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
  1. A
  2. D
  3. C
  4. B

Solution

We have $\phi=L I$ or $L=\frac{\phi}{l}$ Self-inductance is given by the slope of the graph; slope of line A has the maximum value and therefore, largest self-inductance. ^
