In order to improve the resolution of the electromagnetic induction exploration,a new method,based on three dimensional coils,is developed to accurately measure the ellipticity of total magnetic field. It overcomes the defects of traditional methods and makes a new way for the high resolution electromagnetic exploration. This paper introduces its configuration and provides its mathematical calculating procedure by analyzing the spatial distributing characteristics of complex magnetic field. Additionally the calculating method has its theory value.
