Solving a problem in physics section 45 paragraph 33 el

33. A thin ring of 10 g and the radius R = 8 cm carries a charge evenly distributed with a linear density of τ = 10 nC / m. Ring uniformly rotates at n = 15 s-1 with respect to an axis perpendicular to the plane of the ring and passing through the center. Determine: 1) the magnetic moment Pm circular current generated ring; 2) the ratio of magnetic moment to the pulse ring.
