COIL FOR MAGNETIC FIELD DETECTION, METHOD OF MANUFACTURING COIL FOR MAGNETIC FIELD DETECTION, COMBINATION COIL FOR MAGNETIC FIELD DETECTION AND MAGNETIC FIELD MEASURING INSTRUMENT

摘要

PROBLEM TO BE SOLVED: To high-densely arrange a number of coils for magnetic field detection.;SOLUTION: The magnetic field measuring instrument is provided with a first coil 1-z for weak magnetic field detection for detecting a magnetic field in the z-axis direction, a second coil 1-x for weak magnetic field detection coaxially arranged on the outer peripheral side of the first coil for detecting a magnetic field in an x-axis direction and a third coil 1-y for weak magnetic field detection coaxially placed on the outer peripheral side of the second coil for detecting a magnetic field in a y-axis direction. Thereby, since the instrument can be formed into one cylinder as a whole and magnetic fields in two directions of the axial direction of the cylinder and an orthogonal direction thereof can be detected, a number of coils for magnetic field detection can be high-densely placed, A magnetic field vector quantity can be measured at a single observation point.;COPYRIGHT: (C)2004,JPO
