Electric flux density
Therefore, the electric flux density in this example is 2 x 10⁻⁸ C/m². In summary, electric flux density is a crucial concept in electromagnetism that helps us understand the behavior of electric fields. It is defined as the amount of electric flux per unit area and can be calculated using the formula D = ε * E, where D represents the ...Jul 23, 2023 · Electric Flux Density Question 5: A sphere of radius 10 cm has volume charge density \(\rho_v=\frac{r^3}{100}\) C/m 3. If it is required to make electric flux density D̅ = 0, for r > 10 cm, then the value of point charge that must be placed at the center of the sphere is _____ nC. The electric flux density is defined as $$\mathbf{D} = \epsilon_0 \mathbf{E} + \mathbf{P}$$ where P is the polarization vector of the material. As I understand it, the net electric field includes the polarization component, and we define D in such a way that it is independent of the material or the bound charge.

Electric flux is a defined quantity that is proportional to the no. of field lines passing through a given area element for a given electric field. It is not proportional to the relative density of field lines, which would supply information regarding the strength of the field at that point. Electric flux, it seems to me, does not supply us ...Polarization density.

A cylindrical Gaussian surface is commonly used to calculate the electric charge of an infinitely long, straight, 'ideal' wire. A Gaussian surface is a closed surface in three-dimensional space through which the flux of a vector field is calculated; usually the gravitational field, electric field, or magnetic field.
