@LancaTV

Thank you for your interest and the link.

I intend to return to this topic on a more full basis....soon.  Our main endeavor on the 1.5 : 1 ratio (work from magnets)  topic is nearing completion.


                                               Cheers

I think that this last "odd shaped toroid shell" with an external non toroidal field coil, (the coil is cylindrical), will fly.

I hope the previously posted designs / studies have not been too much of a waste of anyone's time. May be they were
as thought provoking for others as they were for me.

One can see from the study (split coil JPGs) that the mag. fields from the electro. mag. will penetrate the perm. mag. at it's core
as well as at it's external field. 

The external part of the perm. mag. field could combine with the electro. mag's. internal field. but the perm. mag's internal field
would  be opposing the electro. mag's  field. This cancellation would reduce or eliminate any net gain, otherwise resulting from the combining of the electro. and perm. mag. fields.

Not so in this last design.

Please find attached "shell with hole JPG"

Cheers


     Except for my initial posts, my drawings above. are just my notes as I look at both the designs ideas and their physics.  They may be good ideas or bad ideas.  I often draw them, to give me clarity.  I post them here just to show the trek of my thinking.

Some relevant designs, maybe for the interior of the electro permanent magnet.

                           See the PDF file below

                A little clearer description of the drawings

                                   ps

                                    maybe this can form the "mag core" of an electro permanent magnet "shell" ?

Some days, I'm really itching to get back to this topic, and do some builds / experimentation / tests.  But I'm too busy else where.
