Abstract: In this paper, the solution of magnetization intensity J(α,β)on imaginary magnetic dipole layer was obtained by the represantation of dipole layer field density component which was regarded as the first kind Fredholm intergral equation and the potential data on the rectangle grid point was computed by the solution J(α,β)which was taken into the represantation. It realizes gridding the scattered potential data which keep the physical character of potential data.

Key words: dipole layer field density component, scattered data, solution of intergral equation
