flux

flux (fluks)

noun

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
1. a substance, as borax or rosin, used to help metals fuse together by preventing oxidation, as in soldering
2. 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

Etymology: ME < OFr < L fluxus, a flowing, flow < pp. of fluere, to flow: see fluctuate

transitive verb

intransitive verb

Archaic to flow or stream out

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.

Converse of object

emit: The change in IR flux emitted by the scene can be detected by monitoring the voltage generated by the thermocouple.
quantify: The primary goal is to quantify accurately the global air-sea fluxes of CO 2.
solder: This is another time you might want to clean the board to remove left over soldering flux.

Adjective modifier

luminous: Clearly the luminous flux of a light source is of little value in isolation; the light will be changed by the optics.
coronal: Long-term changes in the solar photosphere associated with changes in the coronal source flux.
magnetic: The PK Ring is a 100 % Neo Magnet, with a strong magnetic flux around all external faces.
radiant: All samples reflect radiant flux, while only some transmit it.
cosmic: But the incoming cosmic ray flux, which would otherwise be isotropic, is shaped by the Earth's magnetic field.
plasmaspheric: During storms of this type, the role of plasmaspheric fluxes dominates at middle to low latitudes.

Modifies a noun

density: M Magnetic flux density A measure of the magnetic effect induced in a medium by an external field.
pinning: Trapped field measurements suggest that these samples exhibit increased flux pinning which may be enhanced further by irradiation with thermal neutrons.
calibration: No wavelength calibration or flux calibration have been applied.
residue: Use water as a solvent, either in combination with detergent to remove rosin flux residues or in conjunction with water soluble fluxes.
fume: Typical contaminants are exhaust fumes from lorries parked outside the air compressor intake, flux fumes, halogenated solvents and oil from unsuitable compressors.

Noun used with modifier

air-sea: The primary goal is to quantify accurately the global air-sea fluxes of CO 2.
photon: This is achieved by simulating the photon flux with a pixel array.
X-ray: Due to vignetting, this order is approximately but not exactly the same as the order by X-ray flux.
neutrino: Its purpose is to study hadron production for the neutrino factory and to aid understanding of the atmospheric neutrino flux.
sediment: These daily gaging stations provide the best information available on sediment flux in the Nation's rivers.
solder: One cell tab is nickel and the other aluminum so you will require an aluminum solder flux - or spot weld.
