MAGNETIC FIELD CALCULATION IN THE VICINITY OF THE MAGNETIC COILS USING FLUX 3D

Diplomsko delo zajema izračun magnetnega polja tuljav s pomočjo programa Cedrat FLUX 3D. Simulacijo in izračun smo izvajali v laboratoriju za aplikativno elektromagnetiko Fakultete za elektrotehniko, računalništvo in informatiko - FERI UM. Izračun smo izvajali s programom FLUX 3D, s katerim je možno izračunati in izrisati porazdelitev gostote magnetnega polja ter inducirane tokovne gostote v okolici tuljav. Z izračunom smo prikazali spreminjanje gostote magnetnega polja znotraj tuljav v različnih časovnih trenutkih ter kako se zmanjšuje gostota elektromagnetnega polja z oddaljevanjem od tuljave na različnih razdaljah in presekih. Prikazali smo tudi inducirano tokovno gostoto kot posledico časovno spremenljivega magnetnega polja za različne modele človeškega telesa, vstavljene znotraj tuljave.This dissertation presents magnetic field calculation around electric coils, using Cedrat FLUX 3D. The simulation and the calculation were performed in the Applied Electromagnetics Laboratory at the Faculty of Electrical Engineering and Computer Science, University of Maribor. The calculations were made with the use of the FLUX 3D program, which can be used for calculation and graphic presentation of the magnetic field and for induced current density distribution around the electric coils. The calculation was used to show changes in magnetic field density inside the electric coils at different time instants. The study reveals the decrease of the magnetic field density at different distances and coil cross-sections with increasing distance from the electric coil. Results also demonstrate the induced current densities in the different human body models placed inside the electric coil. These induced current densities are a consequence of the time-dependant magnetic field
