20.500.12556/DKUM-11776 ANALIZA HOMOGENOSTI MAGNETNEGA POLJA V VZORCU MERILCA LASTNOSTI MAGNETNE PLOČEVINE Z UPORABO PROGRAMA FLUX 3D ANALYSIS OF THE MAGNETIC FIELD HOMOGENEILY IN THE SAMPLE OF THE SQUARE ROTATIONAL SINGLE TESTER USING FLUX 3D. Diplomsko delo v osnovi zajema modeliranje merilca lastnosti magnetne pločevine s kvadratnim vzorcem s programskim paketom Flux 3D. Z njim smo želeli izvesti statični ter tranzientni izračun. Pri statičnem izračunu smo izvedli dve za nas zanimivi poziciji magnetenja vzorca, in sicer v vzdolžni ter diagonalni smeri. S tem izračunom smo hoteli videti spreminjanje gostote magnetnega polja v vzorcu in jarmu pri B= 1 T v sredini vzorca. Pri tranzientnem izračunu oziroma v rotacijskem magnetnem polju smo želeli določiti optimalno dolžino merilnih tuljavic na osnovi numerične analize B v vzorcu merilca magnetne pločevine za vrednosti B v sredini vzorca približno 1 T in 1,5 T. Poleg tega smo izvedli še primerjavo izmerjenih in izračunanih vrednosti B-ja. This dissertation presents modelling of the rotational single sheet tester with square sample using Cedrat FLUX 3D. The static and transient calculations were made. Static calculations were calculated for two interesting positions of the sample magnetization direction, which are the direction along the sample and the direction transverse the sample. With the calculation the analysis of the change of the magnetic field density in the yoke and in the sample at B=1T in the centre of the sample could be observed. The aim of the transient calculations was the definition of the optimal measuring coils length based on the numerical analysis of B in the sample placed in the rotational magnetic field for the values of B=1T and B=1.5T in the centre of the sample. The calculated and measured values of B were compared. magnetno polje metoda končnih elementov magnetne meritve Magnetic field Finite element method Magnetic measurements true true false [M.
