Hi everyone, while i was playing about with my neo magnets in the attempt to try and create a perminant magnet on off flux switch, i discoverd something that i have also been playing around with several times.
I suppose you all have researched the MEG OU transformer and also tried to recreate a working model with no success like myself, the principle as far as i understand it uses a perminant magnet fixed to a ferus core and a coil also fixed to the core in a parallel arrangement, when i tried this arrangement, there was no way that i could turn on the coil enough to force the perminant magnets flux over to the coil to form a flux loupe.
Now while i was playing about with my magnets i placed one magnet onto a strip of iron, and checked with another strip of iron the edge of the now magnetised iron, and indeed the flux has traveled from the magnet to the iron edges and was magnetic, then i tried to stop the flux from travening to the iron edges by placing another magnet parallel next to the first one in a N/S arrangment, this did margingly reduce the flux on the iron edge but not enough to "switch" the magnetic flux off.
then i discoverd that if i place the second magnet on the other side of the iron, in a series arrangement, i then found that if the magnets are placed N/S against the iron, that the flux in the iron is zero! but if i place the magnets N/.N or S/S against the iron the flux strength is doubled!!
My next step was to wind an electro magnet to use as the second magnet, and after a few failed attempts with using wrong voltages or wrong amout of wire etc, i managed to create an electro magnet that seems to have simular strength to the perminant magnets i'm using.
so when placing the electro magnet (EM) onto the iron, i can now switch the perminant magnetic flux off by applying power to the EM, and if i reverse the polarity of the EM i gain twice as much flux in the iron!
I am thinking that this may work as an OU transformer if the iron has a coil winding around it too as in fig6 of my drawing.
Of course i may be totally wrong with this theory as im sure many of you are more knoledgable than i am, but just incase this is new to you, i thought ide let you know about my discovery (which is new to me!)
perhaps someone can think of a way of closing the flux loupe on my transformer design, i think it could be more efficiant if both sides of the input coils and magnets were utilised in my drawing they are open ended, but the secondary coil is a toroid closed loupe.
let me know your oppinions thanks
Fred
Hi Fred,
Thanks for sharing your ideas. You must have reinvented it, sorry to make this a rainy day for you...
First I saw this kind of setup at Naudin site: http://jnaudin.free.fr/html/mep1.htm
And also I saw it referred to somewhere in the net from the Bearden book, referenced to Bedini and Bearden they said it can be overunity.
So I hope you are not discouraged and keep improving it and test, test and test!

I am not sure if it will work, I will try to explain why my word:
If the electro magnet is OFF, the output coil already receive 50% of the power from the magnet, now you apply
the input coil, the other 50% is added to give 100%, the output receive 2 times more but when the input coil is OFF
its return back to 50%, so the wave is still only from 50 to 100, not from 0 to 100, that mean you get the
exact same amount of power from the output coil you put in, the only way to get 2 times is to pulse the coil from N then S, not N and OFF. But by doing that you cannot get overunity.
Hopefully someone will understand what I am trying to say :)
Ha I just got an idea to maybe overcome the problem I described. We just need to use the 2 sides of the input coil, so you have a metal piece/magnet on N and one on S, so when switching pole, one of the 2 output coil will receive a true wave from 0 to 100% not from 50 to 100%.
very easy to understand it
if you make an cascade from 2 or 4 magnets.
and stapel it NS-NS so is the maximal magnetforces on both "oudside" ends.!!
In the "mid" is nothing ! no flux ! Its an neutral zone !!
So als wit 4 magnets!
I you have an magnet rood example 10 cm , in the mid is no
magnetic forces, BUT if you "break" or cut this in the mid.
than you have 2 fully magnets, with EACH fully flux on both ends.
---------------------
I seen. some Computer-Loudspeakers are constructed the new way.
An second magnet-ring is stapled on the existing (from normal constructed Speaker.
That make the field forces stronger , ANF the hold all magnet flux-lines (forces) near
to the magnet, so it can not irritate the deflection from CRT Color Monitor it the speaker stand
near by them. This "device i seen now one time only. (In my repair work-shop), It was an chinese product .. an it wonder me .. for this new "idea"
(If second magnet will fixed in invers way. The Speaker must work with lot of "losses").
To do construction like youirs with One electro-magnet as second force
is fine because you can vary the magnetism. ALSO no perm , with 2 Electromagnets
you will also think about this possibility ! Than you have an endless new range of ideas, that you can use this.
Nice work to (for) you

Hi,
Well, I think you are "almost" right, however if we assume normal soft iron core for the electromagnet then the 50% will be reduced to much less % so the available flux change will be higher than you propose.
This problem could be fully solved I think by using Jack Hildenbrand's magnetic valve in place of the permanent magnet ;) because his valve's permanent magnet flux is closed right at the place where the valve is placed to a iron piece, it will not reach/extend towards the other end when its control coil is off.
I remember now a forum member here already presented a mechanical solution for this same idea, I found it, see here:
http://www.overunity.com/index.php/topic,309.msg1927.html#msg1927
If you click on the picture, you can see the animation on the principle. (unfortunately m668004 is not a member here any more...)
So this setup still seems a very good idea and really deserves testing/refining it.

Its nice to learn that my playing around has come to something positive, even though it has been spoken about before!
what is the Jack Hildenbrand's magnetic valve? this sounds interesting, is it a way of switching off the flux of a perminant magnet?
is there a link to the drawings and description to this magnetic valve? i'de like to learn more about it.

Here the image of what I am talking, its probably better to use the 2 sides instead of one

Hi Fred,
Yes, there is a link to Jack's valve, see this link and the valve's principle is in a picture about down in the middle:
http://peswiki.com/index.php/Director:Hilden-Brand_Electromagnet_Motor
By the way Jack is also a member here as JackH and there are two threads on his motors/controllers but unfortunately he deleted all his important explanations on his valves/motors last year probably due to patenting issues?
Keep up good work!

If its a fact that using both ends of the coils and the magnets will increase efficiency, i have just sketched a drawing of a way this could be constructed (very crude drawing!) i have thought about getting two toroid cores and cutting one in half for the primary windings (as in my drawing) and placing 4 windings on the whole toriod, as the secondary windings, with the "half moon" shaped cores butted up against the top of the whole toroid between the 4 coils, and then placing 4 magnets under the toroid directly oppersite the half moon core ends, and placing an iron bar between the magnets on their open ends to complete the magnetic circuit.
could this solve the 50% problem and make it 100% as stated in the post above?
my main problem is that i dont have the correct tools to cut a toroid core!
is anyone willing to try this?
this design uses both sides of both coils, could this work?

Hi Fred,
You do not neccessarily need to cut up toroid cores, there are off the shelf U shaped ferrite (or laminated) cores like you can see here: http://www.magnet-tech.com/core/MnZn/mnzn_power_ferrite/UF_UI.htm IF you have old computer monitor or old television receiver in the cellar, the line output transformer in them (which makes the high voltage for the CRT) has two U shaped cores for instance.
Your last but one drawing seems good for me, the only concern could be the polarities of the switched fluxes that enter into the toroid core and are expected to induce voltage/current in the coils may work against each other if one is not careful and this may decrease output.
Regarding your last drawing with the U shape core, I do not like it as much because the electromagnet connecting the the endings of the U core may constitute a closed magnetic circuit with the output coil in the middle of the U core (such setup may work also as a conventional transformer, input and output flux path is common, this not really wanted in setups you expect ou from).
Have you noticed this video on the Hildebrand thread? Very good test we can learn from it. See here: http://www.overunity.com/index.php/topic,2386.msg100361.html#msg100361
