The magnetic dipole created by the two monopoles, i.e. two charges. They ask for this, because they want us to compare this potential (using superposition) with the magnetic potential that is created by a magnetic dipole.
The monopoles are on the Earth's rotation axis, so they are inclined...
Homework Statement
Determine the expression for the potential created by two magnetic monopoles (one positive, the other negative) that are equidistant from Earth's center (a/2 is the distant from each monopole to the Earth's center) and that are placed in the rotation axis.

I have this EDP, uu_{\eta \eta } +u_{\eta }^2=0
and my solution for it, but I don't know if it's correct. Could you tell me if you do or do not agree with it?
Here it's my solution:
1)We can write the EDP as:
(uu_{\eta})_{\eta}=0
2)Integrating:
d(uu_{\eta})=0
uu_{\eta}=F(\xi )
where \xi is...
The extinction index is the imaginary part of refraction index. The physical meaning has to do with the amount of attenuation of the wave. And teh answer for the second question..the only one that I have in mind is the expresion for electric field as a monochromatic plane wave with a complex...
We have a monochromatic plane wave with a frequency ω=10^15 (1/s). It is spread in a medium whose resonance frecuency is also ω=10^15 (1/s). The wave is attenuated in the spreading direction. In 1 cm, the electric field of the wave is 10 times smaller. Give an expression for the extinction index...
