Materials with magnetic properties, regardless of ferro-magnetic, ortho-magnetic, or anti-magnetic, are heated in magnetic field of high frequency electromagnetic waves. The intensity of heating varies with composition of the materials. Among the iron oxides, hematite Fe2O3 is not heated significantly, but magnetite Fe2O4 is heated extensively. Among the titanium oxides, TiO exhibits greater microwave absorption than TiO2. As such, pure water exhibits smaller microwave absorption than water containing impurities such as various oxides. Selective heating appears in a mixture of magnetic and non-magnetic materials.
