A godet for heating an advancing yarn including a rotatably mounted godet casing of magnetically conductive material, a stationary primary winding, and a power supply for powering the primary winding at least about 300 Hz. The godet casing is formed of iron and acts as both the secondary winding and core for the primary winding. Accordingly, the godet casing does not need a separate and defined secondary winding, nor does the godet casing include a copper insert or copper coating on the interior of the casing.
