Abstract
Abstract This paper is concerned with a deep study of the magnetic field intensity distribution and the induced eddy currents in a core ( the work piece ) of a linear induction furnace . Numerical technique is considered in this study based on a general - purpose finite element package " ANSYS 5.4 " . The magnitude and direction of the current density of the induced eddy current in each point inside and at the external surfaces of the core of the induction furnace are well analyzed and determined . The effect of a wide range of frequencies on the magnetic field intensity distribution through the core are investigated and presented . a core Magnetic and non - magnetic isotropic linear materials are considered for furnaces with rotational symmetry . The achieved results show a good agreement and accuracy with respect to the previous work in this field . Therefore , the package represents an efficient tool to study the effect of furnace geometry , voltage , and frequency of the power supply on the core of the furnace .
