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.
