电流的磁场是初中物理的一个重要知识点,也是中考的考点之一,还是与高中物理有联系的知识之一,学生掌握好这部分知识,既能锻炼自己的思维,又能为今后学习高中物理的安培定则打下基础,所以这部分知识具有承上启下的作用。但是部分学生在学习电流的磁场时,特别是对通电螺线管的磁场应用不够熟练,导致该得的分遗憾地失去。一、学生常出现的错误及成因学生是否掌握所学的知识,就看他能否学以致用,常用三种题型来考查学生对这部分知识的掌握情况。
Current magnetic field is an important knowledge of junior high school physics, but also one of the test centers in the test, or high school physics associated with one of the knowledge, students master this part of the knowledge, both to exercise their own thinking, but also for the future study of high school Physical Ampere’s rules lay the foundation, so this part of the knowledge has a bearing on the role. However, some students are inexperienced in learning the magnetic field of the current, especially the magnetic field applied to the solenoid, resulting in the regrettable loss of that fraction. First, the students often appear errors and causes Students grasp the knowledge they have learned, to see if he can apply what they learn, commonly used three kinds of questions to examine the students grasp of this part of the knowledge.
