We conclude that these forces are not exactly analogous, as usually thought. We present a device that is a proper analogy of the case of a dielectric slab inside a capacitor. Our analysis shows the significance of the electrostatic and magnetostatic pressures to the understanding of these effects and shows the conceptual differences between both cases. %K Polarizable Electric and Magnetic Media %K Electric and Magnetic Pressures %K Electromagnetic Force Densities %K Macroscopic Maxwell Equations %K Balance Equations of Electromagnetic Momentum %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=91517
