METHOD FOR DETERMINING MAGNETIC PERMEABILITY OF CYLINDRICAL FERROMAGNETIC CYLINDRICAL CONDUCTORS |
| 摘要 |
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 mu=(Z2r2sigma/2f10-7)e-j*2(45-&phis;). ^ EFFECT: high accuracy of measurement. ^ 1 dwg |
