METHOD FOR DETERMINING MAGNETIC PERMEABILITY OF CYLINDRICAL FERROMAGNETIC CYLINDRICAL CONDUCTORS Russian patent published in 2006 - IPC G01R33/12 G01N27/72

Abstract RU 2288479 C1

FIELD: measurement technology.

SUBSTANCE: method involves determining magnitude and angle of longitudinal resistance to conductor Z under study. The magnetic permeability is determined from relation μ=(Z²r²σ/2f10^-7)e^-j*2(45-φ).

EFFECT: high accuracy of measurement.
