DIY Flapjack Coil Jig

[z.monkey]

Y'all keep using the term pancake, do you not like flapjack?

I'm in Texas, so I might as well call it a tortilla coil...

It is yellow, like a maiz tortilla...

The proper term is planar coil...

FlapJack it is then... 

The lines shown on the equatorial plane should be from charged/moving particle angular movement. At least that is the way it works on my bench

Look at a similar 'sim' on a single layer coil. Any more than one layer and it is no longer interesting. On a single layer coil from the top center it may appear as North. From the bottom center the same wire section will appear as South.

I agree that pancake coils can do interesting things.

Howdy Broli,

Your simulation shows that the magnetic major axis is formed in the center of the loops of wire, perpendicular to the windings.  No matter whether it is one winding or many the major axis forms in the center of the loops and perpendicular to the windings.  This establishes that the planar coil will make a magnetic field which is analogous to a solenoid, except that it is exaggerated in the X/Y Plane and not on the Z axis like a solenoid.

In the simulation the two planar coils are pressed together tightly and there is no Z axis clearance in the center of the planar coils.  Lets deal with one magnetic field first.  Keep in mind that the accretion happens in the centers of the magnetic loops.  This center is where the slowest movement of flux occurs.  This allows the extremely high frequency magnetic flux currents come down to a frequency where we can perceive and manipulate them.  This down conversion of energy is what makes the magnetic flux turn in to electron energies that we can use.  So the planar coil only needs to cover the center region of the equatorial orbital plane.  It should (preliminary guess) only require around 50% of the area of the plane and be oriented in the center of the plane between the magnetic major axis and the extreme edge of the magnetic filed.  This would allow for a relatively large core on the magnetic major axis (Z axis) to maximize the magnetic field.  The magnetic major axis (Z axis) core defines the extent of the magnetic field.

So do you want to simulate the Flapjack Coil as I built it?  The magnetic major axis core is 0.850 inches in diameter, which the outer 0.120 inches in the 18 gauge wire, and the remainder is soft iron tubing and a #2 Steel 1/2 inch machine screw.  The planar coil substrate is a the remainder of a CD-ROM.  I stripped the media off of it so it is just a piece of plastic, no magnetic value.  Both coils are secured with epoxy, again no magnetic value.  There is a strange core property which is bothersome to me.  I have the core bolted to a piece of poplar to secure it.  I also have a poplar spacer at the top of the core to provide a equal distance between the ends of the core and the planar coil.  This means that I have a bolt in the middle, then there is a fender washer on each side, then the poplar, then another fender washer, then a split lock washer, then a 1/2 inch nut on each side.  I would like to make this core as short and squat as possible, but haven't found a good way to mount it yet.  It is critical that the planar coil is exactly in the center on the Z axis (magnetic major axis), and plumb, and square...

I don't have a magnetic simulator.  I do have a lot of spice tools, EDA stuff.  I have never trusted computer simulations.  I have always be the kind of guy to build it, run it, then check the math.

There is another thread where they are experimenting with a solenoid type coil but using NdFeB magnets as the core.  I am going to make another version of this coil which has the  NdFeB magnets as the core.  Here is a link...

The accretion happens when the magnetic flux loops fluctuate.  This means you only have to make them wiggle a little to get the magic to happen.  So the idea is to take a really strong magnetic field, and then modulate it.  We already have a super dense magnetic flux environment with the NdFeB magnets.  We use the electronics to make this already dense field wiggle and we should be able to collect an significant amount of electron energies...

The original idea of modifying the transformer to maximize accretion is still at work here, but the addition of the NdFeB magnets can help to maximize this effect.  Fortunately, standard off the shelf magnets can be used to achieve this effect, here is a link...
