本文研究了均匀磁化多面体的磁场,建立了包括各个磁场分量(H_(ax)、H_(ay)、Z_(a)和△T)的规格化解析式。它是由平表面围成的任意磁性体的一般表达式。由它可以简化出各种简单磁性体的公式。文中以有限长倾斜板状体磁场为例,说明了这个化简过程。本文的多面体磁场解析式,是由角点坐标和磁参数值表示出来的,鉴于它是边和面的二重累加求和,在电子计算机上计算是十分方便的。
In this paper, we study the magnetic field of a uniformly magnetized polyhedron and establish a normalized analytic formula that includes all the magnetic field components (H_ (ax), H_ (ay), Z_ (a) and △ T) It is a general expression of any magnetic body surrounded by a flat surface. It simplifies formulas for a variety of simple magnetic bodies. In this paper, a finite length tilted plate-shaped body magnetic field, for example, illustrates this simplification process. In this paper, the analytical formula of the polyhedral magnetic field is expressed by the coordinates of the corner points and the values of magnetic parameters. Given that it is a double summation of edges and surfaces, it is very convenient to calculate on the computer.
