- The definition of a flux is a flow of liquid from the body, or a constant movement or change.
- An example of flux is diarrhea.
- An example of flux is an ever changing list of the responsibilities of a specific job.
- a flowing or flow
- the rate of flow of water, as the tide or current, through a defined area
- a continuous movement or continual change: fashion is always in a state of flux
- any excessive or unnatural discharge of fluid body matter, esp. from the bowels
- a substance, as borax or rosin, used to help metals fuse together by preventing oxidation, as in soldering
- in metallurgy, a substance added to metals while they are in a furnace, to remove impurities, promote fusing, etc., as a non-metallic material added to a furnace charge that has the ability to fuse with undesired matter and form a liquid slag that can run off more easily
- Physics the rate of flow of energy, fluids, etc. across a surface
Origin of fluxMiddle English ; from Old French ; from Classical Latin fluxus, a flowing, flow ; from past participle of fluere, to flow: see fluctuate
- to make (a solid) melt
- to fuse (metals) by melting
Archaic to flow or stream out
- a. A flow or flowing of a liquid.b. The flowing in of the tide.c. A continuing movement, especially in large numbers of things: a flux of sensation.
- Constant or frequent change; fluctuation: “The constant flux of people and groups ensures that human gene pools will always be mixed” (Steve Olson).
- Medicine The discharge of large quantities of fluid material from the body, especially the discharge of watery feces from the intestines.
- Physics a. The rate of flow of fluid, particles, or energy through a given surface.b. See flux density.c. The lines of force of an electric or magnetic field.
- Chemistry & Metallurgy A substance that aids, induces, or otherwise actively participates in fusing or flowing, as:a. A substance applied to a surface to be joined by welding, soldering, or brazing to facilitate the flowing of solder and prevent formation of oxides.b. A mineral added to the metals in a furnace to promote fusing or to prevent the formation of oxides.c. An additive that improves the flow of plastics during fabrication.d. A readily fusible glass or enamel used as a base in ceramic work.

- A chemical agent for cleaning metal prior to soldering or welding.
- It is important to use flux when soldering or oxides on the metal will prevent a good bond.
- (physics) The rate of transfer of energy (another physical quantity) through a given surface, specifically electric flux, magnetic flux.

- Flowing; unstable; inconstant; variable.
flux - Computer Definition
- The rate of flow of something such as energy, particles, or fluid volumes across or through a surface. Radiant flux is the time rate of energy flow of radiant energy as measures in watts or joules per second. Luminous flux is radiant flux evaluated with respect to its luminous (brightness) efficiency. See also joule, luminance, and watt.
- The strength of an energy field acting on a specific area.
