贵刊2005年第2期刊登的一篇文章《磁铁断裂处相互间的作用的探讨》认为磁体断裂后,以断裂处的两个端部进行相互作用,对不同磁体而言,可能结果是相互吸引,或是相互排斥。这两种不同结果值得讨论,相互吸引似乎是正常的,而相互排斥,则感到意外。后一种现象在学生进行课外探究性学习中偶有遇到,令学生困惑不解。如何解释这种现象,该文作者进行了一番探讨,但我觉得文章并没有解决实质性的问题,没有把道理讲清楚。 In an article published in the 2nd issue of your magazine “Exploration of the Interaction of Magnet Breakages”, it is believed that after the magnet is broken, the two ends of the fracture are interacted with each other. For different magnets, the result may be mutual. Attract, or mutually exclusive. These two different results are worth discussing. It seems to be normal to attract each other, but it is surprising to be mutually exclusive. The latter phenomenon was occasionally encountered in students’ extracurricular inquiry learning, which puzzled students. How to explain this phenomenon, the author of this article has been discussed a lot, but I think the article does not solve the substantive issues, did not explain the truth.
