磁通量是重要概念之一,贯穿了整个电磁学始终,是高考经常考的内容,也是学生最容易弄错的概念之一.笔者从以下几方面开展教学,取得了良好效果.一、磁通量概念1.磁通量概念的定义和物理意义高中物理第二册(必修加选修)对磁通量定义如下:设在匀强磁场中有一个与磁场垂直的平面,磁场的磁感应强度为
Magnetic flux is one of the important concepts. It runs through the entire electromagnetics, is the content of the college entrance examination, and is also one of the most easily misunderstood concepts. The author has carried out teaching from the following aspects and achieved good results. First, the magnetic flux concept 1 The definition and physical meaning of the concept of magnetic flux High School Physics Book 2 (compulsory plus optional) defines the magnetic flux as follows: In a uniform magnetic field, there is a plane perpendicular to the magnetic field, and the magnetic field strength of the magnetic field is
