摘　　要：本文分析研究了瞬变电磁法中垂直磁场的基本物理特性 ;给出了基于垂直磁场的全区视电阻率定义 ;The basic physical characteristics of vertical magnetic fields for Transient Electromagnetic Method （TEM） have been discussed in this paper. Then the whole-time apparent resistivity is defined based on normalized vertical magnetic field. The advantages for directly measuring magnetic field are illustrated by comparing with the measurement of EMF using induction coil.
