Lecture
This lecture covers the concept of multipole expansion in Electrodynamics, discussing topics such as Maxwell Equations, EM Potentials, Lorenz Gauge, Retarded electromagnetic potentials, and Magnetization. It also explains the terms monopole, dipole, traceless tensor, and symmetric tensor, providing insights into the names quadrupole and octopole. The instructor emphasizes the importance of understanding the magnetic moment, slow sources, and the characteristics of radiation from charged particles.
