摘　　要：根据电磁学的基本原理,永磁体或载流线圈在外磁场中会受到磁力的作用,当磁力完全克服重力时便达到磁悬浮状态。基于磁悬浮的基本原理,本文设计制作了一种新型的磁悬浮实验教学装置,利用一套装置有机地将磁场、电流与力结合起来,实现了直流和交流磁悬浮以及内磁悬浮和外磁悬浮。利用该装置,可以开展基于磁悬浮的磁力秤和磁力电流计等实验内容,定量地探究磁场、电流和力之间的关系。该实验教学装置结构简单,成本低,实验内容丰富,可以很好地锻炼学生的动手能力和创新能力,非常适合在大学物理实验教学中进行推广。According to the basic principle of electromagnetism,the permanent magnet or current-carrying coil will be affected by the magnetic force in the external magnetic field.When the magnetic force completely overcomes the gravity,it will reach the state of magnetic levitation.Based on the basic principle of magnetic levitation,we have designed a new type of magnetic levitation device for experimental teaching,which employs a set of devices to organically combine magnetic field,current and force to realize DC and AC magnetic levitation,as well as inner and outer magnetic levitation.Using this device,experiments such as magnetic scales and magnetic ammeter based on magnetic levitation can be carried out to quantitatively explore the relationship between magnetic field,current and force.The experimental teaching device has a simple structure,low cost,and rich content,which can effectively train studentshandson and innovative abilities,making it very suitable for promotion in college physics teaching experiments.
