Maxwell Equations, Inductances, Magnetodynamics

This lecture covers the derivation of Maxwell's equations from the induction law, the concept of self- and mutual inductance to describe magnetic coupling between coils, and the calculation of inductances from real solenoids. It also explains the local form of the induction law, the significance of Maxwell's equations, and the introduction of inductance to quantify magnetic coupling. Practical examples include the calculation of self-inductance and mutual inductance between coils. The lecture concludes with a summary of induced currents, potential differences, self-inductance, and mutual inductance in solenoids.
