Lecture Notes - Mutual Inductance and Linear Transformers File
... When two coils are placed close to each other, a changing flux in one coil will cause an induced voltage in the second coil. The coils are said to have mutual inductance M, which can either add or subtract from the total inductance depending on if the fields are aiding or opposing. Mutual induct ...
