lot of good answers, some close to what i am trying to ask, others while
informative are not quite what i am looking for.

yes i understand that we have all sorts of stuff going on
IR losses, iron losses, hysterisis, eddy currents, at least 5 different forms of reactances, armature reaction, leakage inductance, slot leakage, and all sorts of other things.

some designs are dominated by part of the above list, some others dominated by others.

after reading some of the responses

how about this example

a single pole standing on the page vertically, lets make it a nail in a board

onto this nail we wind a coil clockwise and bring its leads out to the left of the page

then we wind another coil counterclockwise (equal turns) and bring its leads out the right side of the page.

there will be no interconnection of the coils

we now pass a magnet rotor over the nail head,

we get induction into both coils, as the magnets pass we get a positive pulse in one coil and a negative in the other when the north magnet pole goes over and the opposing effect when the south magnet goes over.

so far so good.

now we apply loading to both coils, seperate but equal loading.

the current flowing through the coils will affect the flux at the airgap
armature reaction, and will increase with current in the coil, but

with opposing coils the back induction that rises with current is offset by the opposing coils so therefore there is no armature reaction (in theory)

the question that remains is

would the back induction of one coil try to fight and reduce the output of the other coil and visa versa?

(i gotta learn how to make a sketch and post it)

the reason i ask is based on the fact that some alternators (large ones) use a second winding afixed to the top of the pole pieces that is shorted or shunted like a shaded pole in order to reduce the armature reaction, and
i am working on trying to figure a way of reducing pole reactance, and reducing pole inductance if possible is a step in this direction.

anyway sorry if i try your patience guys
i have only spent about the last year (intensively) studying alternator design
devoteing about 2 hours per day on average to reading everything i can find on the subject.
perhaps in a couple years i will know a bit more, but i suspect i will only have more complex questions.
