Does anyone have a formula for calculating inductance for a choke using number of turns and cross section. I will be using an old torroid core as a form for the choke. Thanks.
If it's not nailed down, it's mine.
If I can pry it loose, it's not nailed down.
L=(n^2) x Mu x S / l
l, Length of magnetic material (m)
S, cross section of magnetic material m^2
Mu, permeaibility of magnetic material
n, number of turns
If you have a inductance and if you know the value of inductance and turn numbers. (these L1 and n1)
If you want the L2 inductance,
n2=n1* sqr(L2/L1)
The length of magnetic material for a torriod core, would that be a mid core circumfrence figure.
