Vedclass · Answer

(A) The self-inductance $L_{ind}$ of a solenoid is given by the formula $L_{ind} = \frac{\mu_0 N^2 A}{l}$,where $N$ is the total number of turns,$A$ is the cross-sectional area,and $l$ is the length of the solenoid.Given that the total number of turns $N$ and the cross-sectional area $A$ are fixed (constant),the expression becomes $L_{ind} \propto \frac{1}{l}$.Therefore,the inductance of the solenoid is inversely proportional to its length $L$.

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