It is proposed a natural and consistent division of the momentum ofelectromagnetic waves in linear, non-dispersive and non-absorptive dielectricand magnetic media into material and electromagnetic parts. The material partis calculated using directly the Lorentz force law and the electromagneticmomentum density has the same form than in vacuum, without an explicitdependence on the properties of the media. The consistency of the treatment isverified through the obtention of a correct momentum balance equation in manyexamples and showing the compatibility of the division with the Einstein'stheory of relativity by the use of a gedanken experiment. An experimentalprediction for the radiation pressure on mirrors immersed in linear dielectricand magnetic media is also made.
