. What happens to the reading on the inductance meter? It produces a negative value, because now the inductor core is past saturation and no longer a core but a weak magnet.

@Tinselkoala,

I know I got your attention over there on the SMOT thread. You discovered the "Inverse Henry" value in your research.

Now pay close attention because if you can't catch on to what I'm teaching you I'm going to throw the towel in on you for good.

You have run countless tests comparing the input fields between the serial bifilar and single wire coil and come up with no difference along with the old Milehigh who's uploading comments on this web site under a new alias.

The comparison needs to be between the serial bifilar's spontaneous field that accrues through self resonant oscillation and the input field in the single wire coil. This is no mystery and the comparison tests have been run by doctoral students at MIT for decades. You never understood their published results because you're not a physics major, you're an electrical engineer.

appologeeze for my ignorance of your terms or there application/implications on the Bench .
can you summarize  the benefit  of your claim in Layman's terms [Or MIT's claim Or ? ?
and perhaps link to one of your Videos that shows how you support this explanation/Claim ?


sincerely
Chet K
PS there are many here who cannot follow or are unaware of your claim, the words...Math and terms are not what I am
asking to understand


real world on the bench result /explanation showing the advantage, with an example of how you come to this conclusion?

PPS
Synchro
I see you posted a Vid below
to be fair I am Swamped in the Shop ATM and will dedicate some time tonight [as well as ask others for input
Much appreciated

@ramset,

View this video and I'll see if I can help you understand it if you have any questions:

Quickly looked at the Vid during lunch [not the whole thing yet]
I see it is a fellow who does not allow comments ...[many here consider that an issue or big red flag] and the experiment is in an area which really requires enormous understanding of all the possible variables [measurements and such]

the good news

 there is about to be a very extensive attempt to investigate a theory ,a theory based on solid scientific .....errr possibilities.. by several members here.
similar [vaguely] to the above video ....


and proper measurements will be at the very top of the To do list .

being sure that all input energy is accounted for and no erroneous assumptions are made such as environmental or background smog contributing to OUTput [unaware]

strict measurement protocols  are imperative in such experiments !!
and a daunting task to say the least.

is there no simpler "energy in ".. "energy out"  Video or claim you might offer for members to replicate here ?? to see or witness your claim?

a tesla coils is like a hurricane ...its reach and effects are hard to measure or qualify [with quality measurement protocols].
------------
On the upcoming experiments

many here are looking forward to this investigation ....

I am not certain where these upcoming experiments will happen as some builders here Chose to avoid the nonsensical attacks than can happen at this forum .....  plus attempts by other members who have never performed the experiments to posture themselves as specialists .

and then there are others who make all manner of assumptions based on terrible measurement protocols .

Not sure "yet" if your posted vid falls into the poor measurement  category ..
although I would imagine the upcoming tests will cover many assorted claims ..

no stone left unturned.

I SHOULD ADD

 there will certainly be a spot where these experiments will be shared here.

as this is an open source forum and the work is open source [the only kind of work to bother with IMO].

respectfully
Chet K

@ramset,

Thank you for helping pay serious attention to my problem. I'm only a little guy.

I'm getting excellent results dropping the inductance from a .320 mH inductor choke down to close to nothing with a ceramic magnet sandwich. I'll be uploading a video shortly.

O.K. I did it! Hooray! I'll wait for the morning to film and upload the video. I have a 10 loop thick uninsulated copper coil that measures .001 mH in the positive range with a small ferrite core, and in the negative range with the core removed with both the electrodes in place or reversed. This negative inductance reading indicates the presence of a minute magnetic field in the copper coil.


The .320 mH choke reduces to .050 mH with 4 ceramic magnets attached. I'll show both effects tomorrow.

@ramset,

Here's the video I promised. I hope this helps:

This video demonstrates the value of the "Inverse Henry".

Anyone remember Tinklecornola's Evostar's thread diatribe last year denying that the "Inverse Henry" was identical to the value measured by Synchro1's inductance meter in the video above?

Everyone can trust this crank to help explain "Flyback", right?

perhaps instead of remembering it would be better to explain /summarize the claim right here right now
and move forward not backward...


what does an inverse henry do on the bench that makes it valuable ?


not looking to Fight
Just understand


and it was Lunch break....

@ramset,

What I demonstrated in the video is a "Mag Amp". This kind of coil and variable ferrite core acts as a transistor base for magnetic current, not electrical.

Hi synchro,

I watched your video with interest but there is one question that I have.  Are you sure that your inductance meter is zeroed during this demo?  One simple way to tell is to short across the copper coil with a jumper while it is attached to the meter and see if the reading is still negative or actually goes to zero.

Regards,
Pm

@partzman,

Good point. The answer is yes, I shorted and reset the meter numerous times to double check the zero point. The important feature is that the negative and positive range value are in direct proportion to the position of the ferrite core relative to the zero line.
