左手定则、右手定则和右手螺旋定则是中学物理电磁部分的重要定则。学生在单独应用这三个定则时尚能正确使用,但在综合应用这三个定则解答问题时,出现模棱两可现象,学生常会把这三个定则混淆,记忆混乱,导致解题错误。鉴于此,笔者将这类问题进行收集整理,将知识点进行拓展,提出右手螺旋统一化原则,便于学生记忆,提高判断方向的准确率,从而提高教学质量。由于中学物理范围内还未讲解太 The left-hand rule, the right-hand rule, and the right hand helix rule are important rules for the secondary electromagnetic physics. The students can correctly use these three rules when they are applied alone. However, when applying these three rules to answer the questions, they are ambiguous. Students often confuse these three rules and confuse their memory, leading to mistakes in solving problems. In view of this, the author collects and sorts these kinds of questions, expands the knowledge points, puts forward the principle of unification of the right hand spiral, facilitates the students’ memory, improves the accuracy of judgment direction and improves the teaching quality. Due to high school physics has not yet explained too much
