fluct-, flucti-, -flux, flu-, flum-, -fluent, -fluence

(Latin: flow, flowing; moving in a continuous and smooth way; wave, moving back and forth)

flux guide
In induction heating, an equipment component that guides the magnetic flux to preferred locations.
flux leakage
Any magnetic flux used in electromagnetism that does not pass through the part of a magnetic circuit where it is needed.
flux linkage
Te passage of magnetic flux that is produced in electromagnetism by one component or circuit through another component or closed circuit, creating a magnetic interaction between the two.
flux of energy, energy flux
A quantity measuring the rate of energy flow; the energy per unit time per unit area traveling across a surface element that is perpendicular to the energy flow.
flux path
In electromagnetism, a path in physical space that a magnetic flux line follows.
flux pinning
In materials science, the prevention of flux movement and resulting quenching of a superconducter by the use of ultra-thin filamentary composites that lower the risk of flux jump.
flux pump
A cryogenic generator capable of hanging small inputs of alternating current into large outputs of direct current.
flux refraction (s) (noun), flux refractions (pl)
An abrupt change in direction of magnetic flux lines at the interface between two materials having different magnetic permeabilities.
flux sensor
A sensor that measures the flow of energy as a fluid.
flux unit
Astrophysics, the unit of flux density or "brightness" used in radio astronomy.
flux, fluxion
1. The measure of the flow of some quantity per unit area per unit of time.
2. Any substance that will promote the melting of another substance to which it is added.
3. An excessive discharge of fluid.
4. A resin or similar substance that is used in soldering, welding, or brazing in order to remove oxides from the surfaces to be joined and so promote their bonding.
5. In electromagnetism, the electric or magnetic field lines of force that traverse, or through, a given cross-sectional area.
6. Etymology: from Old French flux, which came from Latin fluxus, past participle of fluere, "to flow".

Originally it referred to "excessive flow" (of blood or excrement); an early name for "dysentery"; and then the sense of "continuous succession of changes" is first recorded in 1625.

1. A flowing or passing away, and giving place to others.
2. Discharging of large quantities of fluid material from the body; especially, the discharge of watery feces from the intestines.
3. The flowing of fluid, particles, or energy through a given surface.
flux-cored welding
Welding using a filler metal that contains a flux in its core.
flux-density mapping
A process by which radiation flux density is tracked within a reactor or other radiation source.
1. Capable of being melted or fused, as a mineral.
2. The ability to move or to progress freely as if in a stream.
