O.U. Magnet force shielding 2 and so on

<< < (2/4) > >>

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 ?
  best wishes

Reply #3 A,B outer magnets wipping-possibility           magnetic force effect under 90°,60°,30° vertical/horizontal position ( spring ?)

the Lumen magnetic forced track (from green shield view above and below comparation : 100% symmetry )

the "asymmetry" = outer input ! transformation efficiency to output ? <100% (!?)

the "fine tuning single magnets" : steel plate ?

the "fine tuning magnets (one or both) : coil(circuit) wrapped ?

instead D-battery capacitor ?

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.

symmetry yes / force is balanced between the output magnets, WHEN THE SHIELD ARRAY IS

note... Green colored structures / materials are not magnetic.

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).

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

The "fine tuning" magnets are as an aid in arriving at a more precise balance in THAT regard.

That design

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

I'm not ready to move into / discuss the Flynn / other  methods at this time / in this topic.
