Abstract

Families of dependences of the parameters of magnetic induction, permeability, susceptibility, and magnetization for cylindrical steel samples on the field strength H and the ratio of their length to diameter L/D are obtained. It is shown that the dependences of these parameters on L/D reach self-similarity regions (thereby proving the correspondence to the magnetic properties of the material) at different H-dependent L/D values, in contrast to the existing opinion. It is also shown that the range of L/D samples used in practice is characterized by an exponential relationship between their demagnetizing factor and L/D.

不同长度铁磁样品的磁性,退磁系数的近似值

摘要

获得了圆柱钢样品的磁感应强度、磁导率、磁化率和磁化强度参数对场强H及其长径比L / D的相关性族。结果表明,与现有观点相反,这些参数对L / D 的依赖性在不同的H依赖L / D值下达到自相似区域(从而证明与材料的磁性的对应关系)。还表明L / D的范围实际使用的样品的特点是它们的退磁因子与L / D之间呈指数关系。
