O.U. Magnet force shielding 1

[Floor]

@ Norman

In this design ...

While the shield is out, and the output magnet is repelled ....
With an average force of 400 grams, over a travel distance of 2 inches
this is 800 inch grams of work or work units (not converted to joules).
This is output.

Two inputs, each at < 5 grams average force over two inches of travel (shield in and out)
is equal to 10 inch grams or work units....    times 2, or 20 inch grams of work input.

Ratio is 20 in to 800 out.

This isn't even counting the additional work output, which is present as the output
magnet's travel in attraction while the shield magnet is in between...

20:800 or 2:80 or 1:40 
probably 1:60 if the other output (attraction) were included.

    So...
          a 1 to 30 ratio is a conservative estimation... probably ...

Thanks Floor, that number is fantastic not you need to extract that work by letting the magnets move apart...
But did you account for further weaker?
The work out is not linear.

re post / slight mod. of first post in this topic


This design goes back to 2017.
Some folks are well aware of it, since that time.
Others missed out on it.


Closer stronger, farther weaker...
out put 1 (repulsion)

740 g at 1/2 inch
700 g at 9/16
650 g at 5/8
600 g at 5/8
550 g at 11/16
500 g at 3/4
450 g at 13/16
400 g at 7/8
350 g at 31/32
300 g at 1 1/16
250 g at 1 3/16
200 g at 1 5/16
150 g at 1 5/8
100 g at 1 3/4
50 g at 2 9/16

input 1 shield moved out < 5 grams by 2 inches
input 2 shield moved in < 5 grams by 2 inches

out put 2 (attraction)
Return of out put magnets to starting position is also an out put and gives
a net gain in energy as mechanical work.

Thanks Floor for the great numbers.
My spread sheet shows OU about 40 which is fantastic...

Now get those magnets harnessed up and you have OU that can be seriously cascaded.
Ie the output can drive multiple equal setups.
And get some replications like the Naudin lifter project.
My goal would be to have a table top sized toy that all can see.....
move 1 by hand and several others move the same amount..
CONGRATS

Thanks Norman.

I'm working on / neatly finished with the set up / and new demonstration video.

No shaky camera ! Good audio.

The test bed now has two sets of linear slide rails.
The shield or shunting magnet setup as well as the output magnet setup, each
have their / its own linear bearings and rails.
These are at 90 deg to each other.
No disassembling then reinstalling the magnets for the demonstration is needed.

   best wishes
