mutual inductance in circuit analysis

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 neighboring second coil.
Previously we saw that an inductor generates a self-induced emf as a result of a changing magnetic field around its own coil turns. When this emf is induced in the same circuit in which the current is changing this effect is called Self-induction (L).
However, when the emf is induced into an adjacent coil situated within the same magnetic field, the emf is said to be induced magnetically, inductively or by Mutual induction, symbol (M ). Then when two or more coils are magnetically linked together by a common magnetic flux, they are said to have the property of Mutual Inductance.
Mutual Inductance is the basic operating principal of the transformer, motors, generators and any other electrical component that interacts with another magnetic field. Then we can define mutual induction as the current flowing in one coil that induces a voltage in an adjacent coil.
