What is flux

Flux is the presence of a force field in a specified physical medium, or the flow of energy through a surface. In electronics, the term applies to any electrostatic field and any magnetic field . Flux is depicted as "lines" in a plane that contains or intersects electric charge poles or magnetic poles.

BEST OF LUCK FOR YOUR EXAMS!!!!!!!!!!!!!!!!!!!!!

In the various subfields of physics, there exist two common usages of the term flux, both with rigorous mathematical frameworks. A simple and ubiquitous concept throughout physics and applied mathematics is the flow of a physical property in space, frequently also with time variation. It is the basis of the field concept in physics and mathematics, with two principle applications: in transport phenomena and surface integrals. The terms "flux", "current", "flux density", "current density", can sometimes be used interchangeably and ambiguously, though the terms used below match those of the contexts in the literature.

The impurities of certain types can be eliminated from the ore in the molten state only.Most of the impurities in the ores dono melt easily at the temperature of the normal industrial furnaces.Therefore "an outside substance,added to the ore to lower its melting point,is knowns as flux
flux+gangue(impurities)---->slag?.

Thanks for asking these questions
