MAGNETOMETER Russian patent published in 2003 - IPC

FIELD: measurement of stationary and alternating magnetic field. SUBSTANCE: novelty is that magnetometer is provided in addition with electronic integrator, reference-voltage source, ferromagnetic core producing ferromagnetic resonance signal in stationary field under measurement when this core is in saturated state and signal of alternating field under measurement when it is in partially saturated state. Using ampoule with ferromagnetic core instead of that with working materials producing electronic paramagnetic resonance and nuclear magnetic resonance signals has made it possible to extend field measurement range from 10^-13 to 16 T and to enlarge frequency range up to 200 kHz using single measuring device. EFFECT: enlarged measurement range for weak and very weak fields. 2 cl, 2 dwg
