Hey mate your answer is here...
Self induction is that phenomenon in which a change in electric current in a coil produces an induced emf in the coil itself.
MATHEMATICAL REPRESENTATION:
Self induced emf in a coil is directly proportional to the rate of change of electric current in the coil.i.e.
Emf a – DI/Dt
Or emf = -L DI/Dt
Where, L = self inductance of the coil.
SELF INDUCTANCE
Self inductance of a coil is defined as the ratio of self-induced emf to the rate of change of current in the coil.
Self inductance = emf/ DI/Dt
It is denoted by ‘L’ and it depends upon the physical characteristics of the coil.
Unit of self inductance is Henry
Coefficient of self induction - the ratio of the electromotive force produced in a circuit by self-induction to the rate of change of current producing it, expressed in henries.
The phenomena of production of induced emf in a circuit due to change in current flowing in its own, is called self induction. it unit of self induction is henry (H) and its dimensional formula is [ML2T -2A-2]. A = area of cross-section of the coil.
Hope this answer helps you..

SELF INDUCTANCE : SELF INDUCTANCE IS A PROPERTY OF A COIL DUE TO WHICH IT OPPOSSES A CHANGE IN CURRENT THROUGH IT.A CHANGE IN THE CURRENT PRODUCES AN EMF IN THE COIL TO OPPOSSE THE CHANGE ,WHICH IS THE ESSENTIAL PROPERTY OF INDUCTANCE .
SELF INDUCTION : SELF INDUCTION IS
AN ELECTROMAGNETIC PHENOMENON
WITH WHICH IT TRIES TO OPPOSE THE
CHANGE IN THE CURRENT FLOW IN A
WIRE , DUE TO THE MAGNETIC FIELD
ESTABLISHED BY THE SAME CURRENT..
