Problem 2 A two-layer ring of surface charge lies in the x-y plane and is centered on the origin. It has inner radius 6.5 m and outer radius 11.7 m. The top layer of surface charge is uniformly distributed and has charge density +4.2 x 10-6 C/m². The bottom layer of surface charge is equal and opposite (negative). The two layers are very close together so both can be approximated as lying in the x-y plane. The top layer rotates at 25 radians per second, and the bottom layer remains stationary. The moving charges in the top layer constitute a current, and this system is like a circular current loop. The system is surrounded by empty space (vacuum). Q11: What is the total magnetic dipole moment of this system? 0.883 A m? 1.40 A m? O 2.67 A m? O 3.82 A m? O 0.637 A m2
