近年来,带电粒子在电磁场中的运动问题经常以高考模拟卷压轴题的“身份”出现.试题融合了物理学科内的动力学关系及功能关系的考查以及对学生数学应用能力的考查,因此,此类问题总是层出不穷.命题者也一直在尝试设计一些背景新颖、图形美观、学科综合性强的试题.但是笔者发现,也有一些试题在追求背景新颖的过程中,忽略了电磁场存在的科学
In recent years, the movement problem of charged particles in the electromagnetic field often appears in the “identity ” of the simulated scroll axis of the college entrance examination.The test questions combine the dynamic relationship and the functional relationship within the physics discipline and the examination of students’ mathematical application ability, Therefore, such issues are always emerging.People who have been trying to design some new, beautiful graphics, subject comprehensive test.But the author found that there are some questions in the pursuit of novel background, ignoring the existence of electromagnetic fields science
