Lecture
This lecture covers the concept of magnetic dipole moment from a current loop, torque, force, and energy in a magnetic field. It explains the mechanical motion due to torque and how it is utilized in devices like motors and galvanometers. The lecture also delves into the magnetic field originating from a dipole, the field lines of a solenoid and a permanent magnet, and the magnetic field induced by a moving charge. Furthermore, it discusses the vector potential of a magnetic field and its analysis using the Poisson equation. The presentation concludes with a summary of Maxwell's equations for magnetostatics and the relationship between current density, magnetic field, and the vector potential.
