Learning Outcomes
Following course completion, the students will be capable of comprehend and get familiar with the physical quantities, properties and methods of the electrostatic field, the steady state current flow field, the magnetostatic field as well as the behavior of materials in their presence, based on the macroscopic model of classical electromagnetism.
More specifically, the students will acquire the following skills:
- To understand the physical meaning of various physical quantities and concepts in various practical and applied problems of electrostatic and magnetostatic fields, the steady state current flow fields and describe the form of fields, charges and currents in respective systems.
- To perform simple calculations of the electrostatic and magnetostatic fields in simple, model components consisting of conductors and dielectrics, thus approximating more complex problems of current technological practice.
- To perform energy and power calculations in simple structures and components under the influence of electrostatic and magnetostatic fields.
- To use specialized electromagnetic analysis software for static fields to model complex devices and components.
General Competences
- Apply knowledge in practice
- Retrieve, analyse and synthesise data and information, with the use of necessary technologies
- Adapt to new situations
- Work autonomously
- Work in an interdisciplinary team
- Advance free, creative and causative thinking
