| 摘 要： | 在采用霍耳探头测磁场时，必须考虑到探头的自生磁场所引起的测量误差。利用毕奥沙伐定律和镜像法证明了自生磁场对测量螺线管的磁场所引起的误差不能忽略；对测量电磁铁气隙中的磁场的误差可以忽略。

| Abstract: | When the magnetic field is measured using a Hall probe,the measurement error due to the self-producing magnetic field by the Hall probe must be taken into account. By the Biot-Savart law and image method it is shown that the error arising from the influence of the self-producing magnetic field on the measurement of the magnetic field in a solenoid cannot be neglected,and that the error arising from the influence of the self-producing magnetic field on the measurement of the magnetic field in the gap of an electromagnet can be neglected. |
