Abstract
We describe an exact derivation of tile total nondissipative transvers e force acting on a quantized vortex moving in a uniform background. T ile derivation is valid for neutral boson or fermion superfluids, prov ided the order parameter is a complex scalar quantity. The force is de termined by the one-particle density matrix far away from the vortex c ore, and is found to be the Magnus force proportional to the superflui d density.
