摘要：

Total electromagnetic force on a body can be predicted by replacing the magnetization and polarization with appropriate equivalent currents and charges. Still, the equivalence of total force does not imply that the integrated densities have physical meaning. Instead of defining local electromagnetic force by using equivalent currents and charges we begin its determination from basic material elements. An example case illustrates how the approach can be used to compute magnetic force densities.
