Magnetic recording system require to increase capacity of memory, record at high speed and reduce power consumption. In recent years, a microscopic magnet is used on magnetic disc and accurate position control of magnetic head is performed in magnetic recording system, which make it possible to increase capacity of memory and record at high speed. Power consumption is changed by electric current. In fact, control of electric current is related to control of magnetic flux, which affect capability of recording. However, researches on magnetic flux focused on control of electric current have not been carried out sufficiently. In the analysis of magnetic field based on the finite element method, it is necessary to consider continuity of the magnetic flux density of normal direction on the interface among element. The node element does not satisfy this condition, however the edge element contain it. In this paper, the edge element is introduced based on mathematical theory, and basic example is carried out.
