摘要
物理课是中学阶段非常有趣的一门课程,其中讲述的很多现象都与我们的现实生活联系紧密,很多现象不仅可以通过实验展示,而且还能通过数学公式的推导揭示其奥秘。物理中关于"磁场"的讲述,引起了笔者很多的联想,并由此产生了很多的疑问,通过利用磁场的物理表达和数学中的向量合成等知识,对空间两个相同线圈产生"圆形旋转磁场"的条件进行了探究,得出了相应的结论,并利用磁场的模拟演示和电磁场仿真软件的计算对圆形旋转磁场的产生进行了验证。
Physics class is an interesting course, which is mostly related to the phenomena close to our lives. And many phenomena can not only be shown experimentally, but also be deduced by mathematical formulas to reveal their mysteries. Experiments are the wings of imagination and mathematics provides a powerful tool for us to study physics course. I have many questions and ideas about the ＂magnetic＂ knowledge in my physics course, such as how the two coils magnetic field can be made to rotate？ And then by using physic expression, vector synthesis of mathematics and electromagnetic simulation software, the circular rotating magnetic field is verified to generate in two coils and shown in simulation demonstration.
