Mutual inductance | Definition, Calculation & Characteristics
Mutual Inductance. Mutual induction is a phenomenon in which a change in the current flowing through one coil (called the primary coil) induces an electromotive force (EMF) in another nearby coil (called the secondary coil). This occurs due to the magnetic coupling between the coils, as the magnetic field generated by the primary coil interacts
