- Homework Statement
- For a final laboratory project, I am trying to find an experimental value for the permeability of free space by determining the Inductance of a solenoid.
I have found a good value of inductance for my solenoid, but the problem is that it is that my solenoid has multiple layers of coil.
- Relevant Equations
- L = (μ₀ * μᵣ * N² * A) / l
I realize that the standard formula for the inductance of a solenoid (L = (μ₀ * N² * A) / l, where A is the cross sectional area, N is the number of turns and l is the length) is for solenoids with only one layer of wire. I thought I could find μ₀ using this simple formula, but it does not work.
Is there a standard formula for coils with more layers? I looked around online but I could not find anything, and me TA did not know either. How can I go about calculating the permeability constant given my experimental inductance?
