So, I was wondering, what is the electrical model of mutual inductance?
It's explained in my physics textbook, with no electrical significance as far as I can tell.
Leakage inductance is far simpler to deal with, but I noticed that my textbook doesn't mention it and internet sites deal with cored examples. Air core transformers have leakage inductance too!!
Purpose: wondering what the LL of coupled, concentric solenoids with different diameters is.
Presumably, k (coupling konstant) is roughly the ratio of areas, but I can't find where to get LL from that.
