Motional EMF
Derive the EMF for conductors moving in magnetic fields. Analyze sliding-rail and rotating-coil generators.
Inductance and RL Circuits
Calculate self-inductance and mutual inductance. Solve RL transient problems using exponential growth and decay.
Energy in Magnetic Fields
Compute energy stored in inductors and the magnetic energy density. Compare with electric field energy storage.
Maxwell s Equations and Electromagnetic Waves
Complete Ampere s law with displacement current. See how the four Maxwell equations predict electromagnetic waves at speed $c=1/\sqrt{\mu_0\varepsilon_0}$.
