A solenoid is wound with a single layer of insulated copperwire of diameter 2.500 mm and has a diameter of 5.000cm and is 1.800 m long. Assume that adjacent wirestouch and that insulation thickness is negligible.
a)How many turns are on the solenoid?
b)What is the inductance per meter (H/m) for thesolenoid near its center?

N(2.5103m)=1.8m
number of turns N=720
number ofturns per unit lengthn=7201.8=400
Ll=μ0n2A=μ0n2Π(r2)
=(1.26106)(400)2Π(r2)
=(1.26106)(400)2Π(2.5100)2
inductance per meter =0.09896103Hm
