ABSTRACT:
A heat apparatus for an electromagnetic induction heating system comprises a heat roller that comprises magnetic and conductive material. The heating apparatus also comprises a magnetic excitation coil that is positioned around a portion of the periphery of the heat roller. The magnetic excitation coil is configured to generate a magnetic field that extends to the heat roller, to generate an eddy current within the heat roller, and to generate Joule heat within the heat roller. The magnetic excitation coil is configured to generate a smaller magnetic field at the center area of the heat roller than at the side areas of the heat roller.
