摘要: 对抗磁性材料和顺磁性材料在强磁场中的弱磁力进行测量.利用设计的实验装置,成功测得抗磁性石墨片和顺磁性材料铝片在永磁铁阵列表面受到的弱磁力.研究证明弱磁力的大小与磁场及磁场梯度乘积成正比.

关键词: 抗磁性, 顺磁性, 弱磁力, 实验测量

Abstract: The weak magnetic forces of diamagnetic graphite and paramagnetic aluminum foils have been successfully measured, the relations between the weak magnetic force and magnetic field as well as magnetic field gradient are also obtained. It is shown that the magnetic force is proportional to the product of magnetic field and its gradient

Key words: diamagnetic, paramagnetic, weak magnetic, experimental measurement
