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 with, comparison, electric and/or flux:

    “In everyone’s youthful dreams, philosophy is still vaguely but inseparably, and with singular truth, associated with the East, nor do after years discover its local habitation in the Western world. In comparison with the philosophers of the East, we may say that modern Europe has yet given birth to none.”
    —Henry David Thoreau (1817–1862)

    “The more I see of democracy the more I dislike it. It just brings everything down to the mere vulgar level of wages and prices, electric light and water closets, and nothing else.”
    —D.H. (David Herbert)

    “Beauty is our weapon against nature; by it we make objects, giving them limit, symmetry, proportion. Beauty halts and freezes the melting flux of nature.”
    —Camille Paglia (b. 1947)
