### Description

Version: 2.0 start 01 February 2020

#### Short description

Students acquire the physical and technical basics of electric and magnetic fields, and the coupling between these and wave theory. They learn about and apply Maxwell's equations. Using selected examples from these fields, they learn to adopt the state-of-the-art technical thinking of an engineer.

#### Module coordinator

Ralf Markendorf (mklf)

#### Learning objectives (competencies)

 Objectives Competences Taxonomy levels Students have understood the fundamental relationships of physics in the form of the fundamental laws, conservation laws and physical concepts and can apply them to concrete situations. F, M K2, K3 They are able to gain new knowledge through physical experimentation by means of observation, recognition (retrieval) of physical relationships, acquisition of data and their numerical evaluation and interpretation. F, M K2, K3 They can model physical situations, identify performance and validity limits of the model, further develop and refine models and obtain (qualitative and) quantitative results from the models. F, M K2, K3 Students learn about and can apply the inductively influenced physical way of thinking and working as part of the modern way of thinking and working of the engineer. This includes such important methods as experimenting, modelling or idealising and analogous thinking. They are able to check the correctness of results from experiments and models by rough calculations, borderline case considerations and evaluation of their plausibility by comparison with empirical values from technology or everyday life. F, M K2, K3
