APPARATUS FOR MEASURING DENSITY OF VARIABLE MAGNETIC FIELD

摘要

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
