The coefficient of self-inductance explained class 12th ,

Definition and Concept
Inductance (
L
L) is defined as the property of a conductor by which a change in current through it induces an electromotive force (emf) or voltage in both the conductor itself and any nearby conductors. This induced emf opposes the change in current according to Lenz's Law.
Physical Explanation
When an electric current
I
I flows through a conductor, it creates a magnetic field around the conductor. The magnetic flux (
Φ
Φ) produced by this current depends on the strength of the current and the geometry of the conductor. According to Faraday's Law of Electromagnetic Induction, any change in this current will induce an emf in the conductor itself.
The coefficient of self-inductance (
L
L) is directly proportional to the magnetic flux
Φ
Φ produced by the current flowing through the conductor
