Abstract
Amorphous-core multivibrator bridge circuit systems were studied in single-core and in double-core systems. When the length of the amorphous wire is varied in the range 80 mm to 10 mm, the one-core system detection sensitivity showed small variation in the range 8.5 mV/Oe to 7 mV/Oe, while in the two-core case the sensitivity was high and the variation was 110 mV/Oe to 22 mV/Oe. Zero drift at amorphous wire length of 10 mm is very marked in the one-core system, but magnetic annealing results in stability being reached within 80 min after the power is turned on. In the two-core case stability is reached with 10 min after power is supplied.Keywords
