Electric flux is a property of an electric field. It may be thought of as the number of forces that intersect a given area. Electric field lines are usually considered to start on positive electric charges and to end on negative charges. Field lines directed into a closed surface are consi...
The electron energy flux (averaged over a spatial resolution of 0.5deg) deposited in the ionosphere due to auroral electron beams as estimated from the intensity in the UVI Lyman-Birge-Hopfield-long filters is 15-30 ergs cm -2 s -1. Thus there is evidence that these electric field ...
The free charge portion produces the electric Field F and the electric flux density of εoF, while the bound charge portion produces polarization P. + and – denote the free positive and negative charges, respectively, and ⊞ and ⊟ denote the bound positive and negative charges, ...
