Here you can see the formulas that the calculator uses.

Coil on a ferrite rod:

On-line ferrite ring core inductor calculator
ferrite toroid calculator
ENTER THE INPUT DATA:
Select units:   AWG →   SWG → 


L – Required inductance

Ferrite rod parameters:
l =    – Length of the rod
d =    – Diameter of the rod
µ =  – Initial magnetic permeability

Coil parameters:
dc =    – Diameter of the coil-former
x =    – Shift from the rod center
dw =    – Wire diameter    
Winding pitch / wire diameter relation: p/dw =  (1 .. 2)

Calculate
RESULT:
N =  – Number of turns
AL =  – Inductance factor of the rod [nH/N2]
a =    – Length of the winding
