摘要
主要采用了在方向可调的匀强磁场中的矩形线圈受到磁场力的典型情境,教师辅助学生不断整理、分类和定量分析运用Excel运算的数据,然后结合比值定义法等物理科学方法进行比较和归纳,最终寻找到一种建立并定义磁感应强度这一物理概念的新角度.
Set in typicalexperiment conditions for a rectangular coil in a uniform magnetic field with adjustable directions subjected to magnetic force,students will be assisted by the teacher to process,classify and quantify the experiment data using Microsoft Excel,and then to compare and generalize the experimental results employing scientific methods in physics like the ratio definition method,etc.,thus leading to finding a new angle to building up the understanding of the concept of magnetic induction intensity.
