The figure shows three loop models of an electron orbiting counterclockwise within a magnetic field. The fields are nonuniform for models 1 and 2 and uniform for model 3. B (1) (2) (3) For each model, is the magnetic dipole moment of the loop directed up, directed down, or zero? (1) (2) (3) Model (1): V Model (2): Model (3):For each model, is the magnetic force on the loop directed up, directed down, or zero? If if E (I) (9) (3) Model (1): v Model (2): v Model (3): V
