Take a helical wound 150mm diameter primary with 15 turns positioned around
a helical wound 75mm secondary with 1500 turns.
This will have a different square root of ratio of inductances from a
helical wound 300mm diameter primary with 15 turns wound positioned around
the same 75mm secondary with 1500 turns.
These two conditions meet your geometry and turns requirement, but because
the inductances of the two primaries are different the [square root of ratio
of secondary/primary] gains ratio will be different. What is missing from
