Lecture
This lecture covers the concepts of electrostatics and magnetostatics, focusing on the redistribution of charge density until equilibrium, the uniqueness of electric fields, and the relationship between charge density and electric field. It also discusses the independence of charge density on time, the definition of electrostatic and magnetostatic conditions, and the coupling of electric and magnetic fields. The lecture further explores charge conservation, the electric potential in static cases, and the calculation of electric fields in different scenarios.
