Question 235: Electromagnetic Induction

Question

A graph of magnetic flux $(\phi)$ versus current (I) is shown for 4 different inductors $\mathrm{P}, \mathrm{Q}, \mathrm{R}, \mathrm{S}$. Minimum value of inductance is for inductor

Accepted Answer

Flux, $\phi=$ LI
Comparing the above equation with $\mathrm{y}=\mathrm{mx}$, $\mathrm{L}=\phi / \mathrm{I}$, which is the slope of the graph.
Since line S has least slope, it indicates the smallest value of self-inductance.
