Define a vector field in physics. Give two examples that are not of electric or magnetic origin. Are the fields you have chosen time-dependent or not? Draw a sketch of each of the fields you have chosen.This means that you should sketch the field vectors at different points.

For a particular polarization of light, the time dependent
portion of the electric field Eₒ and
magnetic field Hₒ are given by the
expressions
Eₒ = 4sin(ωt)(i hat) + 4cos(ωt)(j hat)
+ 0(k hat)
Hₒ = 4cos(ωt)(i hat) + 4sin(ωt)(j hat)
+ 0(k hat)
where ω is a constant (the frequency of the light) and t is
time.

GOAL Use the superposition principle to calculate the electric
field due to two point charges. Consider the following
figure.
The resultant electric field at P equals the
vector sum 1 + 2, where 1 is the
field due to the positive charge q1and
2 is the field due to the negative charge
q2.Two point charges lie along the
x-axis in the x y-coordinate plane.
Positive charge q1 is at the origin, and
negative charge q2 is at (0.300 m, 0). Point...

magnet with the poles labeled). Do four different examples:
magnetic field up, magnetic field down, magnetic field left,
magnetic field right.

Did any of your field lines cross? Should they? Why, or why
not?
None of the field lines crossed, nor should they. They are a
line of constant potential and the equipotential can have only one
value at a given point in space. If the electric field lines were
to intersect, they would render a location with two different
strong electric field vectors and so would not accurately represent
equipotential lines.
Did any of your equipotential surfaces cross? Should they?...
