A simple Hamiltonian determines in closed form the potential of the long-range force between two fixed molecules polarizable magnetically as well as electrically, exposed to blackbody radiation at temperature T. The results apply provided kT≪ħΩ and at separations ρc/Ω, with ħΩ a typical molecular excitation energy.
