Heating characteristics of magnetic wood by induction heating

The purpose of this article is to examine the possibility of using magnetic wood as a heating board. This article covers top and side surfaces of heating characteristics for three types of magnetic wood (impregnated, powder and coating types) when using three different excitation coil types (solenoid, meander and spiral coil). Our results showed that the coating type magnetic wood had the highest top surface temperature when using a spiral excitation coil. In this case the top surface temperature rose 60/spl deg/C and good net heat. The temperature difference was 15/spl deg/C. The heating board we propose can be used in floor heating and for medical equipment that require a safe, warm and smooth surface.
