Abstract

PURPOSE: To make possible easy and accurate determination of the direction of the main stress by turning a magnetic sensor for detecting the iron loss corresponding to the stress around the measuring points of the magnetic material in the measurement.
CONSTITUTION: As the magnetic sensor 2 for detecting the iron loss corresponding to the stress thus around the measuring points of the magnetic material 7, points B,B' and B" and the like equal in the iron loss are detected. The direction of the main stress can be determined accurately with ease by finding the direction of the bisectors of the angles α1-α2, α2-α3 and the like based on the turning angles α1, α2, α3 and the like corresponding to these points B, B', B" and the like, Therefore, the magnitude of the main stress can be obtained accurately from the iron loss detected orthogonal to the main direction.
