flux

Flux describes any effect that appears to pass or travel (whether it actually moves or not) through a surface or substance. Flux is a concept in applied mathematics and vector calculus which has many applications to physics. For transport phenomena, flux is a vector quantity, describing the magnitude and direction of the flow of a substance or property. In vector calculus flux is a scalar quantity, defined as the surface integral of the perpendicular component of a vector field over a surface.

    flux question

    Hi, Would I be right in saying another reason for using flux other then stopping oxides forming on the copper, or using it as a copper cleaner when soldering. Is for flux to release surface tension, when heated and act as a free flowing liquid that follows heat, and performs a capillary action...
