- 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.
flux definition by Webster's New World
- 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: Middle 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
flux definition by American Heritage Dictionary
- a. A flow or flowing.b. A continued flow; a flood. See Synonyms at flow.
- The flowing in of the tide.
- 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.
- Constant or frequent change; fluctuation: “The newness and flux of the computer industry has meant many opportunities for women and minorities” (Connie Winkler).
- 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.
- To melt; fuse.
- To apply a flux to.
- To become fluid.

Origin: Middle English, from Old French, from Latin flūxus, from past participle of fluere, to flow; see bhleu- in Indo-European roots.
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.
flux - Medical Definition
- The discharge of large quantities of fluid material from the body, especially the discharge of watery feces from the intestines.
- Material thus discharged from the bowels.
- The rate of flow of fluid, particles, or energy through a given surface.
- Flux density.
flux - Science Definition
- The rate of flow of fluids, particles, or energy across a given surface or area.
- The presence of a field of force in a region of space, represented as a set of lines indicating the direction of the force. The density of the lines indicates the strength of the force. Lines used to represent magnetic fields in depictions of magnets, for example, follow the lines of flux of the field. See also field, magnetic flux.
- A measure of the strength of such a field.
- A readily fusible glass or enamel used as a base in ceramic work.
- An additive that improves the flow of plastics during fabrication.
- 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.
- A substance used in a smelting furnace to make metals melt more easily.
