Coil Calculator - Single-layer and mutil-layer coil calculation in javascript

Legend:
outer diameter: diameter of the winding form including the wire layer(s)
inner diameter: diameter of the winding form
length: length of the coil (only the coil itself, not the winding form)
Don't forget to select your unit for outer diameter, inner diameter and length!
All calculations apply to solenoidal (cylinder) coils only!

Select your unit: mm inch

Inductance calculation:

Multi-layer Coil:

L = N*N * 0.2*a*a / ( 3*a + 9*l + 10*(a-b))

N =	This is not phishing, this is art! Read more here what this is about. turns
outer diameter: a =	This is not phishing, this is art! Read more here what this is about.
inner diameter: b =	This is not phishing, this is art! Read more here what this is about.
length: l =	This is not phishing, this is art! Read more here what this is about.

L =	This is not phishing, this is art! Read more here what this is about. μH

Single-layer Coil:

L = N*N * a*a/4 / (9*a/2 + 10*l)

N =	This is not phishing, this is art! Read more here what this is about. turns
outer diameter: a =	This is not phishing, this is art! Read more here what this is about.
length: l =	This is not phishing, this is art! Read more here what this is about.

L =	This is not phishing, this is art! Read more here what this is about. μH

"Number of turns" calculation:

Multi-layer Coil:

N = sqrt( L * ( 3*a + 9*l + 10*(a-b)) / (0.2*a*a) )

L =	This is not phishing, this is art! Read more here what this is about. μH
outer diameter: a =	This is not phishing, this is art! Read more here what this is about.
inner diameter: b =	This is not phishing, this is art! Read more here what this is about.
length: l =	This is not phishing, this is art! Read more here what this is about.

N =	This is not phishing, this is art! Read more here what this is about. turns

Single-layer Coil:

N = sqrt( L * (9*a/2 + 10*l) / (a*a/4) )

L =	This is not phishing, this is art! Read more here what this is about. μH
outer diameter: a =	This is not phishing, this is art! Read more here what this is about.
length: l =	This is not phishing, this is art! Read more here what this is about.

N =	This is not phishing, this is art! Read more here what this is about. turns
