Mutual Inductance between the two coils is defined as the property of the coil due to which it opposes the change of current in the other coil, or you can say in the neighboring coil. When the current in the neighboring coil is changing, the flux sets up in the coil and because of this changing flux emf is induced in the coil called Mutually Induced emf and the phenomenon is known as Mutual Inductance.
The value of Mutual Inductance (M) depends upon the following factors
*-Number of turns in the secondary or neighboring coil
*-Cross-sectional area
*-Closeness of the two coils
Mutual Coupling In the Magnetic Circuit
When on a magnetic core, two or more than two coils are wound the coils are said to be mutually coupled. The current, when passed in any of the coils wound around the magnetic core, produces flux which links all the coils together and also the one in which current is passed. Hence, there will be both self-induced emf and mutual induced emf in each of the coils.
-The best example of the mutual inductance is a transformer, which works on the principle of Faraday’s Law of Electromagnetic Induction.
Faraday’s law of electromagnetic induction states that “ the magnitude of voltage is directly proportional to the rate of change of flux.” which is explained in the topic Faraday’s Law of Electromagnetic Induction.
