- Abstract:
- The fundamental factors that limit the accuracy of magnetic measurements for field strengths typically encountered in industrial measurements of permanent magnets are discussed. In regions where magnetic fields can be considered homogenous, the accuracy of the measurement is limited by the stability of the magnetometer, the accuracy of its calibration, and the orthogonality of the sensor. However, the fieldsensitive volume's size and the measurement axis’s orthogonality determine the total accuracy in the nearfield region of small magnetic structures. Using measured magnetic images from encoder structures, it is shown that accurate measurements are achieved only by measuring all 3 magnetic field components in a tiny volume.
