摘要
阐述了退磁的原理及常用的退磁方法,对当前用到的几种退磁方法进行评述,主要针对直流退磁、交流退磁以及加热退磁的效果进行了分析。
This paper expounds demagnetization principles and ihe common used demagnetization methods. Several present popular demagnetization methods have been evaluated and their effects have been analyzed, which focuses on direct currenl demagnetization, alternating current demagnetization and pyrogenation demagnetization.
