An air-filled cylindrical inductor has 2600 turns. It is 2.4 cm in diameter and 28.5 cm long.(a) What is its inductance? _____________H(b) How many turns would you need to generate the same inductance if the core were filled with a material instead of air? Assume the magnetic permeability of this material is 1700 times that of free space. _________turns
hyperphysics.phy-astr.gsu.edu/hba a) Solenoid length 28.5 cm with N 2600 turns, Coil radius r 1.2 cm gives area A 4.52389 cm2. Relative permeability of the core k 1 (air) Then the inductance of the solenoid is B 0.013484 Henry 13.484 mH. b) Number of turns 2600 / √ 1700 63 turns hyperphysics.phy-astr.gsu.edu/hba Goodbye
