初、高中物理都提到了磁化小实验，高级中学物理图１第二册教学参考书具体介绍了用条形磁铁磁化钢锯条的方法：按图１所示，用强磁铁的一个极沿钢锯条Ａ的侧面由一端向另一端多次定向运动，使Ａ较好地磁化．用安培分子电流假说容易解释磁化现象．钢锯条内部的微观分子电流...
The physics of junior and senior high schools all referred to the magnetization experiment. The second high school physical map teaching reference book specifically introduced a method of magnetizing a hacksaw blade with a bar magnet: as shown in Fig. 1, a pole of a strong magnet was used along the hacksaw blade. The side of A is oriented multiple times from one end to the other, making A well magnetized. The magnetization phenomenon is easily explained by the amperometric molecular current hypothesis. The microscopic molecular current inside the hacksaw...
