一、制作背景磁场是一种看不见、摸不着的特殊物质,在中学物理教学中,学生对磁感线的分布很难具体想象出来。因此,这部分内容的学习就成为学生学习中难以跨越的障碍。然而,作为磁场部分的基础知识,对磁感线分布的准确掌握,直接影响学生对磁场相关问题的学习和理解。那么在实际教学中,如何才能让学生直观感受磁场的分布,更好地理解及掌握磁感线的走
First, the production background Magnetic field is an invisible, inaccessible special material, physics teaching in secondary schools, the distribution of magnetic induction line is difficult to specifically imagine. Therefore, this part of the content of learning has become an obstacle in student learning is difficult to cross. However, as the basic knowledge of the magnetic field, the accurate mastery of the magnetic line distribution directly affects students’ learning and understanding of magnetic field-related problems. So in the actual teaching, how to let students intuitively feel the magnetic field distribution, to better understand and grasp the magnetic line
