摘要
就亥姆霍兹线圈测磁原理作了较为详尽的论述,并且介绍了线圈的尺寸选择原则,最后对磁偶极子模型进行了修正,尽可能地降低了线圈设计的理论误差,对设计较为精确的亥姆霍兹永磁体测量系统有一定的参考意义。
Helmholtz coils is an excellent magnetic measurement system. This paper describes the measurement principle of Helmholtz coils system, and introduces the selection fundamental of coils constant, finally corrects the magnetic dipole model to reduce as possibly the error of coils＇ design. This paper is helpful for designing more precise Helmholtz coils system used to permanent magnetic measurement.
