Physics - EMI/AC Question with Solution | TestHub

Let us consider two solenoids $A$ and $B$, made from same magnetic material of relative permeability ${\mu }_r$ and equal area of cross-section. Length of $A$ is twice that of $B$ and the number of turns per unit length in $A$ is half that of $B$. The ratio of self inductances of the two solenoids, $L_A:L_B$ isNEET 2024 (Re-NEET)
