Hello, I have doubts with this problem, I'm not sure, if my solutión is right, so, here we go
Let's two equal charges with the same charge but opposite signs, positive and negative, in a circle, such a distance between them is constant and equal to diametre of the circle. Both charges, turn around the center of the circle with angular speed w. Calculate, the electric dipole moment, and the magnetic dipole moment.
the electric dipole moment, is define as, [tex]\vec{p}=q\vec{d}[/tex], with [tex]\vec{d}[/tex] the vector that go from the positive charge to negative charge.
The system turn around the center, so we have to applicate a rotational matrix to [tex]\vec{d}[/tex], and so, we have calculated the electric dipole moment
The magnetic dipole moment, must be zero, because the charges have opposite signs, and the problem is equivalent to two spirals with circulating intensites in opposite directions.
I think that my solution is too simple, for this reason I mistrust it
Thank's
