Question






The figure below 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.



(a) For each model, what is the direction of the magnetic dipole moment of the loop?



(b) For each model, what is the direction of the magnetic force on the loop?
