Work from 2 magnets > 19% output 2

[lumen]

I have to say this new laundry room is taking longer than I wanted.
12' x 18' , drywall, plumbing, flooring, ceiling, electrical.... what else?

I need to get back and collect more data before I'm dead!
Hope to be back soon.

QUOTE FROM Low-Q
"OK. Iron will narrow the magnetic flux into its core on the expense of less magnetic flux outside it, but the total magnetism, if you could "count" the magnetic lines, will be the same number as in an electromagnet with an air core.
The flux must loop from north to south. When you use an iron core, the fluxlines are taking sharper corners than using air core. Therfor the magnetic force is greater with an iron core, but on the expense on how far that force can reach - normally in a very narrow space.
It is where the fluxlines takes its sharpest corners where the force is greatest - closest to the physical corners/circumference of the iron core at the south or north pole.

What has this to do with the twist drive? Does it make any difference in practice wether you use iron core or not? No criticism, just asking."

Firstly...  I am not an expert in magnets. I once thought, that an Iron core only concentrated a coils magnetic field, but did not
actually increase it. 

I keep learning more all the time.

Quote from  http://hyperphysics.phy-astr.gsu.edu/Hbase/magnetic/elemag.html

"Electromagnets are usually in the form of iron core solenoids. The ferromagnetic property of the iron core causes the internal magnetic domains of the iron to line up with THE SMALLER DRIVING MAGNETIC FIELD produced by the current in the solenoid. The effect is the multiplication of the magnetic field by factors of tens to even thousands." END QUOTE

@Lumen

Don't rush it.
Just get into it, and geter done.

@ all readers.

Here is a configuration, in which RO is the output and
SL is the input. 

The work in to work out ratio can become
extreamly large. 

This is because the work to place the RO (rotating) magnet
between the two SL (slideing) magnets ocuurs mainly, just as
the ends of magnets SL begin to pass the end of
magnet RO.

The  length (latteral) of the magnets can be increased, by
useing multiple magnets, placed end to end.

Increasing the length of the magnets DOES NOT increase
the input work, but it DOES Increase the output work.

I once thought, that an Iron core only concentrated a coils magnetic field, but did not

And you were right. It does not increase, but concentrate the field to a narrow space. Increasing flux density into a narrower space like using a lens to focus sunlight so you can burn ants.
The energy in the light does not increase, but is narrowed to a smaller point so the energy density increase.
The total sunlight energy, or magnetic flux, appears to increase, but it doesn't. Only the density changes on the expence of a smaller space.
Remember that the only magnetic field lines that is available, is only those that is around the wire in the coil.
