This paper deals with the numerical modeling of the electromagnetic field in transverse flux induction heating devices and with features of forces due to non-symmetrical position of the sheet to be heated within the inductor air-gap. The results of four field computation models are compared.
Three computation methods of the electromagnetic force acting on non-magnetic and magnetic sheets are used. The influence of the horizontal and vertical sheet positions in the inductor air-gap is analyzed. A particular variation of the electromagnetic force with the field frequency is emphasized for magnetic sheets.
