Ok, but I recall from my old electric motor class (tech high schoool,
pre- 1960) that motor 'strength' had a lot to do with AMP-TURNS, so if I
have 2 windings, both of the same turns count, and both carrying
current, dont I get twice the magnetic field? Obviously if your
'stranded wire' analogy above is correct then I dont, but since these
wires are insulted from ecah other then we have 'different amps' flowing
through each coil.
