Re: for Inductance Calculation

Hi Matt and everyone,

    The formula L=Nr*2/9r+10h........for a single layer air coil.

Matt, the 9 and 10 in the denominator equation, are those a constant of
some sort??? and of what sort???

This is the formula I have;  L=N(squared) x permeability x A / l

L is inductance in henries

N is # of turns

Permeability is a constant of 1  (for air cores)

A = area of core

l = length of coil

Anyway,

Wade
