Question

The total number of turns and cross-section area in a solenoid is fixed. However, its length L is varied by adjusting the separation between windings. The inductance of solenoid will be proportional to:

TestHub · Accepted Answer

Self-Inductance = μ 0 n 2 π r 2 L (n = number of turns per unit length) = μ 0 N L 2 π r 2 L = μ 0 N 2 π r 2 L Self-Inductance ∝ 1 L
