WebSection 4.2 defines electric flux and electric flux density, and obtains the constant of proportionality between electric flux leaving and charge enclosed by a Gaussian surface. f~\CsM],`5/lH\2}J~hMV-tg4,Tw+{M^L.i( }Xu2dB."5\CHtcOt %|Tru+vO7:` dv \[\overrightarrow{D}=2.39\times10^{-7} (\overrightarrow{a_x}+3\overrightarrow{a_z})\hspace{0.5cm}C/m^2\], \[\overrightarrow{D}=\frac{\rho_s}{2}\frac{(x-5)\overrightarrow{a_x}}{(x-5)}\hspace{0.5cm}C/m^2\] If the photon photon flux density (fluence rate) i is a flat plate iwth area vector A that lies in a region of uniform electric field E. Rank the surfaces in order of the electric flux through them, from most positive to most negative. Magnetic flux lines are not always closed loops, just like electric flux lines. The $\vec D$ field certainly does suffer from a lack of a universally-accepted name (though the problem is less bad than in magnetism), but a better name is the one used in Wikipedia, "electric displacement field". The electric field has flux density, as opposed to force or change in electric potential. The density of these lines corresponds to the electric field strength, which could also be called the electric flux density: the number of "lines" per unit area. Electric Flux Density. The differential area of a vector is a quantity that is perpendicular to the electric field and is related to the magnitude and direction of the electric field. What is magnetic flux symbol?
