"WebMutual Inductance. Mutual Inductance is the interaction of one coils magnetic field on another coil as it induces a voltage in the adjacent coil. Mutual inductance is a circuit parameter between two magnetically coupled coils and defines the ratio of a time-varying magnetic flux created by one coil being induced into a neighbouring second coil.
