As flux roughly means 'flow', in various contexts it means 'rate of flow' and/or 'amount of stuff happening', in a turnover sort of way.
This sense pops up in
- physics,
- biology (movement of chemicals, sometimes specific to metabolism),
- but also physiology and a few other places.
In physics:
- Electric flux is a property of an electric field
- luminous flux is amount of visible light, radiant flux refers to any electromagnetism (verify) (see also flux in the human perception of light)
But also:
- In metallurgy (e.g. welding) flux is about cleaning and purifying agents to keep things flowing
- in welding it might refer to anything that helps keep the weld pool clean
- in soldering, soldering flux is often specifically an acid that removes oxidation -- so that solder can flow more easily
- 'acid flux' refers to a specific type of such flux
Also as a name for some things, probably because it sounds vaguely cool
- Flux is a query language used by InfluxDB
