Abstract

The measurement system with rotation mechanism is designed and built to measure the orientation angle of permanent magnets. The system based on the measurement of magnetic moment with Helmholtz coils is applicable to the magnets with different shapes and sizes. The measurement uncertainty of the orientation angle is 0.23° (k=2). The two dimensional (2D) method is proposed to substitute for the three dimensional (3D) method to improve the measurement efficiency.
