METHOD OF MEASURING MAGNETIC CONDUCTIVITY OF CYLINDRICAL FERROMAGNETIC CONDUCTORS Russian patent published in 2005 - IPC

Abstract RU 2255346 C2

FIELD: measurement technology.

SUBSTANCE: cylindrical conductor with radius of r and specific conductivity of δ is connected to secondary winding of step-down transformer through reference resistor. Primary winding of step-down transformer is connected with ac generator with f frequency. Longitudinal resistance Z of tested cylindrical conductor is measured at 1-meter length section. Magnetic conductivity μ is determined from the relation of μ=(Z²r²υ)/(2f10‾⁷).

EFFECT: reduced labor-intensity due to measurement of conductor's resistance.
