Thanks.
Lets me know I can't take a shortcut on another project.

You're welcome; my pleasure. :-)

NO. Not the same effect. If you soldered the ends of the multistrands you
would have 200 turns only. You would have 10 parallel coils sharing current,
unevenly, due to connection differences and differing reluctance between
strands.

For 2000 turns,  you put the form in a hand drill, measure the gearing step
up ratio and count hand crank turns mentally. 2000 / 10 = 200 turns only.


No.
The field strength is related to the number of coils.
So if I start out and go around the coil form 2,000
times with one wire, could I get the same effect by
using a multistrand, with each strand insulated
from the adjacent one? If I were to use a 10 strand
and only go around the coil form 200 times, would
it have the same effect?
Litz wire would not have much current capacity, but
would it have the same instantaneous magnetic field
from a capacitive discharge?
It's not a question of multiple solder joints along the way,
it would be a beginning, and an end, with wires soldered
together at those points only.

The snow hid it well.
he slipped and fell, the knife killed,
but there was no loss.
