Course details

This course introduces the fundamental concepts of electromagnetics for Electrical and Electronics Engineering (EEE) students. It begins with a clear review of vector algebra and vector calculus, which are essential tools for understanding electromagnetic fields. Students learn how electric and magnetic fields are represented and analyzed in space. The course then covers electrostatics, focusing on electric charges, electric fields, and electric potential. Important laws such as Coulomb’s Law and Gauss’s Law are explained in a simple and step-by-step manner. Magnetostatics is introduced to help students understand magnetic fields produced by steady currents. The relationship between electricity and magnetism is discussed using practical examples. Time-varying fields are also covered to explain how changing electric and magnetic fields interact. Mathematical concepts are always linked to physical meaning for better understanding. By the end of the course, students gain a strong foundation needed for advanced subjects in power systems, electronics, and communication engineering.

Questions and Answers

Q: You're reviewing a failed EMC chamber test and googling "motor inverter electromagnetic field corrosion on copper busbar". The HV busbars show green corrosion after 200 hours at 85°C/85%RH with a 20 kHz switching field present. What degradation mechanism is actually driving this?

Q: Final day of homologation. You're searching "radiated emissions fail only at 150 kHz inverter". The vehicle fails CISPR 25 only at 150 kHz, 3% over the limit, and only under high load. What root cause best fits all symptoms?

Q: During a design review you're typing "how to reduce magnetic field coupling between parallel cables 50 A automotive". Two 50 A DC cables run 300 mm in parallel. Space is tight. What change gives the biggest reduction in magnetic field coupling?

Q: On-site pre-SAT you're googling "verify EMC fix before CISPR retest common mode choke". A common-mode choke was added to fix a 3% margin fail. What's the correct verification step before booking the chamber?
