Question 307: Electromagnetic Induction

Question

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

Accepted Answer

Draw a line parallel to $$\phi$$ axis
$$\because \phi=\mathrm{LI} \quad 	herefore \mathrm{L}=\frac{\phi}{\mathrm{I}}=$$ slope of $$\phi-\mathrm{I}$$ curve
$$	herefore$$ We find that the slope is maximum for A
$$	herefore$$ A has the maximum self inductance as OP is same for all.
