hi all.
how can calculate inductance of coil when we have dielectric core (not air core). we have circular core.
thanks and regards
 

Dear zohre
Hi
What kind of core ? do you know any thing about it's permeability ? is it lower that air or higher ?

thanks
excuse me, but i dont want Toroid. i have a cylinderical teflon core. whats the formula for calculate inductance?
 

can you describe the specifications of your inductance ?
It is simple . it depends on number of turns . u ( permeability ) . diagonal . and the length of winding .

The dielectric core does NOT change inductance. Only a magnetic core (µr<>1) will change inductance.

Sounds like you didn't check the links. They provide calculation of cylindrical "air core" inductors as well.
 

i recommend the paperback ;)
