Ⅰ.电磁学的发展简史 1831年法拉第实验发现,变化的磁场会在导体中感生电流,这一发现为发电机、变压器的发展奠定了基础。 1853年凯尔文第一次详细分析了电容器经过电感回路产生振荡性放电的现象,求出该
Ⅰ. A Brief History of Electromagnetism Faraday’s experiment in 1831 found that the changing magnetic field induced current in the conductor. This finding laid the foundation for the development of generators and transformers. 1853 Kelvin first detailed analysis of the capacitor through the inductor loop oscillating discharge phenomenon, find the
