What exactly is electric flux?
electric flux, property of an electric field that may be thought of as the number of electric lines of force (or electric field lines) that intersect a given area. The negative flux just equals in magnitude the positive flux, so that the net, or total, electric flux is zero.
Why is electric flux a dot product?
Because flux measures the “flow” through an area, the area vector must no be perpendicular to the flow and this is why flux is found with the dot product.
What is electric flux Ncert?
Electric flux is the measure of flow of the electric field through a given area. Electric flux is proportional to the number of electric field lines going through a normally perpendicular surface. The orientation of area element decides the amount of electric flux. Thus, the area element is a vector.
What is meant by flux of a vector explain with example?
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.
Why is flux a scalar quantity and the dot product of magnetic field and area?
As we are using dot products, the magnetic flux is a scalar quantity. When the magnetic field is along the area of the closed surface, the magnetic flux is 0. It happens because the angle between the area vector and the magnetic field vector is 90°.
What is flux in chemistry class 12?
Flux is the substance added during the extraction of metals. On heating it reacts with the earthly impurities(gangue) to form fusible (molten) mass known as slag. They may be acidic or basic in nature. Acidic flux are is used to remove the basic impurities. For example silica.
What is meant by electric flux write the statement and mathematical form of Gauss’s theorem?
Gauss Law states that the total electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity. The electric flux in an area is defined as the electric field multiplied by the area of the surface projected in a plane and perpendicular to the field.
What is electric flux and relation between electric flux and electric field?
The electric field ( ) is defined as the electric force per unit charge. The electric flux ( )is defined as the electric field times the normal area vector. In Gausses law this quantity is proportional to the amount of charge enclosed by a surface.
