The examinations during the course consist of three tasks with different scope and correspondingly different influence on the grade:

1. Simulation of two electrostatic arrangements. Exploitation of model symmetries. (20 %)

2. Simulation and optimisation of a magnetic arrangement with materials with linear and non-linear magnetisation characteristic. (20 %)

3. Automation of a simulation of a magnetic arrangement with Python and calculation of characteristics by parameter variation and output to a diagram. (60 %)
