Hi Jimbo,

The concept of embedding a permanent magnet into a ferromagnetic enclosure and use a coil to control the setup was also proposed by Jack Hildenbrand, see his drawings in his thread here: 
 https://overunity.com/833/hilden-brand-magnet-motor/msg22925/#msg22925 

He built several motors with his concept, you can see some pictures on motors he uploaded in his thread but later he deleted them all (mainly due to the patenting process) and someone from the members here saved some of them in this site:
 http://purco.qc.ca/ftp/Inventors/Jack-W-Hildenbrand/   
In the folder you can see a video on a test demonstrating the Hildenbrand valve principle, done by another kind member here back then.   

Jack patented the concept as "System and method for utilizing magnetic energy", US7453341, the pdf file is also included in the folder.   He claimed a COP of around 2 (to 2.5) for his motors based on the concept https://overunity.com/833/hilden-brand-magnet-motor/msg23790/#msg23790 
(COP = Coefficient of Performance).  Unfortunately Jack deceased in an illness soon after he got the patent and, as I know, no successful replications have been done ever since to get COP > 1 with the concept. 

There was another member here, DMMPOWER, who showed a drawing on the concept as a "super" electromagnet, see here: 
 https://overunity.com/4624/how-to-make-bedini-motor-overunity/msg96814/#msg96814 

And see Floor's post with a link included in it:
https://overunity.com/13354/perm-magnet-only-core-with-iron-shell-motor-coil/msg563135/#msg563135  and see the start of the thread here:
https://overunity.com/13354/perm-magnet-only-core-with-iron-shell-motor-coil/msg354318/#msg354318       

Please do not misunderstand my mentioning the above examples, your efforts and enthusiasm are appreciated and please continue tinkering with this concept.

Here's a drawing

This is what Jimbo is referring to... I made this a bit back but haven't finished it yet. Just needs the wire wrapped on it. It's 1 of about 20 ideas bouncing in my head I need to work with and learn more about. I'll get this one wrapped and do some tests real quick. I want to test this pretty heavily as well a little twist I have planned. I'll share as I go.

Yes this has a history but new to me I'm trying to come up with a motor with hardware store parts .so far I've settled on steel pipes as rotors and the shell over the magnets .I've got a lot of high strength ferrite magnets from a long time ago .I'm going to stack them inside the pipe and cut 45deg ends and go on a 90deg angle to the rotors .its interesting that this might be scalable .I need more parts ...I've course ..I'm also going to make a fan out of this .for personal use .I was thinking that what might happen if it was apposing solenoids  each with 1 to 4 would that in repulsion mod be 2 to 8 ?. Or as a solenoid motor with a neo core piston and a iron shell wrapped neo .it would be pulled in on no power and go out half way on full power so you would need a coil with a centertap and fire that to get it out the rest of the stroke.there would be no dead stroke. And 1to 4 out with a pull back in stroke . might be a simpler motor.and 4 times the power for the same energy.  I'd like to see just how much comes out and if it will run several more units asking for four more units would be hard to believe. I saw a guy using this with a old transformer getting more out as electrical power then in .it pluses positive only . to much information over load .got to rest my mind . if the pipes work out ..and I don't see why not ..you could just fill up pipes or stack up magnets and rap the pipe very simple. Not need for machining just a hack saw and drill.

Since we are talking about making a coil that is much stronger than a normal coil I wondered how hard it would be to make a gauss meter.  They are pretty expensive if you buy one but very cheap if you are willing to make your own.  Of course they won't be calibrated but would be good for relative measurements.  I found this article on line for anyone interested in making their own;

Clarification of intent / approaches / design and some possibilities ?

We have concepts and / or designs,  wherein the intent is to
                                   suppress
a permanent magnet by means of the application of an opposing
electromagnet.  This is already being used in scrap metal lifting cranes
and so on.  No    direct    net gain here.
... ... ... ... ...
We have concepts and / or designs,  wherein the intent is to
                                      shunt
magnetic force in such a manner that the process of the
        cyclical, shunting and / or switching of that magnetic current from
shunted to un shunted,
                           will consume less energy than can be gained from
the energy difference between the application of that force when shunted and un - shunted.
... ... ... ... ...
We have concepts and / or designs,  wherein the intent is to
                                            balance forces
                 such that force vectors and / or other characteristics
              may be rearranged without a net opposition by magnetic forces
                                               and in turn
              those rearrangements give rise to  interactions which are profitable
                                      in terms of an energy gain.

... ... ... ... ...
We have concepts and / or designs,  wherein the intent is to
         stall or slow down in time / create some form of stasis in an event
                                     during which period we
                                     move a field or exit it,
                                                     or
                       in some other way alter some relationship/s
     such that force vectors and / or other characteristics may be rearranged without
                                                or with little
             significant opposition and there by profit, in term of an energy gain.
... ... ... ... ...
                  We have concepts and / or designs,  wherein the intent is
                   multiplications or additions (cascading) of force where in
                                                          there exits
                                                    no   apparent  gain,
                              because increases must be reversed or undone
                                             in order to proceed cyclically.
                                                                but
                      those forces can while in their multiplied state / conditions
                                                  give rise to changes
               which do not subtract from the energy used to cause reversal / undoing
                                                          and instead
                      only cause a delay in time in the macro world, of that reversal / undoing
                                   (apparently simultaneous to that reversal / undoing)
                                                              behavior
                               (which is  in some manner is like unto the behaviors
                                        of those, theorized, particles, which physics
                                                          has termed virtual).
... ... ... ... ...

                                              Some combinations of the above.

                                              Some of the above may be statements of
                                              essentially the same things.

                                              Other options.

Flynn if your concerned about output check out Flynn magnetic motor he's got a industry built around it .and in his diagrams its 1 in  and 4 out .

floor what are you taking about ?

There are several methods of approach in regard to electro permanent magnet interactions.

No doubt.  In some conditions the combination of an electromagnet and a
permanent magnet will      increase         the magnetic force from the magnet.
They add up.

No doubt.  In some conditions the combination of an electromagnet and a
permanent magnet will       decrease      the magnetic force from the magnet.
They subtract.

There are other things that one might hope to accomplish.

for example...
 
The turning on and off of a magnetic current, by a method which might in some
ways be like unto the way a transistor can turn on or off an electric current.
I refer to this as      shunting      the magnetic current into another path or as
simply  shunting.

Some transistors use an extremely low amount of power to do that switching.

If a permanent magnet can be switched in that way, this would be free energy from
that magnet.


There are other approaches to the goal of gaining energy as well. 
Some of them, I listed above.


It is good to have some idea as to which approach one is using,
as well as why it might work.
No ?

How would you define the approach which you are using ?

   hoping for your success
