Based on some suppositions on ideal electromagnetic analogy conditions, this paper analyzed the theoretical expression for the time domain IP field intermediate gradient method. The frequency domain data-processing method of the gravity magnetic field was employed to interpret the IP data, and some practical examples were used to make calculation, in the hope that the train of thought and method for IP exploration interpretation can be broadened.
