magnetic flux rectangular loop
Does anyone have any links or resources where I can view the formula for calculating the inductance of a single turn rectangular conductor loop and the method for deriving it?
Any advice is appreciated :)

L = 0.394*(r^2)*(N^2) / ( 9*r + 10*length )
where:
L = inductance in uH
r = coil radius in centimetres
N = number of turns
length = length of the coil in centimetres
May i ask where that equation is from?
Hi:
You can get the equation of the dc self inductance from Radio Frequency Integrated Circuit Design, by John Rogers and Calvin Plett. Hope this helps

Thanks for the responses :)
From what I can see, all of those equations are for circular loops, not for rectangular structures.
If I have a conducting loop that is 40cm by 20cm, built with copper tubing (15mm diameter) where do I start when I want to derive a formula for the magnetic flux density B or magnetic field strength H.
These will heavily affect the result of the inductance for the structure surely.
I'm lost :(

from the L you can derive the flux density
