Learning outcomes

The subject "Electricity and Magnetism" is based on lectures, numerical ecercises and practical training in laboratory. Lectures consist of historical findings and they are evolved on the basis of recent physics. Electrical and magnetical phenomenon will presented as associated with electromagnetic field. The understanding of electrical a magnetical phenomenon and their physical context with chemistry, biology and mathematics is crucial competence in this education.
Knowledge Define the main ideas and conceptions of the subject, describe the main approaches of the studied topics, recall the theoretical knowledge for solution of model problems. Application of nontraditional methods of teaching, the use of ICT.
