摘要
采用示波器对感应法测交变磁场实验进行了改进,提高了实验的效果和精度.若已知磁场强度,还可测定真空磁导率.
The induction method for measuring the alternating magnetic field is improved with the oscillograph, the effect and precision of the experiment are improved. If the intensity of the magnetic field is known, the permeability of vacuum can be measured.
