Magnet force shield

[Zephir]

I have just learned that iron "conducts" magnetism much better than a permanent magnet

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.

I don't understand your statement.

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

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 ?

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.

     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.
