On Data and Care in Migration ContextsAn important quantity associated with fields is the flux through a surface. The term is borrowed from fluid mechanics and appears as a measure of the amount of fluid flowing out through a surface.

On Data and Care in Migration ContextsWe suppose that the charges are contained in a bounded region and investigate the potential at a point outside that region. We take the origin within the charge distribution.

https://doi.org/10.1007/978-3-319-27167-5We have already seen how Laplace’s equation can be solved in spherical polar coordinates. The method used there is known as separation of variables and can be applied with other coordinates as well.

https://doi.org/10.1007/978-3-319-27167-5Electrostatic forces being derivable from a potential, one can associate potential energy with charges moving under electrostatic forces. Field theory, however, makes it possible to consider that this energy is associated with the field.

Management and Industrial EngineeringWe shall be interested in crystalline media, other than those belonging to the cubic type, in which the dielectric constant may not be considered as a scalar, but must be replaced by a tensor, i.e.,

The Nature and Relevance of Theories,Let us start by listing the Maxwell equations again, which admit (from Eqs. (.) and (.), respectively) the introduction of a vector potential . and a scalar potential . such that.

Analysis Related to Breeding Researches,We find the field from the Liénard-Wiechert potential, this time taking into account that . is no longer independent of time. This brings in some additional terms.
