摘　　要：基于对导体在磁场中运动而导致的磁悬浮力、磁牵引力等磁悬浮现象规律性的进一步认识,研究了电磁感应与磁悬浮实验。具体研究了磁悬浮力、磁牵引力与铝盘转速的关系,磁铁与铝盘间纵向距离变化对磁悬浮力、磁牵引力的影响,磁铁与铝盘间横向位置变化对磁悬浮力、磁牵引力的影响,铝盘转速与轴承转速之间的关系。结果表明,磁悬浮力、磁牵引力、轴承转速与铝盘转速满足线性关系;随着磁铁与铝盘间纵向距离的增大,磁悬浮力、磁牵引力减小;随着磁铁与铝盘间横向位置的改变,磁悬浮力、磁牵引力先增大,后减小,存在最大值。The experiment of electromagnetic induction and magnetic suspension was studied based on the further understanding of regularity of magnetic suspension phenomenon such as the magnetic levitation force and magnetic tractive force caused by the conductor motion in the magnetic field.The relationship between magnetic levitation force,magnetic tractive force and rotating speed of aluminum disk was studied,and the influence of the longitudinal distance between magnet and aluminum disk on magnetic levitation force and magnetic tractive force was discussed,as well as the influence of lateral distance between magnet and aluminum disk on magnetic levitation force and magnetic tractive force and the relationship between the rotating speed of aluminum disk and the rotating speed of bearing are studied concretely.The results showed that the magnetic levitation force and magnetic tractive force was linearly related to the rotating speed of aluminum disk.With the increase of the longitudinal distance between the magnet and the aluminum disk,the magnetic levitation force and magnetic tractive force decrease and with the increase of the lateral distance between the magnet and the aluminum disk,the magnetic levitation force and magnetic tractive force increase first,then decrease,and the maximum value exists.
