flux Scientific  

/ flŭks /

1. The rate of flow of fluids, particles, or energy across a given surface or area.

2. 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.
