A graph of magnetic flux $(\phi)$ versus current (I) is plotted for four inductors A, B, C, D. Larger value of self inductance is for inductor
A
B
C
D
Solution
From $\phi=\mathrm{LI}$
Comparing the above equation with $\mathrm{y}=\mathrm{mx}$, $\mathrm{L}=\phi / \mathrm{I}$, which is the slope of the graph.
Since line A has highest slope, it indicates the largest value of self-inductance.
