Answer 1

$\mu$ = permeability of free space = 4$\pi$ x 10^-7 H/m

N = number of turns = 8800

A = area of cross-section of the coil = $\pi$ r²

r = 0.027/2 = 0.0135 m

l = length of coil= 0.60 m

inductance of a solenoid:

L = $\mu$ *A*N²/l

L = (4$\pi$ x 10^-7)*(8800)²* {(3.1415)(0.0135)² }/ (0.60)

L = 0.0928 H
