I'm still confused about the fieled for the primary.

Someone said that only the first few inches of the secondary are coupled to
the primary.  This seams to me not to be true as the field is 40" high and
my secondary is 36" high, so it does not seam right.  By that, I could build
a coil twice as high and just have half the coil coupled.

Can anyone tell me how "big" the fieled is and the coupling strength from
primary to secondary ?



All the beST,
Chris.
