MAGNETIC MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a novel magnetic measuring device for measuring a slight magnetic quantity. SOLUTION: This magnetic measuring device comprises one or more two-dimensional rotation centers; one or more magnetic field generators generating a magnetic field in the normal direction relative to the rotation center; one or more magnetic sensors to be set vertically to the magnetic field; and one or more sample setting tables for mutually opposing the magnetic sensor and a sample to be measured for magnetic field to confront to the two-dimensional rotation center. The magnetic field generator and/or the magnetic sensor have a driving function for relatively rotating the sample around a selected rotating center to draw a two-dimensionally concentric circle. This measuring device further comprises a signal processor for converting a magnetic measurement signal from the magnetic sensor to a usable form. COPYRIGHT: (C)2005,JPO&NCIPI
