本文分析了工件中自然缺陷与人工缺陷在选择磁化电流上的区别,同时证明了不同性质的缺陷所产生的漏磁通密度也是不同的。
This paper analyzes the difference between the natural defects and the artificial defects in the selection of magnetizing current, and at the same time, it is proved that the leakage magnetic flux density caused by the defects of different nature is also different.
