Analysis and Application of Maxwell's Equation for Induction Heating

Abstract

This article involves the development of the Maxwell equations considering a induction heating system. It is analyzed by computer program "Ansys Maxwell," to observe the development of the magnetic field. The system is composed of an induction heating machine where it will be generating a 30(amp) of current to a coil of copper. The induced system is a cylinder of graphite. It was observed by the mentioned program and the behavior of the electromagnetic field. This shows that within the area of the cylinder if the phase angle is maintained at about 90 degrees, the magnetic flux lines generated by the coil maintain symmetry and a magnetic field increasing the current density at 2.4365x10 ^ 3 ª / m ^ 2. We know that if the current density also increases its temperature increases thereby bringing the internal area of the cylinder to very high temperatures.
