| 中文摘要: |
| 电磁学是电气专业的基础学科,电类学生必须深刻掌握,普通工科学生也要学习。目前电磁学的教材都是从知识点本身出发进行讲解,虽然严谨,却显得抽象,不利于初学者理解。本文通过流体的特点,来类比电磁学中重要概念和定律(基尔霍夫电压电流定律和位移电流)。通过将难以捉摸的“电”和“磁”具象化,拉进学生与知识点之间的距离,达到快速理解吸收的目的。 |
| 英文摘要: |
| Electromagnetics is the basic subject of electrical major. Electrical students must master it deeply, and ordinary engineering students should also learn it. At present, the teaching materials of electromagnetism are all explained from the knowledge point itself. Although they are rigorous, they appear abstract, which is not conducive to the understanding of beginners. By comparing with the characteristics of fluid, the important concepts and laws of electromagnetism (Kirchhoff"s law and displacement current) are explained. By concreting the invisible and untouchable electricity and magnetism, the distance between students and the knowledge point is shortened to achieve the purpose of rapid understanding and absorption. |
