Lorentz force, moving charge in electromagnetic field. Torque and work of magnetic force. Magnetic dipole, magnetic material and magnetic field, magnetization, magnetic field strength, permeability, boundary conditions of magnetic field. Magnetomotive force, scalar magnetic potential, elements of magnetic circuits. 

Faraday induction law. Electromotive force voltage and electric field, Stokes’ theorem of electric field, motional and transformer electromotances. Magnetic flux linkage, self and mutual inductances, coils and coupled coils. Magnetic field energy, lifting force. Electromagnets. Displacement current. Maxwell’s equations. 

AC electric circuits. Transients. Sinusoidal steady-state electric circuits and analysis in complex domain: phasors, impedance and admittance, complex power, resonance, oscillators. Theorems. Transformer. Three-phase circuits. Rotating magnetic field. 

To acquire fundamental knowledge on magnetic field, induced field as well as AC electric circuits, three phase systems and transient circuit analysis. The acquired knowledge serves as a basis for further electrotechnical studies.

Lectures are used to teach students the basic theory of electrical engineering from the course Content and use additional practical examples to elaborate on it. In lectures also demonstration experiments are used together with computer animations. Some computer tools are presented that are used in computation and visualization of electric fields.

At the tutorials (exercises) the students elaborate further the problems by solving specific tasks / cases with analytical solutions.

Laboratory exercises include preparations where students get acquainted with work to be performed in a laboratory, homework, where students independently solve the pre-prepared case and additional literature studies and experimental work in the laboratory, where they prepare experiments according to the instructions and describe the experimental results
