摘要

利用智能手机的指南针功能，结合亥姆霍兹线圈产生的均匀磁场，来进行普通物理实验中地球磁场水平分量的测量实验的改造。充分利用了手机的指南针的灵敏度高、无偏心误差以及读数准确的优点，减小了实验误差。同时，提高了利用生活中的常用工具来解决物理问题、激发学生学习兴趣的目的。

Abstract:

Using the compass function of smart phone and the uniform magnetic field generated by Helmholtz coil, the horizontal component measurement experiment of the earth's magnetic field in common physics experiment is reformed. The advantages of high sensitivity, no eccen- tricity error and accurate reading of the compass of the mobile phone are fully utilized, and the experimental error is reduced. At the same time, it improves the purpose of using common tools in life to solve physics problems and stimulate students' interest in learning.

Key words: Helmholtz coil compass geomagnetic field
