Before defining inductance first of all, we will define an inductor.
Like capacitor, inductor is another component commonly in electronic circuits.
An inductor consists of a coil wound on a core or former of a suitable material like solid or laminated iron. core or ferrites which are highly ferromagnetic substances.
when a current through an inductor changes am emf is induced in it which opposes this change of current in the inductor.
This property of inductor or coil due to which it opposes change of current through it called the inductance denoted by letter L.
