Webdivergence of E will be zero, so the charge density ρ=0 everywhere. Thus, the total enclosed charge in any volume is zero, and by the integral form of Gauss’ Law the total flux through the surface of that volume must be zero.

WebApr 1, 2024 · The only way this is possible is if the integrand is everywhere equal to zero. We conclude: (7.3.2) ∇ ⋅ B = 0. The differential (“point”) form of Gauss’ Law for Magnetic Fields (Equation 7.3.2) states that the flux per unit volume of the magnetic field is always zero. This is another way of saying that there is no point in space that ...
In physics and electromagnetism, Gauss's law, also known as Gauss's flux theorem, (or sometimes simply called Gauss's theorem) is a law relating the distribution of electric charge to the resulting electric field. In its integral form, it states that the flux of the electric field out of an arbitrary closed surface is … See more In words, Gauss's law states: The net electric flux through any hypothetical closed surface is equal to 1/ε0 times the net electric charge enclosed within that closed surface. The closed surface is also … See more Free, bound, and total charge The electric charge that arises in the simplest textbook situations would be classified as "free charge"—for example, the charge which is … See more In terms of fields of force Gauss's theorem can be interpreted in terms of the lines of force of the field as follows: The flux through a closed surface is dependent upon both the magnitude and direction of the … See more 1. ^ Duhem, Pierre (1891).
