用有限元方法计算了方棒的磁通退磁因子N/subf/和N/subm/，它们是磁化率/Spl chi/和长宽比c/a在/Spl chi/=-1 to/Spl Infin/和c/a=0.01-100范围内的函数。我们用数字和表格给出了结果，并将它们与圆柱体的结果进行了比较。给出了立方体的N/subm/(/spl chi/)的一个近似共轭关系。
Using a finite-element method, we have calculated fluxmetric and magnetometric demagnetizing factors N/sub f/ and N/sub m/ for square cross-section bars as functions of susceptibility /spl chi/ and length-to-width ratio c/a over the range /spl chi/=-1 to /spl infin/ and c/a=0.01 to 100. We present the results in figures and tables and compare them with those for cylinders. We give an approximate conjugate relation for N/sub m/(/spl chi/) of a cube.
