| 摘 要： | 利用滑块带动金属杆切割亥姆霍兹线圈中心区域匀强磁场的磁感应线,可以产生感应电动势.通过实验可以验证感应电动势大小与金属杆运动速度、长度以及磁感应强度之间的关系,也可以验证感应电动势大小和磁通量变化率成正比.

| Abstract: | Using the slider to drive a metal bar to cut perpendicularly the uniform magnetic field in the center of a Helmholtz coil,induction electromotive force could be produced.Through this experiment the relation between the induction electromotive force and the length and velocity of the metal bar,the magnetic induction is verified.In addition,the proportional relation between the induction electromotive force and the changing rate of the magnetic flux could be verified too. |
