"In the Ferrofluid and Mag-Gas plasma  EPG devices the maintenance of magnetic domain is critical for optimum power generation.

In the slurry systems by Meyer, Hauswirth, and Miller et al, (ferrofluid) the disruption of magnetic field orientation is mitigated by the use of orientation coils.

In the  gas plasma devices there are several  alignment  forces present. First, the use of the linear magnetic drives for pumps and then secondly, the magnetic coupling in the paramagnetic matrix

The domains are in one case about 10Nm and the gaseous systems much smaller atomic clusters

The method for creation of  larger magnetic domains is as follows:

1 Select the paramagnetic material  Fe, Co, or Ni   (either powder or larger filings)

2 Select the matrix be used.  A thermosetting  plastic such as the type used in hot glues
(This is similar to the systems  using PIB or poly-silanes )ed.

3. Melt the plastic to the highest temperature possible without breakdown
  (The  goal is to minimize viscosity) ed.

4 Introduce the paramagnetic material.  Brownian movement will be lowered
   by the viscous nature of the plastic,  When large amounts of magnetite are
   used on a vol/vol basis the ferrofluids increase rapidly in viscosity due to thixotropic
   and other rheological factors. (Bremen Conference Notes in Dropbox)

5. The reservoir of the paramagnetic//plastic suspension is heated and constantly stirred at this point

6  The molten  slurry is extruded  under pressure through a heated magnetic alignment tube
 
7  A nozzle with many small orifices is surrounded by a strong magnetic collar or coil to align the
    small particles before cooling the magnetic filament in air or  water bath.  Spinnerets similar to
    "cotton candy" machines are suitable for air dry systems

8  After drying the collected filament, it is then ready to be processed into smaller segments  by
    mechanical means.

9 The orientation of the magnetized  particles is axial to the magnetic force applied and is locked
    from further axial change within the  smaller segments due to the phase change of the suspending
    agent  (the thermosetting plastic or glue
 
10. The increased vol/vol ratio  of ferromagnetic material to matrix would result in aa larger magnetic susceptibly and
      would result in  greater COP values in the mechanical EPG series (over 3 as reported) but the EFFECTIVE
       SURFACE AREA OF CONTACT OF MAGNETIZED PARTICLES IS DRASTICALLY REDUCED DUE
       TO THE LARGER SIZE OF THE MAGNETIC REGIONS. and due to fewer particles per cubic
       centimeter, the viscosity is REDUCED"
       
        Which is easier to stir, a pound of corn flour,  a pound of corn meal or a pound of corn kernels when placed in
        and mixed with a pint of water? ed

        The corn flour "sets up" like  paste or a very thick tortilla batter
        The corn meal forms a thin gruel
        The corn kernels are easily swished around. ed.

11. "The fixation of the magnetic particles maintain and creates a magnetic matrix ,but the use of overall
larger domains or groups in the plastic "bar magnets"  results in lower viscosity permanently magnetized
media. The oil or water base used in the slurry becomes the dominant factor in viscosity with the same
or greater magnetic susceptibility per cc

  11  the  large magnetic particles or magnetic clusters can also subsequently be exposed or coated with either hydrophobic or hydrophilic  treatments depending on choice of carrier liquid"

editor note:   thanks  Nice work!!  This is similar concept to the PIB and Poly silane  series discussed  elsewhere on this page.  ed. jm

Well from a mathematical standpoint, the Keppler Conjecture would indicate a  packing  ratio of about 07 or so
for the nanospheres with the voids filled with resin, liquid or air.   So the density would be a weighted average
of the relative volumes  and densities of each of the nanospheres and carrier liquid

Perhaps a ferrofluid as the carrier liquid with the plastic micro magnetic bar magnets suspended within would increase the
magnetic susceptibly of the total epg core with an acceptable  change in viscosity
