Coupling coefficient and mutual inductance

AI Thread Summary
The coupling coefficient, denoted as k, quantifies the fraction of magnetic flux from one inductor that links with another inductor. It is directly related to the mutual inductance, indicating how effectively the inductors interact magnetically. The value of k ranges from 0 to 1, where 1 signifies perfect coupling and 0 indicates no coupling. A higher coupling coefficient implies a greater fraction of flux from one inductor passing through the other. Understanding this relationship is crucial for optimizing inductive components in electrical circuits.

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.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
