Magnets, motion and measurement

[norman6538]

I am amazed at how ungrateful some people are.  Floor has freely given you a lot of information he has collected by study and actual experiments.  No where have I seen where he suggested he was giving plans for a working device.  He is just freely sharing what he has learned.  It is up to those of us following his work to decide if we want to try and apply what he is FREELY sharing.  Please show some respect for his efforts.

Thanks,
Carroll I agree with you. I am a bencher and I have boxes and boxes of experiments that I did.
But today we have masses of keyboarders who know it all. I usually say "I don't understand" or
"I did this and these are my results" Without naming the person  I was banned from a group
because I asked questions. I lost all respect for that person - sure had a short fuse the made
a quick explosion.

I have a list of 15 or 20 names that I have great respect for and they do not flare up and call people
names.

Dear telecom,
sorry to chime in, you say you still do not understand how his shielding works and you are not convinced his ideas have merit.

This being the case, you either obtain some cheap ceramic magnets with the correct magnetic poles and start doing some tests or just abandon his ideas and step on to other designs. If you choose the tinkering way you get into the best position to figure out how one magnet can shield two others and what forces are involved and how to solve the mechanical requirements.  This is the only way for you to understand his setup. 
Once you understand, you can work from that point even to improve upon it and further develop. 

Happy New Year to you and yours.

To make long story short, I think magnetic shielding have some merits.
I made a simple contraption and it does appear that it can make a repulsive force much smaller.
See attached.
Happy new year to you as well, Gyula!

Thank you Telecom,  your last post / photos are a real contribution.

Not conclusive, but may have shown you that the concepts and designs have enough validity to merit a next step / build.

Some explanation...

A force does not expend and is not an expenditure of energy unless some thing is changed by that force......

Typically that change is described as motion, as a displacement along the direction of the force. 
                                        No motion = no work done and = no energy expended...

As an example consider.....   An auto mobile raised up, upon a lift.    Rotation of it's drive wheels has been completely locked.  The engine is running,
the manual transmission is engaged, but the clutch is not engaged.  Now the clutch is let out.  Once the clutch is engaged, no work / energy is expended by the engine.
Because its engine stops running.  No energy is then expended.   The engine must turn or there is no energy expended.  No motion = no work done and = no energy expended...

During the shielding magnet insertions and removals....  because of near balance between attraction and repulsion no work (nearly so) is done against magnetic forces....
Because forces are not present in the line / direction in which the shield is moved.

There ARE forces at right angles to those motions of the shielding magnet's insertion / removal.  But one does not fight them / and no work is done and no energy is expended
by or against or because of those forces.

This is because work = force times displacement.  If displacement = zero then energy expended also = zero....

There is an increase in friction upon the sliding  track system/s.  But even this increase, can be eliminated by dual / opposing systems.

One expends 1 joule of energy to lift a 102 gram sphere by 1 meter.  It requires no LIFTING ENERGY to move that 102 grams at a right angle to gravity's pull.
One then expends energy.....  only in accelerating that 102 gram sphere (side ways).  That expenditure is then,  only to over come friction  and / or inertia.
