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:

    “He was a superior man. He did not value his bodily life in comparison with ideal things. He did not recognize unjust human laws, but resisted them as he was bid. For once we are lifted out of the trivialness and dust of politics into the region of truth and manhood.”
    —Henry David Thoreau (1817–1862)

    “It is comparison than makes people miserable.”
    —Chinese proverb.

    “That’s the down-town frieze,
    Principally the church steeple,
    A black line beside a white line;
    And the stack of the electric plant,
    A black line drawn on flat air.”
    —Wallace Stevens (1879–1955)

    “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)
