We present a momentum balance equation derived directly from Maxwell's equations. This equation contains a force density, which we call Maxwell's force density, which generalizes the Lorentz force density, now including total fields rather than only external fields, and arbitrary charge and current distributions. As a test for this balance equation we derive for gases the electrostatic and magnetostatic Helmholtz force densities. This deduction will be useful for advanced undergraduates and graduate students, as well as for specialists interested in the conceptual aspects of electromagnetism.

Mpd Thrusters

An MPD thruster formulation involving coupled aerothermodynamic-electromagnetic equations and including viscous effects is developed and solved. The electromagnetic force density distribution in the thruster interior is studied. Axial force densities are found to be largest on the cathode longitudinal surface. Very large force densities are found at the cathode upstream end and this is attributed to large values of the Hall parameter. Over the rest of the cathode longitudinal surface, axial force densities increase with increasing inlet velocities and mass densities and larger plasma viscosities. Equivalent increases in inlet velocity and mass density produce effects of different magnitudes.

Conductive Properties

We discuss the use of tension density for analyzing the electronic structure of a molecular system in a nonequilibrium steady state under the existence of electric current. By using the Rigged QED quantities defined at each point in space, such as tension density, local electric conductive properties are investigated. In particular, by computing benzenedithiol, it is numerically shown that the tension density serves as counter force to the Lorentz force density.
