- Homework Statement
- Calculate the flux linkage inside a coaxial cable

- Relevant Equations
- total flux linkage λ=dΨ*Ienclosed/I or λ=N*Ψ

In Sadiku, he used the formula dλ=dΨ * Ienclosed/I

to determine the total flux linkage for coaxial cable for ρ<a and for a<ρ<b, but I applied this formula for the solenoid and it didn't work, the way that works for the solenoid is by using λ=N*Ψ.

So why we multiply by Ienclosed/I in the coaxial cable?
