Question
Self-inductance of a long solenoid is directly
proportional to:Solution
The self-inductance L of a solenoid is given by the formula: 
Where,  μ0 is the permeability of free space, N is the number of turns, A is the cross-sectional area of the solenoid, l is the length of the solenoid. Therefore, the self-inductance is directly proportional to the square of the number of turns.
