Question 249: Electromagnetic Induction

Question

A graph of magnetic flux $(\phi)$ versus current ( 1 ) is shown for four inductors A, B, C, D. Smaller value of self inductance is for inductor

Accepted Answer

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 D has lowest value of slope, it indicates the smallest value of self-inductance.
