ABSTRACT
THE MAIN PURPOSE OF THIS DISSERTATION IS TO ANALYZE ELECTROMAGNET- IC FIELD PROBLEMS BY USING FINITE ELEMENT METHOD. A GOVERNING EQUATION OF ELECTROMAGNETIC FIELD PROBLEMS IS DERIVED FROM MAXWELL'S EQUATIONS. FURTHER MORE, A LARGE COEFFICIENT MATRIX IS DERIVED FROM APPLYING FINITE ELEMENT METHOD IN ORDER TO GET THE VECTOR MAGNETIC POTENTIAL. IN ORDER TO ADEQUATELY UNDERSTAND THE FINITE ELEMENT METHOD, A COMMERCIAL SOFTWARE ANSOFT IS EMPLOYED. SOLUTION TECHNIQUES AND PROCEDURES ARE DESCRIBED. ANALYTIC SUBJECT IS TAKEN FROM THE ELECTROMA- GNET OF MAGNETIC LEVITATION SYSTEM TO ANALYZE THE
CHARACTERISTIC OF ELECTROMAGNETIC FIELD BY APPLYING DIFFERENT CONDITIONS.
Keywords : FINITE ELEMENT METHOD, GOVERNING EQUATION, ELECTROMAG-NET, MAGNETIC MATERIAL Table of Contents
