Question 213: Electromagnetic Induction

Question

A graph of magnetic flux $(\phi)$ versus current $(I)$ is shown for four inductors $\mathrm{P}, \mathrm{Q}, \mathrm{R}, \mathrm{S}$. The largest value of self-inductance is for inductor

Accepted Answer

Flux, $\phi=\mathrm{LI}$
Comparing the above equation with $\mathrm{y}=\mathrm{mx}$, L is the slope of the graph.
Since line P has highest slope, it indicates the largest value of self-inductance.
