Just in case, please note this point   Helmholtz coil - Wikipedia

The coils can be more than two, switched on in parallel or in series, or as UFOpolics one by one in series, the principle of magnetic field will be the same.

Sorry for the post, I think - that this point should not be missed.

Hello Rakarskiy!!

Many thanks for that contribution!!

Many great math analysis there, as also when varying distance "h" to a larger value (given the normal as radius (r) equal to h) it "worsens" the Field uniformity...

However, when we add a center longitudinal steel core, like we are doing here (and which is not part of a Helmholtz Pair) the Field takes a different configuration than with a hollow (air) core, besides it strengthens much more.

Thanks

Hello to All,

I have removed all data related input on "Asymmetric Pulses"...since I was only pulsing All Coils at certain timing...But Input Amperage was high. (thanks Greg for finding it)

So, it is a "No Go" deal, even whenever I accelerated amps went down, some, and Output up, a bit, but still not enough...and this is not what we are looking for.

If we find a better Sequence, even differing from Figuera, fine, we will go for it, if it gets great results...if not, we will discard it...and go back to Figuera.

We can pulse 2 Coils in parallel, in a Sequence between 4 or more coils, always following a Sequence.

And it is simple in Magnetism Terms, We need to either Expand and Shrink, or Displace from point A to point B the Magnetic Fields, at LOW COST on Input and greater results on Output.

Thanks

Hello Ufopolitics, An extension on the design of the unit R. If you look closely at the connections from the commutator from connections #1 and #8 you will see that as #1 wire connects to the far left at the lower edge of the BOX' and the #8 wire connects to the FAR side of the box. I interpret that to mean that ALL contacts on the lower part that have wires connected are north coils wound CCW and the wires of the FAR side are south coils and are wound CW.

SINCE they are pairs and are fed current from OPPOSITE ends, they are wound TOGETHER  as a CCW spiral on the steel core and then charged from OPPOSITE ends making the reverse current flow CW. ANOTHER one of those situations that Figuera did not draw the details for is the S pole connections of the commutator. If we count over 3 Vs of the squiggly zigzag coils in unit R, and fold the paper in half, so that both sets of 3Vs are of top of each other and crease the paper. Now unfold it and the right side if the crease is S pole coils and the left of the crease are the N pole coils. Now AT the crease there is one squiggly line that is cut in half by the fold. This is the RELUCTANCE flux that remains AFTER the last current from the commutator flows at contacts #8 and#16. HOW to get this reluctance flux over to the START of the opposite pole without SPARKING in the commutator is STILL a question to be researched. I hope this adds some clarity there. Thanks GreyWolf47

A little more on that thought.

This book was designed to explain the complex principles of the new technology of electricity in a way that could be understood by the average person. The book contains many detailed illustrations, and most of the illustrative content became the basis for decades of subsequent books published under the Audels brand. The illustrative content of those books can still be found in new Audels books sold today.

I was personally interested in another illustration of a cross-section of electric machines from Figuer's time:

I can just see a cross-section of the magnetic system of a 1902 Figuera generator.
In that 1902 patent, all the details of the phase inductor (in red) were hidden, the method of excitation of the electrical circuit was not described.
