Electricity: curvilinear coordinates – conservative vector fields and their potential functions –Gauss’ theorem, Stokes’ theorem – physical applications in electrostatics – electrostatic po-tential and field due to discrete and continuous charge distributions – dipole and quadrupole moments – energy density in an electric field – dielectric polarization – conductors and capaci-tors – electric displacement vector – dielectric susceptibility.

Magnetism: Biot–Savart’s law and Ampere’s law in magnetostatics – magnetic induction due to configurations of current-carrying conductors – magnetization and surface currents – energy density in a magnetic field – magnetic permeability and susceptibility – force on a charged particle in electric and magnetic fields – electromotive force, Faraday’s law of electromagnetic induction – self and mutual inductance, displacement current.

Maxwell's equations – charge and energy – Poynting's theorem – momentum – Maxwell's stress tensor – conservation of momentum – angular momentum.
