Q5 · Physics

Consider a long solenoid of length ll and radius r. If n is the number of turns per unit length and μ0\mu_0 is the permeability of free space, the inductance of the solenoid is :

  1. 1μ0πn2r2l\mu_0\pi n^2r^2lOfficial answer
  2. 2μ0n2r2l\mu_0 n^2r^2l
  3. 3(μ0/2π)n2r2l(\mu_0/2\pi)n^2r^2l
  4. 42μ0πn2r2l2\mu_0\pi n^2r^2l
