Or, you could envision an object graphics solution with
an "earth" and "satellite" revolving around it, casting
a shadow trajectory onto the earth with a magnetic vector
rotating about in the plane of the satellite.

All I'm saying is, the question lacked enough detail,
for whatever good reason, to know how to form a sensible
answer. And that when you ask better questions, you get--
generally--better answers.

I agree that this question was borderline for such a
response. Even I could tell English was not the first
language. But coming, as it did, at the end of a long
day and after several seriously bad questions from the
past week, I just thought a reminder might be useful. :-)

Cheers,

David
