@ minnie-or anyone else that cares to have a stab at it.

OK,lets see how your laws of induction skills go.

Below is a schematic and scope shot to go with the schematic.

L1 is wound on the former first-this is our primary coil.
L2 is wound over the top of L1.
The CVR is showing the current flowing through L1(the blue trace on the scope shot),and so this should be also indicating the rise of the magnetic field around L1. The current and voltage through and across L1 are extremely close to being in phase at these low frequencies
The yellow trace is showing the open voltage across L2.

Should L2s voltage trace be in phase with L1s current trace,of should it be 90* out of phase as shown in the scope shot?.

Please note the very low frequency being used,and the reason for that will become clearer later on.

#We are going to discuss your Libel of me in great detail elsewhere .[and you will take that to the Bank]

here however we stick to yet another ignorant remark of yours regarding magnets and what they are truly capable of.

see the 11 minute mark and beyond

https://www.youtube.com/watch?v=0PS2v1kN1U8

you place yourself here as the Urim and Thummim of all that your purvey.

Shame on you....

Brian Ahern was just pitching a "magic box" to try to raise money.  The clip is two years old and nothing has happened.  Somebody drove an electric car and the battery charged.  Sure.  Vibronic Energy Technologies Corp has no footprint at all online.  The CEO Curtis Firestone has no online footprint.  The only address I could find was for a house in MA.  So I don't see anything there at all except for a pitch from a two-person kitchen-table company.

@ MH

As requested.

https://www.google.ch/patents/US4969425

Good, so that patent shows a resonant cavity in the combustion chamber can be used to improve the performance of a two-stroke engine.  And you also put up a link showing how resonance in the cylinder of a typical four-stroke automobile engine reduces performance.  So there is no simple one-size-fits all answer and things have to be evaluated on a case-by-case basis.  So that one is a draw.

Shows how stupid you are.

No actually, it shows how stupid and ignorant you are.  A magnet does not dissipate energy.  Yet you state that a magnet does dissipate energy even though all evidence is to the contrary and just a simple level of understanding is all that is needed to see what is taking place and to arrive at the proper conclusion.

So you are the very definition of stupidity in this case.

And to parrot you, you have no idea what it is you are dealing with - you don't know what the magnetic force is, and so you cannot make the statement that you just tried to make.

You don't know what the "magnetic force" is Brad, you don't know what it is.

Well, take a neomag.  It takes a lot of energy to magnetize it right?  Then, over a period of time (I have heard 100-200 years) it loses its magnetic strength...so... if it is not dissipating that original energy...where is it?  Where did it go?  Or, what did that energy transform/convert into?

Everything should be considered with reasonableness and common sense and balance, don't you think?

When some of the magnetic alignments in a magnet spontaneously decay (increasing entropy) and the total magnetic energy stored in the magnet decreases then that lost energy is converted into heat.  Now of course that's Brad's cue to jump in and say, "See MileHigh is wrong again!"  But we are going to be reasonable and state that for all practical intents and purposes, a magnet does not "dissipate energy" as heat because in the real world it is not measurable.  It's just as crazy as claiming that your flashlight works by drawing energy from the Earth's magnetic field or that when you determine the top speed of a car you have to do it on a slope.  That kind of ridiculous nonsense is just what it is - ridiculous nonsense.

If we split hairs every single time we state something we end up going crazy.  I am not going to live in a nuthouse like that.

 I was going to get myself an osillyscope, but virtually no one on here knows
 how to use one- perhaps this is a more suitable toy.
 Junkie,you sure live up to your name....Junk.




Good Job John, 70+ years to learn that a Tractor of this type can do in 5 minutes what takes a single man all day - That’s Progress!!!


If you decide to get a Scope, TK wont be able to help you, he busted his and blamed in on the OEM, MilleHehehehe, he simply forgot about them all together is his fits of Dementia, not many others will be able to help as they all follow OEM Spec on how to use their scopes...

So no hope unless you need one as a Book End?

Keep up the good work old mate - You know, there is a saying:

You OU Pimpin Trolls do not, can not, and never can make an assumption like this!!!!

Making such assumptions is just a display of your total Arrogance in the eyes of all here!!!

You have no idea what so ever how a Magnet works, at all, period!!!

Lets see you prove this Arrogant Assumption!!!

Science is Real!!! Men/Women, hand shaking on something they do not know anything about, does NOT make it make it REAL!!! This is a Postulate! An assumption, simply, Fools that cant be bothered to get to the bottom of this Scientific Problem.

This Postulate came about to insure other Science Laws were upheld!

The Arrogance of you blokes is awesome to see!!!

No, it actually takes relatively little energy to magnetize a NdBFe magnet. And several magnet manufacturers have demonstrations where they place 2 strong magnets in opposition in a transparent tube and monitor the distance apart... and no change in that distance has happened over the years of the observation.
The energy put into magnetizing a magnet goes into aligning the tiny domains of the material. Over long periods of time, in a magnetically _soft_ material, some domains may re-randomize. This is not what is commonly referred to when we talk about "magnets dissipating energy".
But then I think you already know that, Bill.

Sounds like youre implying that Magnets and Atoms are Perpetual Motion Machines!!!

I hope not! You know what this means!

You're lying like the troll you are, Chris Sykes. And everyone here knows it.

STOP MISREPRESENTING MY WORK, stop lying, LEAVE ME OUT OF YOUR DEMENTED FANTASIES AND RIDICULOUS CLAIMS.



As far as the friend-funded Rigol DS1054z oscilloscope goes, and as anyone following my work knows, the First unit I received _definitely_ had a hardware fault from the factory and was replaced within days of my notifying Rigol and TEquipment. The Second unit I received worked fine, and I identified several SOFTWARE BUGS that were acknowledged by Rigol during the six months or so that I used it daily in my work. That scope had an early version of the Boot Loader software on it that caused the bugs. RIGOL THEMSELVES asked me if I wanted to trade out that scope for one with the _current_ Boot Loader, and I agreed to do so. They sent me the replacement completely free of charge, and sent it to me _before_ I sent the obsolete unit back, so I could test them side-by-side for several days, which I did, and which tests I reported to Rigol and on another forum where I sometimes post. So I am now using DAILY in my work the "Third" actual scope from Rigol. I've found a few bugs in the software of this scope as well, and have reported them to the appropriate places. The "average" user would never encounter most of these bugs in their daily basic scope use. For sure, EMJunkie would never see them, or even be able to tell when they hit.

It is a baldfaced and transparent lie that I "busted and blamed on the OEM" anything to do with my DS1054z. I have identified software faults in this complex and low-cost instrument, that are indeed due to oversights and poor programming on the part of the OEM. They are definitely NOT due to my "busting" anything, and my bug identification and reports are helping Rigol to improve their quality and service. The Rigol DS1054z remains the best oscilloscope value for the money (although the new Siglent scopes come close), and the few remaining bugs are not likely to be encountered by any but the most advanced scope users and can easily be worked around if they do crop up. Hopefully they will be fixed in the next firmware update and will no longer cause anyone any difficulty.

As always, I am happy to help (almost) anyone with understanding their instrumentation, with recommendations, and interpretation of what they see. The lying fool EMJunkie, however, can go spit.
