Electricity and Magnetism Course developer Credit points Volume (number of academic contact-hours per semester) Assessment Course prerequisites Course group (required, compulsory choice or free choice Course objectives Results Janis Harja 4 (6 ECTS) 64 (32 – lectures, 32 – work in laboratory) Exam Mechanics required 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.
