A graph of magnetic flux $(\oint)$ versus current (I) is shown for four inductors A, B, C and D. Larger value of self-inductance is for inductor
  1. D
  2. B
  3. C
  4. A

Solution

We have $\phi=\mathrm{LI}$; or $\mathrm{L}=\frac{\phi}{\mathrm{I}}$, hence it gives self-inductance is given by the slope maximum value of self inductance.
