Here is a design for neutralizeing the magnetic force,
with an attraction based output.

These designs, devices and inventions are given into the public domiain.

note...since these are devices intended to give OU, one can reasonably assume they are
not previously pattented ?

Note...

I hve not put this last design (shielding with attraction as output) on the bench for testing yet.

Thanks for sharing these very clear drawings. I've seen the vid, which is impressive. Also in the light of Luc's latest measurements, very promesing.


I wonder how would you implement the work cycle in a rotor, or are you preferring a piston design (which would be much simpler I guess)?

Hi Dieter

         I'm still looking at the design @

http://overunity.com/17070/all-magnet-motor-td-based/

         I have some of the materials for a test build.
         
         I need to wet cut some ceramic magnets on
         the diamond wheel.
         
         Modify / cast some plastic gears (2 crown and 2 pinon gears)

         But for now I'll stick with the linear motion sets.
...     
                              my  projects

         Installing some flooring (paid project).

        I would like to do a full measurement set for Gotoluc's design (scaled down) ....
        before doing measurements of any of my new designs.   
                                               But first I'll need to ...
  detail / ask Luc to  check out  the magnet start and finish positions for that measurement process.

        There is yet another 3 magnet interaction set I want to diagram.
       
        I want to redo / finish the next section of the "Magnets Motion and Measurement"
        book / topic...... how to integrate a magnet force that is changing with distance and
        how to calculate the work done as joules and so on ................

                         regards

Too bad that magnetic lines of force cannot be actually shielded permanently, only guided. Temporarily it's possible to achieve everything, but you must be pretty fast - faster than the speed of EM wave spreading in material given.

If I were about to measure the forces, I would first build a vertical version, containing a track for the shield magnet, sliding on soap or teflon. So the shield can be dropped in from above. Then the shield could also be suspended on a thread, hanging downd from a balance, containing a counterweight, so the gravitational weight of the shield can be reduced to eg. a few grams. Will it slide trough? How much weight is required. Adjustable track, so the optimal arrangement can be found. The push force of the stacks could be measured over a pulley. How much weight can it lift for the same distance?


Something like that.


Experimenting with a reluctance swith, I have just learned that iron "conducts" magnetism much better than a permanent magnet. You would think a PM in a gap of a core is inxreasing the permeability, but actually the opposite happens, esp. with eg Ferrite PM. Seemingly the can transport only a rather low magnetic strength, maybe limited by their own PM strength, way below saturated iron that easily reaches 2 Tesla.

@ Zepher

I don't understand your statement.

Even a helmet struck with a base ball bat does not actually shield the wearer's head. The force is only guided,
      also  again
I don't understand your statement.
What does  faster have to do with this ?

That's some intetesting plans there, reads like a patent.


Of course, your test installation doesn't require my advice. When it comes to testing, I really use what's at hand, like wood, cardboard, glue and of course sticky tape. As long as it does the job.


But I wish I had the time, patience and resources to do that like in your pictures.

This is logical and it's how the magnetization curve of ferromagnetic materials works. The permanent magnet operates at the upper side of saturation curve, when the material already stops to behave ferromagnetically.

It's (hopefully) explained here up to some point.

I love the drawings and tested 2 of them but got some unexpected forces that
do not agree with the implications of the drawings and the video you posted
here http://www.dailymotion.com/video/x5eg7kk_magnetshield-1_tech

Anybody else have results to report?

@ Norman6538

Vague statements containing too little information (almost none and ....probably not even
10 % enough info) for me to really respond to, except.....

I'm not looking to play a masochistic / daddy role here.   I don't feel sorry for you! I don't belive
you need my help.  I'm not fond of  passive agressive / victim games.

I am totally doubtful that your    "tests"  (which are by the way, once again un-presented) have any where near to a
reasonable degree of  precision and / or are valid as tests.  Sorry but I have not     ever    seen 1 actual measurement
taken by    you and then presented     on this forum... ever.  Don't know that you haven't ever, but I see that,
once again you are stating that you have done measurements, but,  present neither the methods,  nor those
measurements.    Not good Norman...

This is what I keep objecting to   your doing   on my topics.   Hello ?
.....................
"but got some unexpected forces" 

Which / what forces ?  no description is given by you, why ?

not "expected" by who ? you ?
..................................................
Can you define "force"... with out looking it up ?

"that do not agree with the implications of the drawings and the video you posted"

great ?  I'm not asking for yours any ones "agreement"  with any "implications" that I quote "drew, posted, videoed"...

Do it well and do it your self  ...  and please go away.

@Floor, I ran it trough femm, this might be interesting. First image is with no shield (set to be air), second with shield according to drawings. Asymetry is weird, may be caused by asymetric surrounding air section. Probably just ignore it. Third picture shows approaching shield.


From what I see, there is indeed a tendency to create an area of low flux density. The reason why may be the high amount of field diffusion and superimposed compensation with the shield.

@Dieter

     I'm going to

1. measure the work done to slide the "force shielding magnet" INTO an in between the
repelling magnets position (an input), starting from a distance of around 1 1/2 inch away.

     note this will be done while the two repelling magnets are
          a.  at some distance from one another (that distance is undetermined at this time)
          b.  with the force shielding magnet centered between the repelling magnets.
                     (an input)

2. measure the work done in sliding the force shielding magnet FROM a position of
in between the repelling magnets, (while the repelling magnets are about 1/32 inch from the
force shielding magnet,  each on their side)...... removing the force shielding magnet  TO
about 1 1/2 inch away (an input)

3. measure the work done to bring the repelling magnets to close (1/32 inch each) proximity to
the force shielding magnet (an input)

           note this will be done while one of the repelling magnets is already in a close (1/32 inch)
proximity to the force shielding magnet.  Only one of the repelling magnets will be moved during this
measurement set.

4. measure the work done to close the gap between the repelling magnets, once the
force shielding magnet has been removed to its most distant position (an output
measured in reverse).
     note  this closure is to a distance of the width of the shielding magnet plus 2/32 inch.
             
              the starting width for this closure measurement is undetermined at this time.
