Mutual Inductance Formula
The following equation is used to calculate the mutual inductance between 2 inductors.
I = k * Sqrt ( L1 * L2 )
- I is the mutual inductance
- k is the coupling coefficient
- L1 is one inductance
- L2 is another inductance
Mutual Inductance Definition
Mutual inductance is the total inductance between two coupled inductors.
