Abstract

Formulas are given for calculating the strength of the resulting magnetic field due to magnets with a given magnetization distribution or immersed in a given field of external sources. These are the cases when the calculation using these formulas can be performed by a user who does not have much experience in the field of computational mathematics and programming. Namely, in these cases, the formulas for intensity are mostly expressed in closed form in terms of elementary functions or require the use of one of the standard routines available in the library of any programming language. Such formulas can serve as a reference material as well as for solving relevant problems with suitable real objects or for determining optimal strategies and an optimal set of input parameters when using universal software packages and estimating the error of the results obtained.

置于外部磁场中的磁铁所产生的磁场强度的一些显式表达案例
给出了计算具有给定磁化分布的磁体或浸入给定外部磁场的磁体所产生的磁场强度的公式。在这些情况下,使用这些公式进行计算的用户在计算数学和编程领域没有太多经验。也就是说,在这些情况下,强度公式大多以基本函数的封闭形式表示,或者需要使用任何编程语言库中的一个标准例程。这些公式可作为参考资料,也可用于解决与合适的实际对象相关的问题,或在使用通用软件包时确定最佳策略和最佳输入参数集,以及估计所获结果的误差。

期刊介绍: Russian Journal of Nondestructive Testing, a translation of Defectoskopiya, is a publication of the Russian Academy of Sciences. This publication offers current Russian research on the theory and technology of nondestructive testing of materials and components. It describes laboratory and industrial investigations of devices and instrumentation and provides reviews of new equipment developed for series manufacture. Articles cover all physical methods of nondestructive testing, including magnetic and electrical; ultrasonic; X-ray and Y-ray; capillary; liquid (color luminescence), and radio (for materials of low conductivity).
