The plot of magnetic flux ' ' linked with the coil versus current ' I ' is as shown in figure for two inductors L₁ and L₂ . The self inductance of

Options

  1. AL ₁ is equal to that of L ₂ .
  2. BL₁ is less than that of L₂ .
  3. CL₁ is greater than that of L₂ .
  4. DL₁ is half that of L₂ .

Correct answer

C. L₁ is greater than that of L₂ .

Step-by-step solution

The magnetic flux through a coil relates to the current I by = LI , where L denotes the self-inductance. On a vs. I graph, this is a linear equation of the form y = mx , so the slope corresponds to L . Since the line for L₁ is steeper than that for L₂ , its slope—and thus its self-inductance—is greater. Therefore, L₁ > L₂ . The correct choice is C .
