带电粒子在磁场中的运动一直是高考的重点考查内容,同时,它也是高中生在学习中的重难点知识。带电粒子在有界磁场中的运动、带电粒子在磁场中运动时的极值问题等,都是让很多高中生感到头疼的问题。因此,必须找到有效的带电粒子在电磁场中运动的解决方法,才能帮助高中生克服学习难点。其中,动态圆是一种有效的方法。对如何利用动态圆来解决带电粒子在电磁场中的运动进行研究与分析。
The movement of charged particles in the magnetic field has always been the focus of the entrance exam, at the same time, it is also a heavy and difficult point in high school students learning knowledge. Charged particles in a bounded magnetic field in the movement of charged particles in the magnetic field when the extreme problems, are so many high school students feel a headache problem. Therefore, we must find effective solution to the movement of charged particles in the electromagnetic field in order to help high school students to overcome the learning difficulties. Among them, the dynamic circle is an effective method. How to use the dynamic circle to solve the movement of charged particles in the electromagnetic field research and analysis.
