How about a comparison between a 24 inch long, 2 inch diameter straight coil
and it's 2 inch diameter 24 inch inner circumference toroidal counterpart...

I know that a given coil of any shape will be affected by iron/ferrite/air
core, but I have no sense for how turning a straight coil around into a
toroid will affect it.

Maybe if someone could post the equation for each, that would help me out...

Thanks.
