APPARATUS FOR MEASURING DENSITY OF VARIABLE MAGNETIC FIELD Russian patent published in 2002 - IPC

Abstract RU 2178570 C1

FIELD: measuring technique, namely apparatuses for measuring intensity of variable magnetic field. SUBSTANCE: apparatus is provided with additional feedback coil connected in parallel with measuring coil. Outlet of amplifier is loaded to series connection of feedback coil with first resistor whose output voltage is applied to inverting inlet of amplifier through aperiodic unit having second and third resistors and additional capacitor. EFFECT: enlarged frequency range and high response of measurements. 1 dwg
