Impedance Analysis of a Solenoid Eddy Current Coil with Cylindrical Two - conductor Rods |
| Abstract |
Somo analytic results for a solenoid eddy current coil to test nondestructively conducting materials are described in this paper. Normalized impedance of solenoid coil encircling cylindrical conducting tubes or two-conductor reds is analyzed. Electrical and magnetic properties such as conductivity, permeability and exciting frequency as well as the geometric ones of fill factor or radius ratio of the conductor are also considered. Impedance characteristics of the models obtained by numerical analysis are examined. Validation of the models is carried out using several samples of non-ferromagnetic conducting tubes and 2-conductor rods. |
