Abstract
Za potrebe ovog završnog rada bilo je potrebno odrediti gubitke u kugli koja se nalazi u sinusno promjenjivom magnetskom polju. Gubitci su prvo dobiveni analitičkim proračunom, pri čemu su pretpostavljeni kvazistatički uvjeti. Problem je riješen preko vektorskog magnetskog potencijala. Dobiveni su izrazi za magnetsku indukciju, gustoću struje i omske gubitke nastale uslijed djelovanja vrtložnih struja. Potom je proveden i numerički proračun u programskom paketu Infolytica MagNet. Za numerički proračun korišten je 2D model, zbog osnosimetrične geometrije problema. Dobiveni su prikazi polja i struja u kugli. Dobiveni gubitci izraženi su numerički. Rezultati analitičkog i numeričkog proračuna su uspoređeni, te je zaključeno da je analitički proračun točan.
Abstract (english)
Purpose of this final work was to determine losses in the ball, which is located in the sinusoidal magnetic field. Losses were obtained analytically, assuming quasistatic conditions. The problem is solved using vector magnetic potential. Expressions were obtained for magnetic induction, current density and total ohmic losses due to eddy currents. After analytical calculation, losses were obtained by numerical calculation, which was carried out in the Infolytica MagNet program package. For the numerical calculation, 2D model was used, due to axisymmetric geometry of the problem. Total ohmic losses obtained are expressed numerically. MagNet also provided the display of magnetic induction and current density fields. Results of the analytical and numerical calculations were compared, and conclusion was that the analytical calculation is accurate.
