How do you get negative flux?

How do you get negative flux?

To compute the flux, we see how aligned field vectors are with vectors normal to the surface.

1. When the field vectors are going the same direction as the vectors normal to the surface, the flux is positive.
2. When the field vectors are going the opposite direction as the vectors normal to the surface, the flux is negative.

Is magnetic flux always negative?

3 Answers. Yes, magnetic flux can be negative. It just depends on where the field is going. Say there is a sheet and magnetic field is going through it from front to the back, we can call the flux there as positive and negative when it’s the other way round.

What is slag used for?

While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of the smelting, and minimizing any re-oxidation of the final liquid metal product before the molten metal is removed from the furnace and used to make solid metal.

What is slag example?

Slag is waste matter separated from metal during smelting. An example of slag is the iron and silica that is removed during copper and lead smelting. An example of to slag is for the heat of copper smelting to remove the iron and silica from the copper.

Is Borax a basic flux?

Flux. A mixture of borax and ammonium chloride is used as a flux when welding iron and steel. It lowers the melting point of the unwanted iron oxide (scale), allowing it to run off. Borax is often used as a flux for forge welding.

How do you identify basic and acidic flux?

– Acidic flux is the substance added to molten metals to bond with basic impurities that can be readily removed. – For example, silica is used to remove calcium oxide impurities from the ore. – Basic flux is the substance added to molten metals to bond with acidic impurities that can be readily removed.

What type of flux is used when gangue is acidic?

Basic fluxes like lime (CaO) or MgO are used to remove acidic gangue such as Silica.

Is CaO a base flux?

Basic flux removes acidic impurities, Examples of basic flux Limestone, Fe2​O3​, MgCO3​, CaO, etc.

Which is the following is not a basic flux?

Quicklime is known for its wide range of uses, involving in the formation of iron and steel, paper and pulp production, also the treatment of water and flue gases and in the mining industry. Hence, Option (A) Silica is correct and it is not a basic flux.

Which one of the following is NOT basic flux?

SiO2 in an acidic flux.
