WebTeaching Notes. When an electric current passes through a material, the material warms up. The open coil of wire will be warm to the touch. Blowing on the wire will reduce its temperature and the lamp will glow brighter. Try using an electronics freezer spray to reduce the temperature of the coil even more and the lamp will glow brighter still. WebWhen an object is placed in this field, two heating effects occur: Hysteresis losses – these occur only in magnetic materials such as iron, nickel, cobalt, etc., due to the friction between the molecules when the material is being continuously magnetized in different directions.
