Difference between Self inductance and Mutual inductance

Difference between Self and Mutual inductance

Self inductance is the property of a single isolated coil to induce emf  in accordance with the change in magnetic flux linked with it. Mutual inductance of a pair coils is the ability of one coil to produce an induced emf in nearby coil when the magnetic flux linked with it . The difference between them is as follows.

                  Self inductance  

                          Mutual inductance

1)      In the same coil emf produces through the coil to changes current flow known as self inductance.

2)      The characteristics of a coil itself is the self inductance.

3)      When the main current in the coil decreases, the induced current opposes the decay of current in the coil.

4)      When the main current in the coil increases the induced current opposes the decay of current in the coil.

5)      Relation of the self inductance is:

       Φ = LI

6)      Formula of the self inductance is:

L=N Φ/I

1)      The phenomenon of the mutual induction change in the current or magnetic flux link with two coils an opposing electromotive force produced across each coil.

2)      The characteristics pairs of coils is the mutual inductance.

3)      When the main current in the coils decreases, the induced current developed in the neighbouring coil opposes the decay of the current in the coil.

4)      The main current in the coil increases, the induced current developed in the neighbouring coil opposes the growth of current in the coil.

5)      The relation of the mutual inductance is:

         = MI.

6)      Formula of the mutual inductance is :
