A charge q is distributed uniformly around a thin ring of radius r. The ring is rotating about an axis through its center and perpendicular to its plane, at an angular speed w.

1. What is the direction of this magnetic moment if the charge is positive?

2. Show that the magnetic moment due to the rotating charge has magnitude u=(.5)qwr^2.
