Malcolm, Bert, All,

When the pri and sec are physically close to each other, the relative
polarities of the pri and sec should be aligned, in order to minimize
the voltage difference between them.
Given all of the possible 'minus-sign' errors, and the fact that the
two coils are 90 deg out of phase, should the coils have the same or
opposite 'handedness' when wound?
I am no longer completely sure of the correct answer, and would much
appreciate a confirmation.  If possible, a concise explanation of how
the answer was obtained would be far preferable to anecdotal evidence.


Thanks in advance --GL
