## Homework Statement

I am trying to find the mtuual inductance between two p-core inductors (they share the same core) but I am not sure how the coupling coefficient would be calculated. I know the inductance of both coils. What else would I have to know in order to calculate the coupling coefficient if I am not given the mutual inductance?

## Homework Equations

M = k*sqrt(L1*L2)

where M is mutual inductance, k is coupling coefficient, L1 and L2 are inductances of first and second coils respectively.

## The Attempt at a Solution

Dunno.
