传统磁场测量和安培力测量实验仪器是完全独立的，本文将 Arduino

单片机与霍尔传感器应用于大学物理实验，设计并制作一种可以测量载流圆线圈、亥姆霍兹线圈、螺线管等产生的磁场空间的分布且可对安培力大小进行定量研究的综合实验仪.磁感应强度和安培力大小可通过显示屏直接读出，方便快捷.

该综合实验仪拓展了研究磁场分布和安培力大小影响因素的实验教学内容，有利于加深学生对物理知识的理解，培养学生创新思维，激发学习物理的兴趣，培养创新型人才.

 The measurement of traditional magnetic field and Ampere force are carried out on

completely inde- pendent experimental instruments. In this paper，Arduino MCU and Hall sensor

are applied to university physics experimental instruments，and a kind of comprehensive

instrument is designed and manufactured to measure the distribution of magnetic field and

the Ampere force caused by the current carrying circular coil，Helmholtz coil and Hall sensor. The

magnetic induction intensity and Ampere force can be read through the display screen

directly， conveniently and fast. The experimental teaching principles and contents of studying the

influence factors of magnet- ic field distribution and Ampere force are expanded，which is helpful

for students to deepen their understanding of the application and practice of physical

knowledge，cultivate students’innovative thinking and stimulate their inter- est in learn.
