脉冲场磁强计

[中文适用范围]： 本技术报告回顾了使用脉冲场磁强计测量硬磁材料的方法。硬磁材料磁性能的测量方法已在 IEC 60404-5（闭合磁路）和 IEC 60404-7（开路磁路）中规定。硬磁材料在高温下的磁性能测量结果见 IEC 61807。本报告的目的是描述脉冲场磁测法的原理和实际意义，以便能够充分考虑该技术的潜力，包括将其应用于不同几何形状的小磁体和大磁体，以及不同的磁场强度和频率。 [外文原描述]： Reviews methods for measuring magnetically hard materials using pulsed field magnetometers. The methods of measurement of the magnetic properties of magnetically hard materials have been specified in IEC 60404-5 for closed magnetic circuits and in IEC 60404-7 for open magnetic circuits. The measurement result of the magnetic properties of magnetically hard materials at elevated temperatures is given in IEC 61807. Pulsed field magnetometers have been developed to provide rapid measurement facilities to match high speed production rates with 100 % quality control. The object of this report is to describe the principles and practical implications of pulsed field magnetometry in order to enable the full potential of the technique to be considered, including its application using small and large magnets of varying geometries, to various magnetic field strengths and frequencies.
