Floor,


I spent a lot of time composing those comments you deleted. This is the last time I will ever post on any of your threads.

I'm working on a set of measurements for another topic. 

In the interum, here is a short video of magnets cyclically giving
a net gain in work out.

@ all readers

please note..
I have never built nor tested the input to output of the design in the previous post
                           "mirrorengine 9.pdf".

I have built and measured many of the designs presented earlier in this topic.

There are many good drawings / descriptions and videos, throughout the topic.

@ all readers
               also
I have been "informed" on very numerous occasions that "there is no such thing as a magnetic shield".

Please tell this to the Magnetic Shield Corporation, as they have been (apparently erroneously)
in the business of manufacturing and selling magnetic shielding for about 80 years.  Look em up !

What is shielding in general, and in specific what are some of the kinds of, and ways in which various kinds of shielding perform their function ?

Lets look at one type.

For many centuries, in some parts of the world, individuals have demonstrated a kind of shielding as performance art. It is as follows.  Performer #1 (typically of large stature and physical strength) lies on his back upon the ground.  A large / thick / broad / flat stone is placed upon his chest.  The stone typically has a weight of  some where around 80 or 100 pounds. 

While performer #1 holds the stone from rocking and / or sliding from its place, a second performer (performer #2) strikes the stone fiercely and repeatedly with a 6 or 8 pound sledge hammer, until the stone is split into two or more pieces.  Performer #1 is unharmed.

What is happening. 

1. We commonly say the stone has absorbed most of the impact, but this is a vagary. It gives no understanding of the how and why this works. 

The stone has a large mass as compared to the sledge hammer.  The kinetic energy of the lighter and fast moving sledge hammer is transformed into a slow moving / short distance travel, of the stone.

   In other words high speed / low mass, is traded for large mass slower speed and there fore less travel distance.

Upon the hammers striking of the stone, the kinetic energy in the hammer is transferred to the stone. The same kinetic energy that was present in the hammer is then present in the stone.  But that kinetic energy is also transformed in its ratio of mass to speed.  Greater mass with a lesser speed.  Lesser
speed over a given duration of the event, results in a lesser distance traveled by the stone, than would have been traveled by a stone of a mass equal to that of the sledge hammer.

2.  The energy present as the momentum of the sledge hammer is spread over the large surface area
of contact, between performer #1's chest and the stone.
                                           In other words the force is redistributed.
Is this over unity ?  No.

There are aspects other to and / or kinds of shielding, for example padding lengthens the time duration of an impact while also decreasing peak force.  Stretch / elasticity, when an object's fall is arrested by a rope  lengthens the time duration of an impact while also decreasing peak force and so on.
..............................................



continued

The magnetic force shielding methods presented have some characteristics in common with the sledge hammer and stone slab example.

The stone slab has a broad surface area against performer #1's chest, and a large amount of inertia due to its mass.  The force is DISTRIBUTED over a large area.

A force shielding magnet redirects various of the magnetic forces to act at right angles,  causing those force to be against the track or rail elements of the devices rather than against input energy / forces. 

The force is placed upon the sliding tracks.  It is DISTRIBUTED in such a manner that it cannot cause motion of the magnets.  No motion equals no kinetic energy transfer / expenditure.  But also the magnets can be moved along their tracks with out work against magnetic forces because those motions are at right angles to those magnetic forces.

The magnet force shielding differs in many and considerable ways from the stone and hammer example.  Rather than inertia acting in a major way, in the magnet interactions.  it is the interconnections of the magnets via the track elements of the devices which absorb, transform and limit the kinetic energy. This manifests as 90 degree change in direction of force and change in the ratio of force to displacement.

In other words the magnets are bound / limited in their motions to specific directions by the tracks, but also, the tracks are rigidly connected to each other. This rigid contentedness, in a manner of speaking, takes the place of  the inertia aspect of the stone slab / hammer example.

There is then also that aspect present in magnet interactions which is not at all present in the hammer / stone example.  Near balance of magnetic attraction with magnetic repulsion.  This aspect in combination with the force per distance transformations and force redirecting allows for a variety of very effective magnetic force neutralizations and shieldings. The results of which can be dramatic Over  Unity.

For a greater understanding of the subjects and if you wish, watch the videos or study the drawings.

            P.S.
             Magnetic energy is converted to mechanical energy, but
             there are no violations of physic's laws presented here.

The above design I call "MagnetShield1" 

Is a design  in which, when I came back to it / tried it again on my bench
several months after my first round of looking into it...
It didn't work out well, at all....

I thought I was either loosing my mind or...
something....

           I declared the design a bust / no go on this forum (another topic) at that
            point in time.  I even pulled the original video off line...

Turns out that my shielding magnet had radically altered itself in the interim time period
between my original examinations and that second much later, round of examinations
                          How ?

The shield magnet element of the design I used (still am using) was actually two magnets
that I glued together, edge to edge.   

Those magnets are wafer shaped and the poles are on the broad faces. 

When pressed together at their edges the two magnets could be oriented as either in
repulsion or as in attraction. 

Either a N to N and a S to S meeting at the edges or
a N to S and a  S to N meeting at the edges.

In this design, the shielding magnet is done out of two magnets edge to edge while
repelling each other ( N to N and S to S).

This was done not by intentional design, but rather because of improvisation.

I did not have a single magnet of the physical dimensions I needed.  So I combined
two magnets with glue.
 
I realize that this results in a field shape that is distorted into something other than
that shape which a single magnet will produce.  But I do not consider this as
having significantly impacted the out comes.

What did seriously impact those out comes, was the long time period during which
the two magnet remained glued to each other in repulsion.   

One of the magnets dominated the other and significantly weakened it.
This in turn totally wrecked the force balancing required for effective
redirection / neutralization of the magnet forces !

After figuring all that out,  I posted the original video on line again ( along time ago), but it is
at a different link (can't do anything about that).   And guess what.  It really does kick ass.

I just caught an error / omission in my postings early in this topic.

           was accidentally left out of that post...
           it is there now.
              Also
I Just now deleted a large number of posts from this topic. 
I am reorganizing this topic.
My goal is to be able to eventually present it as a coherent progression.
