Magnetostatics: Fields and Potentials

This lecture covers the creation of magnetic and electric fields by stationary currents and static charges, emphasizing analogies and differences between electrostatics and magnetostatics. It also explores Ampere's and Gauss's laws, field symmetries, and the absence of magnetic monopoles. The concepts of energy density, scalar and vector potentials, and dipoles in electric and magnetic fields are discussed, along with their interpretations and applications.
