Vedclass · Answer

(C) The self-inductance $L$ of a solenoid is given by the formula $L = \frac{\mu_0 N^2 A}{l}$,where $\mu_0$ is the permeability of free space,$N$ is the number of turns,$A$ is the cross-sectional area,and $l$ is the length of the coil.From this expression,it is clear that the self-inductance $L$ is directly proportional to the square of the number of turns,i.e.,$L \propto N^2$.

If $N$ is the number of turns in a coil,the value of self-inductance varies as
