17 Maxwell Equations, Charles G. Torre
17 Maxwell Equations, Charles G. Torre
Foundations of Wave Phenomena
With our brief review of vector analysis out of the way, we can now discuss the Maxwell equations. We use the Gaussian system of electromagnetic units and let c denote the speed of light in vacuum. The Maxwell equations are differential equations for the electric field E(r, t), and the magnetic field B(r, t), which are defined by the force they exert on a test charge q at the point r at time t. This force is defined by the Lorentz force law.
String Fluid Cosmological Model With Magnetic Field In Bimetric Theory Of Gravitation, M. S. Borkar, N. P. Gaikwad
String Fluid Cosmological Model With Magnetic Field In Bimetric Theory Of Gravitation, M. S. Borkar, N. P. Gaikwad
Applications and Applied Mathematics: An International Journal (AAM)
In this paper, LRS Bianchi type I string fluid cosmological model with magnetic field in bimetric theory of gravitation is investigated by assuming barotropic equation of state for pressure and density and assuming the bulk viscosity to be inversely proportional to the scalar expansion. The source of energy momentum tensor is a bulk viscous fluid containing one dimensional string with electromagnetic field. The physical and geometrical properties of the model are discussed. The bulk viscosity affected the whole properties of the model.

Turkish Journal of Physics
Considering a spherically symmetric nonstatic cosmological flat model of the Robertson-Walker universe, the problem of perfect fluid distribution interacting with the gravitational field in the presence of a zero-rest-mass scalar field and electromagnetic field in Brans-Dicke (B-D) theory has been investigated. Exact solutions are obtained by using a general approach of solving the partial differential equations and it has been observed that the electromagnetic field cannot survive the cosmological flat model due to the action caused by the presence of the zero-rest-mass scalar field, and the isotropic pressure p turns out to be negative. The pressure and density are found …
