This is a first module on electro/magnetostatics and electrodynamics in differential form with key applications.

Topics covered include:

  1. Mathematical Revision
  2. Electrostatics: equations for the E-field, potential, energy, basic boundary-value setups
  3. Electrostatics: dielectrics, displacement and free charge
  4. Magnetostatics: forces, equations for the B-field, vector potential, Biot-Savart, dipole field of current loops
  5. Magnetostatics: diamagnetism and paramagnetism, auxiliary field H, ferromagnetism
  6. Electrodynamics: Faraday's law, inductance and back emf, circuit applications, Maxwell-Ampere law, energy and Poynting's theorem
  7. Electromagnetic waves: wave equation, plane waves, polarization, waves in dielectrics, reflection at an interface, wave velocity/group velocity/dispersion
  8. Potentials and dipole radiation
