Paul realized that it is possible to design a magnetic field with a local minimum in the field strength, and if the magnetic dipole is originally aligned to seek a position where the field is weakest, it will remain aligned in the «weak field - seeking» orientation [see «Cooling and Trapping Atoms,» by W. D. Phillips and H.].
