# Module F: Applied Electromagnetics

## Subject description

Recapitulation of electromagnetic laws and relations.

Electric field. Electric force (particle in electric field, particle accelerator, cathode ray tube, powder coating, electrophotography, powder electric filtering, electrophoresis, Maxwell forces, electric lenses). Electrostatic shielding (influence, Faraday cage, wire grid, electrostatic guard).

Insulator. Calculation of capacity. Breakdown (atmospheric (dis)charging, ionization, lightening, lightening conduction, corona).

Current field. Calculation of resistance (fuses, grounding resistances, cathodic protection).

Magnetic field. Magnetic force (particle in magnetic field, mass spectrometer, cathode tube, Hall sensor, Maxwell forces, relay, electromagnet). Properties of magnetic materials. Magnetic circuits. Permanent electromagnet. Magnetic recording. Magnetic shielding.

Dynamic field.  Calculation of coil induction. Hysteresis and eddy current losses. Skin effect. Electromagnetic shielding. Electromagnetic field restrictions in living environment (mobile telephony base stations).

Fundamentals of electromagnetic waves.

## Objectives and competences

To acquire electromagnetic theory and numerical methods through practical examples and applications.

To use tools for numerical calculations of electromagnetic problems.

## Teaching and learning methods

Lectures and laboratory work.

## Expected study results

After successful completion of the course, students should be able to:

– evaluate effects of electric, current, magnetic and electromagnetic field,

– define material dependent geometric properties of selected electromagnetic structures: resistance, capacitance, inductance,

– select and explain suitable models for field or circuits evaluation,

– develop or use a program code for field determination or circuit solving,

– use suitable software package for numerical simulations of electromagnetic structures,

– present the result of numerical computation of practical examples.
