Solution
A graph of magnetic flux `(phi)` versus current (I) is shown for four inductors A, B, C and D. Larger value of self-inductance is for inductor A.
Explanation:
`"We have" phi = "LI" or "L" = phi/"I"`
self-inductance is given by the slope of the graph. Slope of line A is maximum hence it gives maximum value of self inductance.
