为了更好的演示电磁相互转换现象,设计了一种新型单极转轮驱动与脉冲发电演示仪。该实验装置的工作过程分为转轮驱动和脉冲发电两个部分,能够同时演示电生磁和磁生电两个物理过程。同时,通过引导学生分析转轮驱动力来源、测量发电的电流波形以及计算装置能量利用率,能够加深他们对这两个物理过程的认识和理解。
Aiming at better demonstration of electromagnetic conversion phenomenon, new unipolar wheels drive and pulse electricity generation demonstrator is designed. The main work process of the experiment instru- ment is composed of two parts, wheel drive and pulse electricity generation. The system is able to demonstrate both electricity-generation-magnetism phenomenon and magnetism-generation-electricity phenomenon at the same time. By guiding students to analyze the sources of driving force, measure the current waveform and calcu- latethe energy efficiency of devices, their knowledge and understanding of these two physical processes can be deeply strengthened.
