王铠泽, 陶小平 . 小磁体在金属管中下落的阻尼运动研究[J]. 大学物理, 2021 , 40(12) : 52 . DOI: 10.16854 / j.cnki.1000-0712.210140
The paper quantitatively studies the motion of the small magnet falling on the metal
tube，gives the relevant theoretical formulas，and designs experiments that measure physical
parameters such as the falling speed of the small magnet，the magnetic moment of the small magnet
and the resistivity of the metal tube.
Key words： permanent magnet; magnetic moment; vortex; damped motion
