Abstract

An analysis of accuracy of asymptotic method for three-dimensional pulse electromagnetic field created by arbitrary current contour, which is located near the flat surface of a conductive body are made. Values of time intervals by which separate terms of series limited are received. Comparison with exact values has shown possibility considerably to simplify calculation at the initial stage of pulse process. References 3, figures 3.

 

Key words: pulse electromagnetic field, eddy current, arbitrary current contour, asymptotic method.
