Solenoid Self-InductanceEasyQuestion 20176

Question

Self-inductance of a solenoid with n turns/m, length l, area A is:
  1. A
    μ₀n²Al
    Correct
  2. B
    μ₀nAl
  3. C
    μ₀nA/l
  4. D
    μ₀n²A/l

Correct answer

μ₀n²Al

Explanation

L = μ₀n²V where V = Al is the volume. So L = μ₀n²Al. For a solenoid with N total turns: L = μ₀N²A/l.
