The purpose of flux is to clean oxides from metal surfaces to ensure a clean bond in soldering or brassing them together. without a proper flux soldered and brazed joint integrity is unreliable.
You must use flux while brazing because the flux prevents oxides from forming while the metal is heated. The flux also serves the purpose of cleaning any contamination left on the brazing surfaces.
Gd
To maximise the magnetic linkage and flux density between the primary and secondary windings.
After cleaning copper pipe and fitting, applying flux helps ensure that solder will adhere to pipe and fitting when joint is heated to proper temperature.AnswerIt depends on what type of 'flux' you are talking about? For example, 'electric flux' and 'magnetic flux' exists naturally, and is not 'for' anything in particular, although it can be made use of.
flux acts as a wetting agent in the soldering process, reducing the surface tension of the molten solder and causing it to better wet out the parts to be joined.
i) leakage flux is those flux which goes through the air and linkage flux is those flux whose go through the cell. ii)leakage flux is the loss at flux but linkage flu is warning flux. iii)leakage flux is cause of eddy current loss and linkage flux is case of copper loss.
The Ratio of the total flux ( flux in iron path) to the useful flux (flux in air gap)
when a current flow through the coil then flux produced around the coil . if the flux linked same produced coil only then the flux is said to be leakage flux. flux produced by one coil ,but linked with another coil then the flu is said to be mutual flux.

The primary purpose of flux is "to clean". It mixes with the elements in the molten puddle and removes impurities. As it cools it floats to the surface and creates the slag which prevents Oxygen from attacking the Iron.
