## Main Question or Discussion Point

Why is there no kinetic energy term in said hamiltonian? Suppose I take a magnetic dipole in my hand, and I throw it in the field. Then surely its classical energy is E = p²/2m - [itex]\vec{\mu} \cdot \vec{B}[/itex].

Then why is the p²/2m term absent in the hamiltonian?
