The course covers and expands material which is normally presented in the last years of high school but using higher mathematics. One of its basic goals is to introduce the students to the use of differential calculus and vector analysis to the study of the laws of electrostatics, magnetostatics and electromagnetism. Using integrals the student should be able to compute the electric field and potential of various distributions of charge which have some symmetry in their geometry or respectively the magnetic field of moving charges and currents. Various theorems and equations (e.g. Gauss, Biot-Savart, Ampere, Faraday, Maxwell’s equations) should be understood in their general form and not just in their simplified versions exposed in high school textbooks. Beyond that, one of the objectives of the course is the physical and mathematical study of more sophisticated topics of electricity and magnetism, such as the method of images, the electric dipole, the dielectrics, the magnetic materials, the scalar and vector potentials of electromagnetism, the energy/momentum conservation theorems and elements of electromagnetic waves.
