Answer 1

Explanation:

Let's take a worked example to find the inductance for the winding shown with just two turns (N=2).

Σl/A = le / Ae = 27.6×10-3 / 19.4×10-6 = 1420 m-1

μ = μ0 × μr = 1.257×10-6 × 2490 = 3.13×10-3 Hm-1

Rm = (Σl/A) / μ = 1420 / 3.13×10-3 = 4.55×105 A-t Wb-1

Al = 109 / Rm = 109 / 4.55×105 = 2200 nH per turn2

L = Al × N2 = 2200 × 10-9 × 22 = 8.8 μH
