If you’re looking to deepen your understanding of electromagnetism, the Coursera course ‘电磁学下——恒磁场与时变电磁场’ is an excellent choice. This course serves as the second part of the electromagnetism learning process, building on the foundational knowledge acquired in the first part. It covers a wide range of topics including constant magnetic fields, magnetic media, electromagnetic induction, alternating current, and electromagnetic waves.
The course is structured into six modules, each focusing on specific concepts:
1. **Basic Laws of Constant Magnetic Fields**: This module introduces the historical context of magnetic field research, essential definitions, and core principles such as the Biot-Savart Law and Ampère’s Circuital Law.
2. **Magnetic Force**: Here, students learn about Ampère’s force and Lorentz force, integrating high school knowledge into a university framework while exploring the motion of charged particles in magnetic fields.
3. **Magnetic Media**: This module discusses the magnetization of materials and the laws governing magnetic fields in the presence of magnetic media, drawing parallels with electric polarization.
4. **Electromagnetic Induction**: Students revisit familiar concepts from high school, enhancing their understanding of induced electromotive force and the principles of self-induction and mutual induction.
5. **Alternating Current and Circuit Analysis**: This module delves into AC circuits, requiring some mathematical background, and introduces the concepts of impedance and phase relationships.
6. **Electromagnetic Fields and Waves**: The final module covers Maxwell’s equations and the properties of electromagnetic waves, emphasizing the historical development of electromagnetic theory.
The course is designed to be flexible, allowing students to self-test and progress at their own pace. Each module includes exercises that reinforce understanding and provide opportunities for self-assessment.
Overall, ‘电磁学下——恒磁场与时变电磁场’ is a comprehensive course that not only builds on previous knowledge but also challenges students to engage deeply with the material. I highly recommend this course for anyone serious about mastering electromagnetism, whether you’re a student or a professional looking to refresh your knowledge. The theoretical rigor and structured approach make it a valuable resource in the field of physics.
