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?
