Abstract
In order to display magnetic signals obtained from a magneto-resistance sensor, a direct current magnetometer was designed and its circuit was constructed. The magnetic fields measured by the home-made magnetometer, which showed good functions of automatic ranging, analog output, and vector sensing, were well agreed with those by commercial MAG-01 magnetometer. The measurement range of the magnetometer was
자기저항 센서로부터 얻은 자기 신호를 표시하기 위하여 직류 자력계를 설계하고, 그 회로를 구현하였다. 제작한 자력계 및 상용 MAG-01 자력계로 측정한 자장은 서로 잘 일치하였고, 제작한 자력계의 자동 범위선택기능, 애널로그 출력기능 및 벡터 감지기능이 양호하였다. 자력계의 측정범위는
