2. The word flux comes from Latin, fluxUS means
"flow”.
Flux is a measure of how much of a vector
field (ex. magnetic or electric) is going
through a particular surface.
3. In electromagnetism, 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.
4. Electric flux is the total number of lines of force
passing through a surface.
In physical sense, electric flux is defined as:
"The total number of lines of force passing through
the unit area of a surface held perpendicularly.“
Mathematically the electric flux is defined as:
"The dot product of electric field intensity (E) and
the vector area (A) is called electric flux."
5. Where is the angle between E and A.
MAXIMUM FLUX:
If the surface is placed perpendicular to the electric field
then maximum electric lines of force will pass through the
surface. Consequently maximum electric flux will pass through
the surface.
6.
7. If the surface is placed parallel to the electric
field then no electric lines of force will pass
through the surface. Consequently no electric
flux will pass through the surface.
