The figure shows four orientations, at angle , of a magnetic dipole moment r r magnetic field b (i) (4 pts) if the dipole moment r is rotated from orientation (2) to orientation (1) by an. Negative external agent, is the work done on the dipole by the agent? (circle one) (ii) (4 pts) rank the work done on the dipole by the agent for these three rotations, greatest first: In the figure below, two semicircular arcs (i & ii) have radii r1 = 4. 10 cm and.
