The past three days I've been busy with finding out how a specific formula works. Right now, I am really down to my luck. The formula in question is the one in the attachments.
The reason that I wanted to use this specific formula is because it lets me calculate the coupling coefficient using theoretical input (such as the distance). The problem I am constantly facing is that the output value isn't between 0 and 1 (as it should be).
Right now I am using the following values for mu formula:
Clearly I am doing something wrong, but right now I already spent a lot of time on it that I cannot spot the error anymore. I am not asking for a complete solution for my problem, a push towards the right direction would already be such a great help. More information on this formula can be found at:

 A2=2778.5mm2
 L02=3μH
 L01=3μH
 r=10mm
 x=20mm
 μ0=0.999994 (copper: http://www.engineeringtoolbox.com/permeabilityd_1923.html)
