The objective for this course is three fold.
(1) To provide the students with a strong background in the
phenomena of electricity and magnetism at an intermediate
level.
(2) To introduce the mathematical techniques for setting up
and solving problems of electrical and magnetic field, DC
and AC electrical circuits, electromagnetic waves.
(3) To provide the students knowledge about close
connection between electrical and magnetic phenomena.
(1) Increase students knowledge and understanding of
electrical and magnetic phenomena in macroscopic and
microscopic level
(2) Increase students mathematical sophistication and ability to
solve problems in electricity and magnetism
(3) Strengthen students theoretical knowledge of Electricity
& Magnetism course by learning how to use experimental
equipment and how to investigate electrical and magnetic
phenomena
(4) Sharpen students experimental skills of independent
work making measurements, learn to use basic experimental
equipment
(5) Increase students skills to plan and carry out physical
experiments, analyze the results, estimate results error,
formulate conclusions.
The course “Electricity and magnetism” is developed for
electronics undergraduate students and is composed of two
parts – lectures and laboratory works. During lectures the
electrical and magnetic phenomena have been discussed and
analyzed – static electricity, electric current, magnetism,
electromagnetic induction, electromagnetic waves.
Mathematics is used for detailed description of physical
processes and laws. Laboratory works are foreseen to
develop experimental skills, to obtain, process and analyze
the results.
