- Hello, I was wondering how to tranpose this equation? I am sure that i'm doing it correctly but I am getting a wrong answer. Any help will be much appreciated
So the equation is
L=μoμrN^2A/l
I am wanting to make μr the subject and I think this is how i do it?
μr = L*l/μoN^2A
However when I type in this equation i am expecting to get about 200 for the relative permeability of iron. However, i am getting like 9x10-3 which is nowhere near 200.
For example here are my figures
μo = 4 * pi * 10-7
N^2 = 105^2
A = 0.00196
L= 57 mHenrys
l= 0.095
I assume to get 200 for relative permeability as when i use the first equation using 200 I get that L is 57 mH but when i try tranpose and find μr I don't get 200.
If anyone could help i'd really appreciate it thank you :)
