∙ 9y agoElectric flux is a scalar quantity, because it's the dot product of two vector quantities, electric field and the perpendicular differential area.
This is written in terms of differentials as:
dΦE = E � dA,
where dΦE is the differential electric flux, E is the electric field, and dA is the perpendicular differential area. Bolded quantities are vectors.
However flux-density is a vector quantity and electric flux density is related to electric field by a constant called the permittivity.

What in this world have magnitude but no direction?
Those having only magnitude but no direction are known as scalar quantity. Time, mass, work, power, electric current, electric charge, moment of inertia, magnetic flux, electric flux and so many are found to be scalar in this world.
Why vector quantities cannot be added or subtracted like scalar quantities?
SCALAR QUANTITIESPhysical quantities which can completely be specified by a number (magnitude)having an appropriate unit are known as "SCALAR QUANTITIES".Scalar quantities do not need direction for their description.Scalar quantities are comparable only when they have the same physical dimensions.Two or more than two scalar quantities measured in the same system of units are equal if they have the same magnitude and sign.Scalar quantities are denoted by letters in ordinary type.Scalar quantities are added, subtracted, multiplied or divided by the simple rules of algebra.EXAMPLESWork, energy, electric flux, volume, refractive index, time, speed, electric potential, potential difference, viscosity, density, power, mass, distance, temperature, electric charge etc.VECTORS QUANTITIESPhysical quantities having both magnitude and directionwith appropriate unit are known as "VECTOR QUANTITIES".We can't specify a vector quantity without mention of deirection.vector quantities are expressed by using bold letters with arrow sign such as:vector quantities can not be added, subtracted, multiplied or divided by the simple rules of algebra.vector quantities added, subtracted, multiplied or divided by the rules of trigonometry and geometry. EXAMPLESVelocity, electric field intensity, acceleration, force, momentum, torque, displacement, electric current, weight, angular momentum etc. REPRESENTATION OF VECTORSOn paper vector quantities are represented by a straight line with arrow head pointing the direction of vector or terminal point of vector. A vector quantity is first transformed into a suitable scale and then a line is drawn with the help of the scale choosen in the given direction. By : Shoaibbilal64@Yahoo.com
When the wire loop of a generator turns an electric current is produced?
The flux density of that coil becomes greater.
What is the symbol for electric flux?
psi
What is the name of a symbol of electric flux?
psi
What is flux density related to?
In case of electrostatics, flux density = electric field intensity and in case of magnetism, flux density = magnetic field induction

Those having only magnitude but no direction are known as scalar quantity. Time, mass, work, power, electric current, electric charge, moment of inertia, magnetic flux, electric flux and so many are found to be scalar in this world.
What is the poynting vector?
The poynting vector is that one which represents the directional energy flux density of the electromagnetic field.
What are the difference between elactric field and electric displacement field?
The electric displacement field is a vector field, shown as D in equations and is equivalent to flux density. The electric field is shown as E in physics equations.
Is flux a vector?
In chemical engineering, we deal with molar fluxes and I am very sure molar flux is not a vector, it is simply a scalar. molar flux cannot be negative because you cannot have - 5.0 moles of something flowing but I think you'll have to verify for other cases like magnetic flux and electrical fluxes
How does flux increase?
Flux incresed with the increase of scalar quantity

What is maximum and minimum electric flux?
As we know that electric flux is the total number of electric lines of forces passing through a surface. Maximum Flux: Electric flux through a surface will be maximum when electric lines of forces are perpendicular to the surface. Minimum flux: Electric flux through a surface will be minimum or zero when electric lines of forces are parallel to the surface.
When the wire loop of a generator turns an electric current is produced?
The flux density of that coil becomes greater.
What are the two main types of flux?
Types of flux - Electric and Magnetic Flux. Electric field flux through a closed surface is equal to the change enclosed in the surface, or the rate of change of magnetic flux is equal to the induced voltage around the surface.
How do you calculate total flux when flux density and magnetic field strength has been?
once flux density is known multiply to it the area perpendicular to the flux lines . the product is the total flux passing through the area. If field strength is known , get the flux density by pultiplying to it the permeability of the medium. then flux can be obtained as above. from : govind Kunkolienker kunkolienker@yahoo.com
Relationship between flux density and field strength?
In simple terms, if flux density increases, then field strength increases and vice versa. The flux density is equivalent to field strength times with a variable.
