With the use of a highly symmetrical model, the heating of a spherical particulate by a predominantly radio-frequency electric field and by a predominantly rf magnetic field is solved exactly using the Maxwell equations. It is found that, in general, heating by the rf magnetic field is dominant whenever δa, where λ is the free space wavelength of the rf field. The analysis may form a theoretical basis in the heating phenomenology of particulates.
