1. The problem statement, all variables and given/known data A solenoid is wound with a single layer of insulated copper wire of diameter 2.100 mm and has a diameter of 3.000 cm and is 1.900 m long. Assume that adjacent wires touch and that insulation thickness is negligible. a) How many turns are on the solenoid? Solved: determined to be 904 b)What is the inductance per meter (H/m) for the solenoid near its center? 2. Relevant equations Inductance = (constant mu0)* (N^2)*A / l mu0 = 4*PI*10^-7 N = 904 turns A = PI*R^2 (R = 2.100 mm/2) l = length of solenoid = 1.900 m 3. The attempt at a solution Plugged all those variables above (converted R to meters) and got 0.00019 for the inductance. I don't understand what it means to find the Inductance per Meter at the center of the solenoid? Do I have to divide by 1.900 m again? Confused as to what I'm supposed to do.
