Magnetic Flux Density of a single turn rectangular loop

[Catalyst]

magnetic flux rectangular loop

Hi folks,

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

a single turn rectangular loop

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
