Slide6Equivalence
In a conservative field, Lkm = LmkIn general:
Slide7Aiding and Opposing Flux
When both currents enter the polarity marks or when both currents exit from the polarity marks, the mutual inductance,
L
km
is considered as positive.
Otherwise,
L
km
is negative.
Slide8Aiding and Opposing Flux
Here, L12 = L21 would be considered negative.
