Energy in electromagnetic systems; Poynting vector

Electromagnetism: Lecture 4

Theoretical physicist Dr Andrew Mitchell presents an undergraduate lecture course on classical Electromagnetism / Electrodynamics at University College Dublin.

In this lecture, I discuss the energy stored in electromagnetic systems, and show that static electric and magnetic field configurations store energy. The work-energy theorem is derived for electrodynamic systems, which is a continuity equation for the local conservation of energy. The Poynting vector describes the energy flux density.

The textbook "Introduction to Electrodynamics" by Griffiths is recommended reading to accompany this course.
