落磁法演示楞次定律实验中磁环运动规律的探究

Investigation on the Magnetic Loop Motion Patterns in Lenz's Law Plummeting Experiment

在落磁法演示楞次定律实验的基础上,对磁环的运动规律从理论推导到实验验证做了初步的探究。介绍在磁环下落速度与时间以及下落速度与电阻率的关系。

In the experimental demonstration of Lenz＇s law, we set the magnetic loop in plummet phase to explore and prove the motion patterns from theory to practical experience. The two main achieve- ments of this study are about the relationship between the drop speed of magnetic loop and the time, and the relationship between drop velocity and electrical resistivity.
