The device can of course be oriented so that the
shield magnet's motion is at 90 degrees to gravity.

Also build and test / measure the Lumen and / or

This variation of MagnetForceShield 2, has a good output
magnet displacement length
but also
an exceptional capacity / distance of attracting the output
magnet back to start position, once the shield magnet has
been restored !
But
Shield insertion and removal require a lot of work input and I don't know /
have not measured the total in to out ratios.
Output strokes of any length can be arrived at, for any of these
designs.
I need to build a new (left side) deck / extension for the test bench,
in order to install a second sliding unit at 90 degrees to the first sliding
unit. This is something I have put off for as long as I can.
I have some thing improvised at present, but it is inadequate.
I will update with that progress.
Also a short video of the magnetic force shield 2 design.
Later today ?

The operation of the inventive engine 10 will now be described. It is first to be noted that the pull of an electromagnet varies as a function of the area of the holding surface muliplied by the square of the flux density divided by a constant. Also, that the flux density increases as the distance to the holding surface decreases. Hence, changes in the flux density is the greatest contributor to the pulling force of an electromagnet. Experiments conducted by the inventor have shown that an electromagnet powered by two "D" cell batteries can produce a holding force of 500 pounds and that the magnetic attraction force varies with the distance between the surface of the electromagnet and the item to be lifted.
It was found, that at a distance of one-eighth of an inch, the force is approximately 7.8 pounds; at a distance of approximately one-twelfth of an inch the force is 31 pounds; at a distance of approximately one/twenty-fourth of an inch the force is 125 pounds; and, as stated, at contact, the force is 500 pounds. Thus, a usable force begins when the distance is one-eighth of an inch and increases rapidly thereafter.

the Lumen magnetic forced track (from green shield view above and below comparation : 100% symmetry )
symmetry yes / force is balanced between the output magnets, WHEN THE SHIELD ARRAY IS
IN PLACE (BETWEEN).
note... Green colored structures / materials are not magnetic.

the "fine tuning single magnets" : steel plate ?
Symmetry / force balancing, in order to remove and / or install the shield array
is difficult to arrive at.
A magnet attracting to the shield array at a given near distance, is more effective than
a magnet repelling to the shield array at that same given near distance
(in the direction the shield insertion and / or removal )
(into the page and out from the page).
therefore
More magnets are required on the repelling to the shield array, sides of the shield, in order
to arrive at a balance / neutralization of forces IN REGARD TO INSERTION AND / OR REMOVAL
OF THE SHIELD ARRAY.
The "fine tuning" magnets are as an aid in arriving at a more precise balance in THAT regard.

increases force at the cost of distance of field extension, trades force for distance.
No gain in kinetic energy.

I do not know why ,but I feel to see this device like a "mechanical flip-flop" !
Related the attraction/repulsion force difference : http://jnaudin.free.fr/html/2magpup.htm (http://jnaudin.free.fr/html/2magpup.htm)
but the tangential repulsive force measured is 574 g.
the axial repulsive force measured is 1254 g
Did You attractive force and repulsive force difference measurements ?
1. As you know, force multiplied by displacement = kinetic energy.
Not force alone.
2. Behaviors / that which is possible in attracting modes
and
behaviors / that which is possible in repelling modes are very different.
3. There are perhaps a dozen minor variations possible and worth exploring
in EACH of these designs. Multiply that times 6 designs and you have
60 variations (at least).
Too many to discuss and also build / measure and /or maintain
continuity to the topic.
4. Post / discuss these other, although relevant and related designs (PEMANANT MAGNET ONLY)
in the
https://overunity.com/18501/the-magnet-fantasic/
topic, and we will build the best archive / body of discussions of "the magnet fantastic"
on the entire internet ? Or make a chaotic discontinuous mess ?
THE CHOICE IS OURS.

As LankaIV has recently reminded / pointed out, WHEN EVER these magnet interactions
DO NOT add up as Input = output, we have something worth looking into.
It is possible that work done by the shield element and which is caused by magnetic
forces, will be of a greater magnitude of work than the combination of the other interactions.
What is not desirable, is that they be of the same magnitude of work / energy.
Only measurements and time can tell.

Hello
an interesting video.
Wixen in action. DMI Effect. - YouTube (https://www.youtube.com/watch?v=5uCBta5t_Rg&t=38s)
floor
Another of his demos.
https://www.youtube.com/watch?v=xOBZsCWMDzI
Please see the previous two posts...
In regard to the just previous post / video...
You can see the same kind of physical effect / results, but while useing a
different magnet interaction set here @
https://www.dailymotion.com/video/x7b3x9a
In the "T.D." demonstration (daily motion),
both
the input work
and
the output work
are cyclically done and then undone.
i.e. There is no net work, input.
There is no net work, output.
Curious is it not ?
I'm pretty sure, that by linking a long series of these units
in an escalating in scale manner, as non work out connected to the next non work in
One could lift an elephant over and over ?
As long as you put it back down over and over ?
And this
by lifting 105 g by that 22 deg. worth of travel ? (in the video)
Not sure though. I mean, I havn't tried it.
5,000 pounds or 2,267,962 grams = average elephant + - ...
Each magnet unit used in series increases the height lifted by an additional 45 % ...
100 / 40 degrees = 2.5
2.5 x 22 degrees = 55 %
100 % - 55 % = 45 %
Each magnet unit used in series increases the weight lifted by an additional 8.696 % ...
115g / 100 = 0.86956521739130434782608695652174
105 g x 0.869 = 91.304 %
100 % - 91.304 % = 8.696 %
There are 0.27930 mm of lift per each degree that is read from either of the degree scales.
The first unit lifts 115 grams by 40 degrees or 11.172 mm ( 0.27930 x 40 deg. = 11.172 mm)
115g x 11.172 mm
The first unit input is 105 grams, but the actual force required (average force) over
the 22 degrees (6.1446 mm of fall) is around 85 grams. ( 0.27930 x 22 deg. = 6.1446 mm)
85g x 6.1446 mm
How many magnet units in series in order to lift the elephant and what would be the height of
that lifting ?
How about this then...
Instead of an elephant, a magnet and weight object, lowered through a coil that
is connected to a load while the weight is being lowered ?
It doesn't have to be as heavy as an elephant though...
https://www.dailymotion.com/video/x7b3x9a
The weight and magnet should be able to fall through a coil, even when the coil is
loaded and while undoing the work as lifting done by the rotating magnet ? !
