Electric flux density
The quantity o E is called the electric displacement flux density and, [from (1)], has the units of coulomb/meter 2. Out of any region containing net charge, there must be a net displacement flux. The following example illustrates the mechanics of carrying out the volume and surface integrations. Figure 1.3.1 General surface S enclosing volume V.k = 1 4πϵo k = 1 4 π ϵ o. Therefore, Coulomb's law for two point charges in free space is given by Eq. 1. → F = Q1Q2 4πϵoR2 (1) F → = Q 1 Q 2 4 π ϵ o R 2 ( 1) Since Coulomb's law defines force, it has units of N (newtons). The permittivity of free space is 8.85418782×10 -12 and has units of C2 / Nm2 or F / m.Simple answer: because the electrostatic electric field owing to a point charge fulfils an inverse square law, or, equivalently, the electric potential ϕ ϕ from a point charge varies as r−1 r − 1. If the potential variation were some function other than 1/r 1 / r, the statement wouldn't be true. See for example my answer here, where I ...

電束密度（でんそくみつど、英語: electric flux density ）は、電荷の存在によって生じるベクトル場である。 電気変位（ electric displacement ）とも呼ばれる。 国際単位系（SI）における単位はクーロン毎平方メートル（記号: C m −2 ）が用いられる。 電場の強度は電荷に力を及ぼす場であり、電束密度 ...A slab of dielectric material has a relative dielectric constant of 3.8 and contains a uniform electric flux density of 8nC/m^2. If the material is lossless; find (a) E, which is the amplitude of the electric field. (b) The polarization P, and (c) The average number of dipoles per cubic meter (n) if the average dipole moment is p=10^-29CmA flux density in electric field, as opposed to a force or change in potential, is what describes an electric field. Magnetic Flux Density Unit It is derived from the unit magnetic flux density, which is defined as volt a second per square meter.Flux, Gauss' law. Flux. Problem: A disk with radius r = 0.10 m is oriented with its normal unit vector n at an angle of 30 o to a uniform electric field E with magnitude 2.0*10 3 N/C. (a) What is the electric flux through the disk? (b) What is the flux through the disk if it is turned so that its normal is perpendicular to E?

3. The electric flux, d Φ Φ through an area d S S is defined by. dΦ =E . dS . d Φ = E →. d S →. This is the same equation that gives the volume of a fluid flowing per second through an area dS d S → if the fluid's velocity at that point is E E →. That's how we get the name "flux".Magnetic Flux Density. The grouping of H and M in Faraday's law and the flux continuity law makes it natural to define a new variable, the magnetic flux density B. This quantity plays a role that is analogous to that of the electric displacement flux density D defined by (6.2.14). Because there are no macroscopic quantities of monopoles of ...
