What Does Flux Mean?

Flux is a common phenomenon throughout the natural world and has become a ubiquitous concept throughout physics and mathematics, and hence technology. Flux describes the flow of a physical property through space and is often coupled with a time variation. There are two common usages or contexts for flux, each having solid mathematical frameworks – flux as a vector in the context of transport phenomena and flux as a scalar quantity in the context of electromagnetism.
