Magnetic Flux - Comparison With Electric Flux

Comparison With Electric Flux

By way of contrast, Gauss's law for electric fields, another of Maxwell's equations, is

where

E is the electric field,
S is any closed surface,
Q is the total electric charge inside the surface S,
ε0 is the electric constant (a universal constant, also called the "permittivity of free space").

Note that the flux of E through a closed surface is not always zero; this indicates the presence of "electric monopoles", that is, free positive or negative charges.

Famous quotes containing the words comparison, electric and/or flux:

    “It is very important not to become hard. The artist must always have one skin too few in comparison to other people, so you feel the slightest wind.”
    —Shusha Guppy (b. 1938)

    “Persons grouped around a fire or candle for warmth or light are less able to pursue independent thoughts, or even tasks, than people supplied with electric light. In the same way, the social and educational patterns latent in automation are those of self- employment and artistic autonomy.”
    —Marshall McLuhan (1911–1980)

    “Sense is a line, the mind is a circle. Sense is like a line which is the flux of a point running out from itself, but intellect like a circle that keeps within itself.”
    —Ralph J. Cudworth (1617–1688)
