What is the direction of this magnetic moment

Reference no: EM13561201

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

a) Show that the magnetic moment due to the rotating charge has magnitude u = 1/2(qwr^2).

b) What is the direction of this magnetic moment if the chargeis positive.
