Flux refers how much a vector field intersects through a given area. The word flux is Latin for flow, so it represents how much a field flows through a given area.
Generally, the symbol of flux is capital Phi (). Flux can refer to:
Definition
Formula - 1
Flux on an Area
\Phi_Q = \vec{F}_{Q}\cdot\vec{A}
##### Formula - 2
>[!formula] Flux on a Surface
>
>$$
>\Phi_{Q} = \oint \vec{F}_{Q} \cdot \text{d}\vec{A}
>$$
##### Terms
* $\Phi_{Q}$ = Flux, dependant on the physical quantity
* $\Phi_{E}$ = [Electric Flux](Electric%20Flux.md)
* $\Phi_{B}$ = [Magnetic Flux](Magnetic%20Flux.md)
* $\vec{F}_{Q}$ = A [vector field](vector%20field), representing a physical quantity ($Q$). It can be anything, for example for magnetic flux, it is the [Magnetic Field](Magnetic%20Field.md), while for electric flux it is the [Electric Field](Electric%20Field.md).
