What is its inductance? b) How many turns would you need to generate the same inductance if the core were iron filled insted ? assume the magnetic permeability of iron is about 1200 times of that free space
An air filled cylinder has 2800 turns and it is 2.5 cm in diameter and 28.2 cm long
Homework Answers
a)
indutance = eo N^2 A /L
i = 4 x 3.14 x 10^-7 x 3200^2 x 3.14 x .0125 ^2 / .299
i = 21.11 mH
b)
21.11 = k 3200^2
21.11= 1200 k N^2
N = 1.63 = 2 turns
