Задача 31374.

The disk radius R = 5 cm shall be uniformly distributed over the surface of the charge Q = 0,1 SCLC. The disc rotates uniformly about an axis passing through its center and perpendicular to the disk plane. Speed n = 50 ^ -1. Determine: the magnetic moment pm, a circular current, generated by the disc; the ratio of the magnetic moment to the angular momentum Pm / L if the disk mass m = 100g.

Detailed solution shorthand terms, formulas and laws used in the decision, the withdrawal of the calculation formula and the response.
