摘　　要：实验采用气垫导轨技术,测量了钕铁硼磁性材料一维相互作用引力与磁体间距之间的关系曲线,利用能量转化原理,通过动能的测量并利用Matelab软件进行曲线拟合,间接测量了钕铁硼磁体的磁相互作用位能与磁体间距之间的关系曲线。In this paper, we described the relational curve between NFB magnet one-dimensional interactional force and magnet spacing according to the results of measurements on the air track. We also draw the relational curve between the magnetic potential energy of NdFeB magnet and magnet spacing by using the theory of energy transforming and applying MATLAB in curve fitting.
