Electromagnetism for Engineers

Use Matlab to e
valuate the effect of electric dipole charge Q and distance
d on the electric field intensity and potential.
2.
Use Matlab t
o plot the electric field and equipotential lines due to:
a.
Two point charges Q and
–
3Q located
at (x, y) = (
–
2, 0) and (1, 0)
respectively
b.
Four point charges Q,
–
Q, Q,
–
Q located at (x, y) = (
–
1,
–
1), (1,
–
1), (1,
1), (
–
1, 1)
For simplicity, assume
for
the second objective
that Q = 4
pe
0
and
–
10 < x,
y < 10
Theory
:
Electric dipole is two point cha
rges of equal magnitude and opposite polarity
separated by a very small distance compared to the distance where the field is
calculated
