Coupling coefficient and mutual inductance

Click For Summary
SUMMARY

The coupling coefficient (k) directly relates to the fraction of magnetic flux from one inductor that links with another inductor. Specifically, k represents the ratio of the magnetic flux that passes through the second inductor due to the first inductor's magnetic field. This relationship is crucial for understanding mutual inductance in coupled inductors, where a higher coupling coefficient indicates more efficient magnetic coupling between the inductors.

What is the relation between the coupling coefficient and the fraction of flux from one inductor going through the other inductor?

Can you tell us what you know so far about these topics? What do you think the answer is?
 
I guess k = fraction of flux generated by one inductor going through the other, with the appropriate sign.
