We offer a new method that gives better understanding of the electromagnetic balance equations. This method is based on the idea that the macroscopic Maxwell equations, from which the balance equation is deduced, and the constitutive relations are sufficient for the derivation of the force density....
Forum: Advanced Physics Homework Help L Why is the electric force the negative of the position derivative of EPE? My interpretation of this equation is "how much does the electrical potential energy changes when I move the particle a little bit"? Suppose that I have some arrangement of charg...
The electric flux for the surface of the cube is given by Equation (12–20). The evaluation of the integral is simple if we execute the integration piecemeal. At every point on the cube face labeled A1, for example, E is constant and is in the same direction as dS, that is, θ =...
The interfacial electron transfer led to the generation of an electric field pointing from g-C3N4to MS2. The increased number of transferred electrons induced a stronger electric field. The strength of the electric field was calculated using equationE=P/(εSd).P,ε,andSweredipole moment,dielectri...
Equation (1) indicates that the electric wind is generated in the non-neutral region where \(n_{\mathrm{i}} \ne n_{\mathrm{e}}\). In the case of a cathode-directed (positive) streamer (that is a plasma bullet or pulsed plasma streamer) propagation, the electric wind is induced as...
Coulomb force, attraction or repulsion of particles or objects because of their electric charge. One of the basic physical forces, the electric force is named for a French physicist, Charles-Augustin de Coulomb, who in 1785 published the results of an ex
