(a) What is the electric flux of this electric field through the surface of a square if
the normal to the surface is in the + x direction? (b) What is the electric flux
through the same square surface if the normal to the surface makes a 60° angle
with the ...

Engineering Electromagnetics
Thus, because this is a density and because it is derived from the electric field,
we will call it the electric flux density. The use of the term "flux"' will become
apparent in the following chapter. We merely want to comment here that the use
of this ...

Electromagnetic Field Theory
Another important concept in electrostatics is electric flux. If a unit test charge is
placed near a point charge, it experiences a force. The direction of this force can
be represented by the lines, radially coming outward from a positive charge.

College Physics: Reasoning and Relationships
Fortunately, there is a simpler way to deal with complex charge distributions,
based on Gauss's law. To understand Gauss's law, we must first define a quantity
called the electric flux. In words, electric flux is equal to the number of electric
field ...

Physics for Scientists and Engineers
Here we abstract the idea of flux one step further. Nothing is flowing in the
electrostatic case. In particular, the electric field is not in motion. Nevertheless,
electric flux lines have many properties analogous to the properties of other kinds
of flux.
In this case, we think of a positive charge as being a source of electric flux and a
negative charge as a sink of electric flux. The flux concept can be carried over to
the case of electric fields simply by defining the total electric flux (ΦE) from a ...

The field lines are then said to represent the electric flux. The electric flux lines
have no real existence but they are a useful concept in the representation,
visualization, and description of electric fields. For an isolated positive point
charge, the ...
