法拉第电磁感应定律定量分析探究演示仪

Demonstrator for quantitative analysis of Faraday law of induction

针对传统的法拉第电磁感应定律演示装置只能进行定性或半定量分析的问题,设计了法拉第电磁感应定律定量分析探究演示仪,该实验装置不但能更好的演示法拉第电磁感应定律,而且还可完成定量分析和探究,演示效果好,定量分析精确度高,值得在中学物理教学中推广.

Traditional demonstrator of Faraday law of induction could provide qualitative and semi-quantitative analysis only, so a quantitative analysis demonstrator of Faraday law of induction was designed. By changing the rotate speed of electrical motor, the relation of the change rate of flux and the speed of the coil was explored. By changing the number of magnet, the relation of the change rate of flux and magnetic field strength was explored. By changing the taps of the coil, the change of the magnetic induction was explored when changing the number of coils.
