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.
