MAGNETORESISTIVE PICKUP Russian patent published in 2003 - IPC

FIELD: automatics, devices measuring direct and alternating currents and voltages where resistance decoupling of signal source and measuring instrument is required. SUBSTANCE: magnetic system comprising several permanent micromagnets forming homogeneous magnetic field in strips in plane of their arrangement and perpendicular to their axis of light magnetization is positioned in plane of magnetic strips. EFFECT: design of pickup measuring direct and alternating currents displaying low value of hysteresis and expanded range of linear working section. 3 dwg
