How does the self-inductance of a coil depend on the number of turns of the coil?

Self-inductance(L) of a coil depend on the number of turns(N) of the coil. Where self inductance is directly proportional to square of the number of turns. L ∝ N 2 . Here self inductance is represented by L, and Number of turn is represented by N.
