电磁学教学中右手(螺旋)定则的应用

Application on Right Hand(Spiral)Rule in Electromagnetics Teaching

在电磁学的教学中,常常用到右手螺旋定则,而在中学的物理教学中常常有左手定则、右手定则.为了避免左、右手的混淆,我们在大学电磁学和大学物理的教学过程中,只强调右手（螺旋）定则,以下文章内容将物理学中使用右手定则的内容加以归类比较,并结合数学的叉乘,有利于学生对此类问题的学习.

In the teaching of electromagnetics, often use the right hand spiral rule, and in：the middle school physics teaching often have a left hand rule, the right - hand rule. In order to avoid the confusion of left and right hand, we electromagnetism in university and college physics teaching process, the emphasis on the right han＇d （spiral） rule, only the following article will use the right-hand rule in physics by sorting out the contents of comparison, combined with the mathematical cross - product, beneficial to this kind of problem with the student learning.
