摘　　要：磁场测量是磁性测量的重要内容 ,常用方法有电磁感应法。在大学物理实验课中开设的磁场测量内容 ,一般都采用冲击电流计法或霍尔效应法。但这种方法只能用来测量由直流电流产生的稳恒磁场。掌握测量低频交变磁场的原理和方法 。The measuring of magnetism constitutes the main task in the measuring of mangetic field.Electromagnetic induction is often used for this purpose.The method introduced to the college physics experiments class is usually either Baqllistic method or Hall effect method.But they can be applied to measure the stable magnetic field by direct current.Students' command of the fundamental and method for the measuring of Bass frequency alternating magnetic field can play a significant role in broadening their knowledge of magnetic field measuring and in improving their practical skills.
