A magnetic dipole (in the form of a current-carrying round loop) located in an external, inhomogeneous magnetic field $$B$$. The magnetic dipole moment $$\mu$$ is parallel to $$B$$ here, which is why the dipole does not undergo any rotation, but is pulled downwards. A force $$F$$ acts on the dipole in the inhomogeneous field, which causes the dipole to act in the direction of the larger B field.
