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

Yes, a vector can be represented in terms of a unit vector which is in the same direction as the vector. it will be the unit vector in the direction of the vector times the magnitude of the vector.

The zero vector is both parallel and perpendicular to any other vector. V.0 = 0 means zero vector is perpendicular to V and Vx0 = 0 means zero vector is parallel to V.

Resultant vector or effective vector

Vector spaces can be formed of vector subspaces.

A null vector has no magnitude, a negative vector does have a magnitude but it is in the direction opposite to that of the reference vector.

The poynting vector is that one which represents the directional energy flux density of the electromagnetic field.

Electric flux is a scalar quantity, as it represents the amount of electric field passing through a given area. It does not have a direction associated with it, unlike vector quantities.

No, electric flux is a scalar quantity. It represents the total number of electric field lines passing through a given surface.

The applications are in transport phenomena, in determining the direction of flow in momentum transport, heat transfer, and mass flux.

The surface integral of the electric field is the flux of the electric field through a closed surface. Mathematically, it is given by the surface integral of the dot product of the electric field vector and the outward normal vector to the surface. This integral relates to Gauss's law in electrostatics, where the total electric flux through a closed surface is proportional to the total charge enclosed by that surface.

A flux integral is the summation of the component of a vector field perpendicular to differential surface areas (or in the direction of their normal vectors) over the entire surface. In other words, the flux of a vector field across a surface is the surface integral vector field in the direction of the normal component of the surface.INT INTS[(F*n)dS]INT INT is the double integral operatorS is the surface domain being integrated overF is a vector field* is the dot productn is the normal component to the surfacedS is the differential surface area.Flux integrals are very useful in physics. Two of Maxwell's equations involve flux integrals:INT INTS[(B*n)dS] = 0This equation states that the magnetic flux over a closed surface is always equal to zero. This equation reflects the fact that magnetic monopoles do not exist.INT INTS[(E*n)dS] = Q/EThis equation states that the electric flux through a closed surface is proportional to the total charge enclosed within that surface (1/E is the proportionality constant). These equations played important roles in the discovery of electromagnetic radiation.also the Flux of a velocity field through a surface indicates the flow rate across that surface.

The magnetic flux through a surface is maximum when the magnetic field is perpendicular to the surface and the surface area is also perpendicular to the field. This occurs when the magnetic field is passing through the surface at a 90-degree angle, resulting in the maximum number of magnetic field lines intersecting the surface area.

The net electrical flux passing through a cylindrical surface in a nonuniform electric field is given by the integral of the electric field dot product with the surface area vector over the surface. The flux depends on the strength and direction of the electric field, as well as the shape and orientation of the surface.

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.
